I think Google identify content`s meaning much better than ever before using NLP API and Cloud Vision API.
Google’s NLP API takes the content and splits it up into what we understand as “entities”. The Entities are shown in colour with a little number below each one. The numbers are actually relative rankings based on the SALIENCE of the entity within the article itself.
Cloud Vision API reports if picture about medical content or not and show this information in Safebrowsing tab. Medical sites under control of Safebrowsing. Google thinks that content many of them can harm or misinform users.
High E-A-T medical advice should be written or produced by people or organizations with appropriate medical expertise or accreditation.
High E-A-T medical advice or information should be written or produced in a professional styleand should be edited, reviewed, and updated on a regular basis.
I think Google algo takes into account some templates of professional medical style. Freshness is very important thing as well.
High E-A-T information pages on scientific topics should be produced by people or organizations with appropriate scientific expertise and represent well-established scientific consensus on issues where such consensus exists.
Websites or pages without a beneficial purpose, including pages that are created with no attempt to help users, or pages that potentially spread hate, cause harm, or misinform or deceive users, should receive the Lowest rating. E-A-T and other page quality characteristics do not play a role for these pages.
My favorite example from Google search quality evaluator guidelines:
Article titled “Getting Rid Of Toxins After The Holiday Season”
● Low quality MC
● Misleading page title
● Lacking E-A-T
The title of the article is misleading and does not reflect the actual content of the page. The MC does not explain how to get rid of toxins or what the word “toxins” in the headline refers to.
The content also has many problems: the writing quality is poor, and the article includes meaningless statements such as “water therapy is one of the easiest ways of beauty regimen since it will give enough moisture on the skin”. The article fails to cite sources, and there is no evidence of E-A-T.
As you understand the page title is very important for determining relevance. Optimize the content and length of titles, H1 and descriptions.
