#EEAT is a vastly complex search engine optimisation Value indicator.
Most folks forget that every link has two sides... yes that is correct, two sides. first is the origin and the other is the destination
These links do many strange things in a host of unthought of places.
Search engines use these kinks in so many different places, but most SEO PRACTITIONERS that I speak to are very ignorant and refuse to think past the end of their noses
Once your online content has been indexed, that is when the fun and games starts.
all search engines use the links within your online content to start mapping out many different issues like
- trust maps,
- entity graphs
- link maps,
- expertise maps,
- expert connectivity status graphs,
- subject matter connectivity graphs
- Subject matter connectivity maps
- and so many more.
There are actually thousands of data bases at play here, where search engines
take a very fine tooth comb and evaluate your content in very serious and devious ways. This is where the #HummingBird algorithm shows its value
They need to establish the purpose, aims, objectives intent and so many
other issues about your online content. It is vital that you remember that Search has evolved, and search engines match your page intent to the intent of the search query. So keywords are not used during the initial search process.
This does not mean that #KeyWords are obsolete, coz they are not.. Keywords are actually vital, and they are used in so
many other areas besides to match to query words.
Many of the data bases that we are talking about here, use both ends of the link and compare both sides to each other and to a third area that holds the imagined contextual issues of your page.
This imagined contextual map changes and grows, as issues within your page unfolds and gets exposed to the many different algorithms that are processed during the vigorous indepth evaluations of your content. Lots of strange and very sneaky things happen coz so many things are happening at the same time in different areas of the page identity and categorising process.
Semantic connectedness issues are also evaluated during this time. The semantic intentions of your content is first processed at this stage, but this is a very fluid issue, coz this changes as the search engine evaluates more and more issues, which are all integrated into these many different data bases that are growing, as the search engine's interpretation of your content evolves with each iteration of the algorithms that evaluate and transcribe your content into machine understandable contextual content within many different data bases
This is a very confusing time, coz so many things are being processed by a vast number of different algorithms, all at the same time. all SEO factors are evaluated and processed at the same time, but by different algorithms. So this is a very busy time.....
This repeats each time your content is revisited to include new backlinks or any updates that may or perhaps may not be re-evaluated.
lots of issues are processed, and most require links to have any positive impacts on your SEOVI (Search engine optimisation value indicators)
these links nay be internal or external.
The two ends of the link are compared in a very large number of different ways, where context and contextual linkages are the key to better understanding your online content, along with the semantic connectedness issues.
On line search is a vastly complex issue where many different Search engine optimisation value indicators are evaluated and taken into account, to give your online content a set of scores that will be used to match your online content to future
search queries. These scores are stored in a wide variety of databases, leaving them ready to be used instantly. This is important, and can be seen if you look at how long your online search took to resolve. this is usually shorter than half a second for most searches, and the number of search results is scary, often being more than one hundred thousand matches.
The amount of preparations that are done to ensure short search times are achieved is incredible, and one thus needs to understand these issues when copy writing is undertaken.
things like link attributes and related issues also need to be included here. All links are valuable, and each link in your content gets the same basic treatment, then some will get extra issues added if the search engine deems it necessary to expand the conversation.
Trust and authority are some of the extended evaluations that need to be properly interpreted. Contributor Expertise and contributor experience is slso an extended evaluation zone.
EEAT or Experience, Expertise, Authority and Trust are all rather strange SEOVI ( Search engine optimisation value indicators) that rely on links to be mapped to the correct issues within your online content.
It thus follows that links and link attributes need very careful deep planning to get the most powerful SEO impacts. 
EEAT or Experience, Expertise, Authority and Trust are all special use search engine optimisation issues that search engines use to evaluate the purpose, aims, objectives and intent of your online content.
There are many issues and different entities involved. Each contributor is evaluated for their personal EEAT, and then the page itself also gets an EEAT SCORE according to the Aims, objectives, purpose and intent of the page in question, as well as the EEAT SCORE of all identifiable contributors to the content in question.
So EEAT is much more complex than you think. New techniques and tactics are constantly being added and this helps to ensure the success of the search engine in question.
