What is SEMANTIC SEARCH and why should you care?

I talk to many folks about a wide variety of topics and enjoy just discussing random issues with random folks on the street, and use the insights from these conversations to understand how the public think and what is important to folks in various different work environments,  focusing specifically on the online marketing issues that unfold when evaluating what has been discussed.

The fact that I talk to many folks about marketing, in all its forms also allows me to have an understanding of how online marketing issues which are  being promoted by so called online marketing experts, and folks who are knowledgeable within the online marketing industry  are not taking the Google Hummingbird algorithm into account.

Google Humming Bird algorithm has been around very close to three years now, (introduced August / September 2013)  but many online marketing folks still do not know what this is and have no clues as to how Google humming Bird algorithm  impacts on search results within the Google search engine.

Since the Introduction of the Google Humming Bird algorithm in August / September 2013 there have been many folks using the click bait technique of saying that a specific SEO (Search Engine Optimization) technique such as the use of keywords or page titles in the HEAD section of an HTML document is dead and no longer relevant to search engines as a tool, to evaluate the content of your page for a match to a search query.  See this post by Garenne Bigby   discussing the death of SEO

This has lead to the public believing that these issues, techniques and tactics are no longer used by Google to evaluate the context  and intentions of your online content.  It has thus come about that the public, and most online marketing folks, now ignore and neglect to use these very valuable SEO (Search Engine Optimization)  tools, with the vast majority of folks who make use of the social media as an online marketing base not even knowing of the existence of the Google Humming Bird algorithm

I have written about the impacts and some issues associated with Google Humming Bird algorithm before and here are a few links to posts discussing #googlehummingbird 

These posts were selected randomly from an internal search of this blog and you may get the full list by typing "google humming bird" into the internal search engine of this blog.

Now to answer the question I posed "what is SEMANTIC SEARCH and why should I care"  I look at it from this angle....

SEMANTIC SEARCH within the context of Google search  is basically (at least in my mind) the complete operational output of the Google Humming Bird algorithm, where Google is trying to match the intent of a search query with the intent of an online document. Semantic search thus involves many new concepts that the old keyword style search (Pre-Google Humming Bird) could not achieve

Below is a very limited list of things that are addressed within the context of Google Humming Bird algorithm, which Google uses to improve the quality of their search results also known as #SERP or Search Engine Results Pages. Remember that the introduction of the Google Humming Bird Algorithm signaled the change from exclusively using strings, to using strings, things, and the connections between strings, things, individual identifiable  digital entities and   the understanding of the content as well as context and semantics of an online document, and includes  a host of new indicators such as but not limited to

  • the semantic footprint of the online document in question
  •  author credibility and the semantic footprints of identifiable contributors to the online document in question.
  •  Semantic footprint and credibility of the publisher of the document in question
  • identifiable  Social interactions within the public social media arena, linking to the document in question, up to a few network levels past the original posts within the social media space,
  •  The semantic footprint of identifiable and verifiable online  documents which have links pointing to the online document in question.
  • The semantic footprints of other online documents linked to from the online document in question  
  • The semantic footprints of digital entities mentioned within the HEADER section in the HTML data of a text document or the EXIF data of a non text document if it exists
  • Semantic connections between META DATA in the HEAD section of HTML documents and the perceived (Googles perspective) purpose, intent, aims and objectives of the online document in question   making the following list of meta data components important from an SEO perspective
    •  page titles
    • page descriptions
    • keyword lists
    • author  / contributors
    • publisher  / document hosts
    • language
    • expiry date when applicable
There are a vast number of new things that search engines are  looking at today, that were not considered pre-Google Humming Bird algorithm, and most folks within the online marketing industry  are oblivious to these, even though they are using many of them very regularly. Most of these issues link back to the SEMANTICS of  the search query and the  SEMANTICS of the individual online documents within the SERP's or Search Engine Results Pages
from the perspectives of the collective semantics of all the components of the online document in question 

Now to answer the why should I care part, one needs a true description of SEO (Search Engine Optimization)    From a #FUFISM perspective SEO is ALL the work done to ensure that your intended target market audience find  your online content when searching for semantically related issues online, and then actually consume that content, and take your desired CTA (Call To Action) seriously then follow through by completing that specific stage in your  audience activity funnel, sales funnel or conversion funnel.

It thus follows that having an elementary understanding of SEMANTIC SEARCH  will be very advantageous for your online marketing success, so you really do need to get to grips with SEMANTIC SEARCH and the associated issues of Google Humming Bird Algorithm

Enjoy the rest of your day and many thanx for reading my post.

The influence of your SEMANTIC FOOTPRINT

SEMANTIC FOOTPRINTS are powerful bread crumb trails that lead to your online work, and leave evidence for search engines to discover where your  expertise and interests are exposed to the world, so that these may be added to their database in ways that search engines are able to use this  info in their algorithms to ensure that your online content is matched to your areas of expertise for purposes of crediting your content with both author and publisher expertise values.  this ensures that your work gets the attention it deserves within the SEO (Search Engine Optimization) space

SEMANTIC  TRUST and SEMANTIC FOOTPRINTS are  becoming ever more important  in terms of SEO (Search Engine  optimization) as  Search Engines improve their ability to identify individuals  and the niche  where they are knowledgeable  or have some expertise

Authors, contributors and publishers that have not yet started to make use of this in terms of their branding and marketing  tactics need to evaluate this and see how this should be used in terms of their online Marketing  strategies where SEO is important  to ensure that HIGH QUALITY  traffic  is driven from  all search  engines to your online business pages.

SEO or Search Engine Optimization  is not only the in-page stuff but also includes off pages stuff as well as off line marketing such as newspaper  marketing and radio advertising.  I have blogged about this before here

FUFISM as a marketing philosophy helps develop your marketimng strategies.

FUFISM or Functional User Friendly Integrated Social Media is a marketing philosophy where SEO and Social media are the two primary concerns when doing all online marketing.

These two issues of SEO and Social Media should work as a team to inform your other marketing tactics about the value of  specific semantics and related terminology that should be used to influence your intended target market to use your selected keywords and related terminology in their online searches for your online content.

SEO has changed over the years from purely a string function to now include a host of new issues and comes in three parts
1) #IPSEO or In Page Search Engine Optimisation
2) #OPSEO or Off Page Search Engine Optimisation
3) #OLSEO or Off Line Search Engine Optimization

the first two (IPSEO and OPSEO) are well known and used extensively however the third option here OLSEO or Off Line Search engine Optimization  is not clearly understood though it is widely used  (unknowingly) by a large section of the marketing industry.  The issue with OLSEO is that most folks do not connect their offline marketing with their online marketing and treat the two as separate entities, which have no relationship at all.  this is how ever rather short sighted, as the off line world is where your marketing, sales and front end office staff actually connect and communicate eyeball to eyeball with your customers who are the core of your intended target market audience.

The off line environment such as news paper and other print marketing gets your intended target audience ( customer base ) to use your selected keywords and other semantically related terminology when search for your products services or information within the online environment.

This means that one could nearly replace ONLINE MARKETING with SEO

SEO has really changed drastically since the introduction of the GOOGLE HUMMING BIRD ALGORITHM,  but most marketing staff have no clue that #GOOGLEHUMMINGBIRD actually exists and even less know what the #HUMMINGBIRDALGO does.

What do you know about document trust within the online marketing industry?

Document trust outline.

in this document when we talk of Document Trust we are actually discussing the digital trust  between two online documents.

Document trust is a concept used extensively by search engines to evaluate a number of variables that would feed back into the search algorithms, as SEOVI (Search Engine Optimization Value Indicators) and have a rather serious impact on search results.

What most folks forget is that there has been an awful lot of work going on in the back ground where the search engines have indexed content, then sent out spiders following each and every out bound link found in  the document,  in turn, and creating a trust table between the two linked documents. These trust tables are then consolidated into a single trust table for each of the two ends of the link.

Within the online marketing industry web pages, blog posts and social media posts are each considered as documents, then there is the plethora of true documents that are  available to the public within the online environment such as  but not limited to

·                     PDF files
·                     images files
·                     video files
·                     office documentation
·                     spread sheets
·                     price lists or product lists
·                     data base files

When an end user of the search engine places a search query, the search engines such as Google, Yandex, Bing or MSN, they receive an answer within fractions of a second, and it seems like magic.

The judicial use of the many HTML attributes that are available is essential here, as things like, but not limited to  the list below will all add different trust values to the documents at each end of the link in many strange and devious  ways.  Also remember to evaluate the content of the HEAD SECTION of blogs and web pages that you own and manage, as many of the issues listed in the  list below can be added to the head section of a page, as well as being used as an attribute within the HTML code of  specific out bound links with very good impacts on your SERP's (Search Engine Results Pages).

·                     REL = AUTHOR
·                     REL = PUBLISHER
·                     REL = CANONICAL
·                     REL = NO FOLLOW
·                     REL = NO INDEX
·                     TITLE = XXXXXXX
·                     DESCRIPTION = XXXXXXXXX 
·                     KEYWORDS = XXXXXXXXX
·                     ALT = XXXXXXX

many of these HTML attributes can also be added to the EXIF DATA of documents such as but not limited to

·                     image files
·                     video files
·                     text files
·                     PDF files
·                     spread sheets
·                     price lists
·                     product catalogues

EXIF data when present in embedded files, such as but not limited to images, videos, audio or text files, has a very large and highly positive impact on many different aspects of the document trust table for any two online documents. The inclusion of things like the REL = AUTHOR, REL = NO INDEX and REL = PUBLISHER allow the search engine to include the great value that comes along with author expertise and specific subject matter accreditation due to the depth of the semantic foot prints of both authors and publishers.  These issues add great trust value to specific sections of both documents, which improve your over all rankings in the SERP's.

The content and context of each document is evaluated and compared for semantic matching directly between the two separate documents.  The next step is to compare the semantic matching between the lists of linked pages (out bound links only) for each page separately, creating two new trust tables that include data from all out bound links in each of the two documents in question and then comparing the two documents in question for semantic matching so that the search engines may determine if the out bound link has any value to the end user, specifically from the point of view of expanding the conversation or adding depth to a specific topic.

The depth and breadth of semantic matching between the two documents in question,  and the other documents that they link to,  is also a major trust factor issue, and how this matches up with any author or publisher semantic footprints is included in the trust based issues that search engines are looking at post HUMMING BIRD.

Document trust has always been an issue with search engines, and document trust has been used quite extensively in a number of sneaky and devious ways to establish algorithms like PANDA  and PENGUIN which are in place to add negative trust signals to pages and documents  that are marketed in ways that step outside of the rules which search engines expect publishers to abide by.  Those algorithms which add positive trust factors are not discussed openly by the staff at search engines, as this would give the black hat search industry a heads up of where and how they may game the system.  Those algorithms which have a negative impact are discussed at great length, in many forums, so that the public may know what SEO  and other online marketing  tactics to avoid or suffer the consequences.

Within the human environment there is intuition and gut feelings that have a very large influence on interpersonal trust, however within the online search environment where machines evaluate online documents through the use of algorithms there is no such tool for the search engine to use.  Search engines rely extensively on links between documents to connect the dots between different digital entities, and then understand the context and intentions of each specific document as best they can.  The more inbound links a document acquires over time the bigger the data pool that is available to a search engine to correctly determine the purpose, aims, objectives and intent of your online content.  That being said, you still need to avoid link farms and other black hat link building tactics, because inbound links from documents that have nothing in common with your online content can, and will hurt your trust factors significantly.

This is the main reason that content marketing as an SEO tool and tactic is so valuable. Content marketing allows you the luxury of expanding the conversation in meaningful ways, and the ability to include a host of extra trust signals in the form of but not limited to the list below...
·                     author signals
·                     publisher signals
·                     semantic matching
·                     context alignment
·                     purpose clarification
·                     intention definitions
·                     audience identification

It is thus important that when you do your content marketing, you take these document trust signals into account and use them wisely.   Avoid spamy forums, communities and groups that discuss wide range of divergent topics, and try to find focused niche areas where you can do your content marketing in ways that fit into the platform where you are doing your content marketing.  Be sure that the areas where you do your content marketing have a high semantic or context correlation with your online work whenever you can.  Using a social media business profile and keeping the content there focused on your niche target market topics is essential.  Keeping conversations active by replying to comments and placing relevant links to expand the conversation within the comment stream of all your social media activity is a very important part of your trust factor development strategies that needs you attention, as this boosts your trust factors in many strange and interesting ways.

Generating digital trust for your online content is not an easy task, as it is made up of a very large collection of many small tasks, some of which seem rather mundane and irrelevant AS TRUST SIGNALS.  These small things make up the bulk of the trust factors that search engines use when evaluating your online content, so take care to understand the value of digital trust and how it is acquired or destroyed through your supplemental marketing and the areas that you may use for your supplemental marketing.

What is digital trust and why should you care?

What is digital trust and why should you care?

Before we talk about DIGITAL TRUST,  we need to examine trust as an interpersonal issue, then using the insights of trust between people, we need to understand how a search engine may use these trust issues between different digital entities.

The big issue that we need to come to grips with, is SEMANTIC TRUST between different digital entities, and how this impacts on the SEOVI (Search Engine Optimisation Value Indicators), which are carried across with hyperlinks between different digital platforms, as well as the semantics and  related context of the content at each end of the link in question.

So what do you Understand about interpersonal trust?

This is a very loaded question, and everybody that I have spoken to during my research on the issue of interpersonal trust,  has come up with a different answer, using their own personal life experiences as a guide line for their answer.  There is no right or wrong answer here, as different culture groups, different religious communities, and different social classes all have their own rules and evaluation processes when dealing with trust.

People of the same groups will always trust each other before trusting an outsider, and past history of interpersonal conversations and interactions between individuals and groups or communities,  will always have a big influence on trust flow patterns. The difference in social standing and educational status between two individuals will also have a very large impact on the relationship and trust flow issues between them.  People of higher social status such as teachers, lawyers, managers or law enforcement officers will usually be trusted before ones peers or those lower down the social ladder.  Known persons would normally be trusted before unknown individuals, and family will usually be trusted before outsiders.

Now trust itself is a very delicate thing, and it does not just suddenly have a very high positive value without a long track record of positive interpersonal interactions.  Just one minor breach of trust, be it a true breach of trust or only a percived breach of trust, can cause a total collapse of all trust between two individuals.  Once the trust between two individuals is broken, it takes quite some considersble effort to repair the trust factors between them, and the breach of trust is not easily forgotten, though it may or may not be forgiven.

When any breach of trust is not forgiven, these two individuals may never have a trusting relationship of any nature again, and the individual who stepped outside of the trust zone and breached the trust between them may also have a host of new problems, The agrieved party may or may not inform other members of their commuity, and many others of the wrong doing, as well as requesting others to also  adopt a bad trust attitude to this specific individual.

Search Engines

Search Engines have evolved over the years and are constantly looking at new and novel ways to improve the quality of their SERP's (Search Engine Results Pages). During 2015 Google, as well as other search engines started using digital trust, as well as related SEMANTIC trust issues as SEOVI (Search Engine Optimization Value Indicators) in more aggressive ways.

Digital trust is like standard human trust in  many ways, except that there is no intuition, such as that when people look into the eyes of those who they are evaluating from a trust perspective, and then base their trust flow issues on GUT FEELING, either positive or negative.  Search engines do not have the luxury of being able to eyeball information in the same way that we as humans eyeball each other. That does not mean that search engines do not have tools and algorithms that evaluate information from a trust perspective, because many search engines have worked hard at developing AI (Artificial Intelligence) specifically to evaluate all online content for a large number of different trust signals.

Links used to be the primary source of digital trust, until the Black Hat Search Engine Optimization fraternity worked out how to game links through the use of link farms, and thin content, with many identical pages in the same website.  Google then developed trust factor algorithms like PANDA and PENGUIN which carried punitive implications for those on the wrong side of the trust equation. Both Penguin and Panda  have built in forgiveness factors, but they do not forget about your transgressions, and keep your web site listed as a past cheater within their trust tables and associated data bases. The forgiveness factors are directly linked to your SEO cleanup efforts  by doing things such as removing thin content, duplicate content and irrelevant links from your pages, and following the recommended procedure to have inbound links either removed or added to your "DISAVOW FILE" .

Links are still vitally important, and the REL = XXXXXXX HTML attributes carry many extra high value SEOVI (Search Engine Optimization Value Indicators) along with them when used in the right manner. It must be remembered that search engines nowadays look at both ends of the link, and evaluate the content on both sides (out bound link and inbound link) as well as the SEMANTIC relationships and context matching issues, for both sides of the link, among many new SEOVI.

AS an example if the REL = AUTHOR attribute is used properly
within the HTML structure of your online content it should  point to the Authors bio page, and have links to all other areas where the specified author contributes within the online environment are listed, and include but is not be limited to the following list:

·                    any Social media profiles that this individual may own
·                    Social media business profiles where this individual is a contributor, owner or manager
·                    blogs where this author contributes as a guest author
·                    web sites where this author is a copy writer, or where his / her work is shared and distributed.
·                    communities, groups and forums where this individual is active in some way, like a moderator, an owner, a manager or a major contributor.

This allows search engines to build a vast trust base, in the form of a trust table, which would allow the search engine to compare all online content associated with this individual author and then form an opinion on this individual authors trust factors and knowledge base, giving them individual trust scores for a host of issues ranging from subject matter to personal representational issues and inter personal relationships with other authors, publishers and general contributors to the online environment amongst the more important SEOVI (Search Engine Optimization Value Indicators)

Trust between individual pieces of online content is a complicated issue, where things like authors, publishers, contributors and information consumers (actual viewers) are all evaluated for semantic relationships as well as a host of other network related issues. The relationships between the platforms where each side of the link is hosted are important variables here, and the expansion of the conversation is the primary issue at stake.  If the search engine determines that there is no semantic linkages between the two linked pieces of online content, then the trust factors may be negative, depending on the inclusion or not of the NO FOLLOW attribute .

This is an important issue that needs to be clearly understood by your marketing team, which should be recommended by your SEO team, and implemented by your design team. Any non related links need the attention of the SEO team, who should have a clear marketing brief discussing the purpose, aims, objectives and intentions of the content in question, so that they can do thorough keyword and target market research.  Most websites and blogs carry advertising and marketing links that are not directly related to the online content that they are housing, and these may need to carry the NO FOLLOW attribute, and possibly also the NO INDEX attribute, or perhaps only the NO INDEX attribute, so as to give search engines very clear signals of the focus area and topics that your online content is offering the public at large. 

These two attributes are very powerful trust generators, as they indicate to a search engine that the linked content is not related to the IN-PAGE content, and it should be standard IPSEO (In Page Search Engine Optimization) PRACTICE to include the NO FOLLOW and NO INDEX attributes in all advertorial links, except those which promote the services, information  or products contained within the page itself.

In 2013  just before Google introduced the HUMMING BIRD algorithm they tried to encourage the use of the REL= AUTHOR and REL = PUBLISHER HTML (Hyper Text Markup Language) attributes. The way that Google went about this was not well reprieved within the online environment, and very limited number folks actually used this extremely powerful SEOT (Search Engine Optimization Tactic)  At this stage of the game, in 2013,  Google was getting quite good at identifying individual digital entities, and they needed a tool to help them identify publishers and authors a lot faster than they were.

The Black Hat Search Engine Optimization crew picked up on this and abused the REL = AUTHOR and REL = PUBLISHER attributes to achieve better rankings for stuff that should not even be indexed in the first place. Google then advised folks that they were no longer making use of these two HTML attributes, and took steps to punish folks who they caught out abusing the REL = AUTHOR and REL = PUBLISHER attributes within the HTML code of links.  These two HTML attributes are however now used extensively to build trust factors between online content and specific contributors to online content, and those who break the trust through making use of BLACK HAT SEOT's are labled as cheaters who deserve to be lower down in the trust table.  The impacts of this are HUGE  If you are not using the REL = tags in all hyperlinks within your HTML code you are losing out on a vast pool of trust factor signals that would enhance your search Engine Optimization in many different ways, from the added author and publisher trust scores to the added tread depth of semantic footprints associated with the NO INDEX and NO FOLLOW attributes

The depth of a semantic footprint is dependent on the digital trust factors associated with the semantic context of each page that is linked to from a specific page (outbound links) as well as the semantic context of all inbound links. The digital trust scores between the in-page content of two linked pages is one of the primary factors that influence the depth a a semantic footprint.  You need to remember that SEMANTIC TRUST is just one element of the many diverse issues that make up digital trust.

Digital entities

Digital entities are a strange mix of all online stuff. Some digital entities are stand alone entities, but most are  actually a collection of other digital entities rolled into a new digital entity as a group.  Each and every HTML page within the online environment is a complex digital entity. some examples of stand alone digital  entities are

·                    PDF documents
·                    images
·                    music files
·                    videos
·                    text documents
·                    social media posts

Most web pages and blog posts are considered to be both stand alone digital entities as well as complex digital entities.  This may sound confusing, but needs to be interpreted from the perspective of a search engine, and not us as humans.  As an example a book is a stand alone entity, but it consists of typed pages that are bound together, which can be separated or torn loose.  When the pages are torn loose the book looses value, and may not make sense to future readers as some information will be missing. It thus follows that the pages need to be joined at the books spine, other wise the book has little value.  In the same manner all the components of a web page can not be seperated from the page, as they may not make sense on their own.

People who can be identified, through their online contributions as authors are also considered to be digital entities, which are a collection of all their identifiable digital contributions which can come from a number of sources, including but not limited to the list below

·                    blog posts
·                    web page copy-writing
·                    social media profiles
·                    social media posts     
·                    forum posts and contributions
·                    comments in social media posts
·                    comments to blog posts
·                    in app consumer education  matters

The various sources of information that link an author to specific content, such as but not limited to the list below help the search engine to build a trust graph of authors, showing their expertise and niche areas of interest, along with trust levels, which are used extensively by Google, and possibly all other search engines as well.

·                    A blog post discussing online content which the author contributed to, with a link to that online content, where the author is listed as a contributor, preferably using the REL = AUTHOR TAG within the HTML code associated with the hyperlink (LINK)
·                    A social media post within the authors profile, discussing the content in question, along with a link to that content.

·                    A social media post by a business page where the author is listed as a manager, a contributor or the owner

·                    A social media post by the authors profile within a group, a community, or a forum discussing the content in question with a link to that content

·                    An article or social media post by a third party which explisitly defines the author as  a contributor to the content in question.

·                    A social media profile page, aweb page or a blog page listing a profile  of the author as an author of online content through the REL = AUTHOR method , where links to blogs, websites and other relevant online content contributions by the author is discussed.


Just as authors have trust graphs and related info stored in a data base by search engines, so to do PUBLISHERS.  These trust graphs for publishers are considerably larger and more complex than the trust graphs for authors, and carry considerably more weight within the Search Engine Optimisation equations.  Publishers and authors are also linked up, and a single publisher may have many diverse points of publication, which include but is not limited to
·                    many websites
·                    numerous blogs
·                    a plethora of social media profiles within different social media platforms

Authors may write for more than one of these different publication points, as well as other publication points for other publishers. This allows search engines to gather more data and have a deeper understanding of the semantic linkages between the different publishers and diverstity of authors.  This understanding is enforced and complemented by the semantic trust that is developed over time between all these groups and many other digital entities.

Digital trust is built up over time where search engines keep track record of many different issues, and use these in complicated algorithyms to develop many individual trust facors which   are later worked on and processed by a final stage  trust algorithym that has feed back loops into  both the early stage search algorithyms and the final stage search algorithym where the search engines SERP's (Search Engine Results Pages) are generated from the search engines data bases.

Digital trust is thus a very important part of the current (Jan 2016) Search Engine Optimisation equation which you as an information provider need to manage and where possible manipualte through careful well managed cross platform marketing. 

cross platform marketing is a form of content marketing, where you market social media  posts,   posted in one platform, in a second platform, so that the orginal content marketing post can aquire larger trust factor signals, and in turn push these larger trust factor signals through to your original online content in your blog or web site.

Example of cross platform marketing.

1) you write a blog post and be sure to use the REL = AUTHOR attribute in a link to your author bio page within the inpage content.
2) you write about your blog post on your FaceBook page with a link to the specific blog post
3) you tweet about your blogpost, but use the link to your Facebook post as the destination URL (Uniform Resource Locator or web address)
4) you write a post in linked in discussing your blog-post, and include a link to
·                    your tweet
·                    your Facebook post and
·                    your blog post
·                    You write a Facebook post discussing your linked-in post with a link to your linked in post.
5) you tweet about your blog post but use the linked in post as the destination URL

Note here that you need to list your social media profiles and all places where you contribute within the online environment in your author Bio Page.  You need to take some time here and do all the home work... be sure to include every where that you have an active social media profile as well as all the blogs and web sites where you are an active contributor.  Your profile page which is accredited with author status through the REL = AUTHOR attribute needs to be well maintained and current at all times, remembering the query freshness issue.

The main purpose of cross platform marketing is to improve your OPSEO or Off Page Search Engine Optimization scores and trust factors within the online environment for all your content.  Cross platform marketing is the best way to grow your online trust factors, so be sure to remain on topic and reply to all comments on your social media posts, as well as comments on your blogs.

Replying to comments within your social media posts and having on-going conversations within the comment streams of other authors or publishers who discuss semantically similar topics to your web sites and blogs is seen in a very favorable light by most search engines. By showing an interest and keeping the conversations active you increase your trust factors within the search space considerably.

These issues of keeping the conversation alive and active within the social media space can only be seen and used by search engines when your profile is public and you post to the public domain.  Most search engines only have permission to see your public profile, how ever if you are a Google User and are logged into your Google account, then you will get a very different approach, as Google will then personalize your SERP (Search Engine Results Page) using your
·                    Google plus profile
·                    G-mail contacts
·                    Google drive documentation
·                    blogger profile and any blogs that you may own or contribute to
·                    Google sites, where you may have created, both public and private
·                    any other Google service that you may use.

These are all used to evaluate your trust factors, with a primary concern for your SEMANTIC TRUST FACTORS which will be used to determine your authority as an author, and your feilds of expertise where you may need some recognition as an expert or not.

Digital trust is a very complex issue, where there are many different parties invloved in supplying trust factor signals, which are interpreted, scored, ranked  and then transferd to a data base for future use by the many different algorthyms which are run to determine a match between a search query and a specific piece of online content.

Links,  both out bound and inbound are the primary sources of all trust factor signals, and as such both sides of the link are evaluated in a number of different ways to determine a host of SEOVI (Search Engine Optimisation Value Indicators) which are then processed to determine a new set of variables where the different areas of digital trust, such as semantic trust, network trust, context trust and many others are carried forward to other algorithyms.
