E-E-A-T is not a score
The framework comes from search quality rater guidelines, where people assess whether a page demonstrates experience, expertise, authoritativeness and trust. It is a description of what a good page looks like, not a metric that ranks pages directly.
That matters practically. There is no tag, no markup and no checklist that adds E-E-A-T. There is only the page, the site around it and what other people say about it.
Generated content is neither helped nor harmed by the framework in itself. A page written with a model can demonstrate all four if it contains real experience and real evidence, and a page written by a person can demonstrate none of them.
So treat the framework as an editorial standard rather than a technical one. It tells you what a reviewer would look for, which is exactly what a writer should supply.
