E-A-T and YMYL are concepts, and numerous algorithms and signals are used to see if content matches.

Google has clarified some of the confusion around E-A-T and whether or not it is an explicit ranking factor. E-A-T stands for Expertise, Authority and Trust and is the shorthand used by Google in its Search Quality Evaluator Guidelines.

Speaking at a Pubcon 19 Q&A in Las Vegas last week, Google’s Gary Illyes said there was no internal E-A-T or YMYL (Your Money, Your LIfe) score, rather these were concepts that allowed humans to “dumb down alogorithms”.

Illyes said Google has a collection of millions of 'baby algorithms' that work together to produce a ranking score.

So E-A-T is not an explicit, directly measurable ranking factor, such as for example, page speed. However, many tiny algorithms and signals measure the component parts of E-A-T or YMYL and contribute to ranking scores.

In a follow up discussion on Twitter, Google's Danny Sullivan reiterated:

So, while it’s clear that Google doesn’t allocate a single score for E-A-T, it does affect rankings and Google’s advice to work on these areas for your site remains unchanged.
