What does Google actually read as a “quality” signal it can measure?

Google does not publish a list of quality signals or their weights, so any precise answer is a guess. What it does publish is the kind of information its systems use and the questions it asks about content. Its ranking systems guide says its automated systems look at many factors and signals; its How Search Works pages name the main areas, including the meaning of the query, the relevance and quality of content, and usability; and its guidance on helpful content sets out the questions that describe what its systems aim to reward.
What Google has documented
| Area | What Google says it uses or asks |
|---|---|
| Relevance | Whether content matches the query, including through systems that understand meaning and synonyms |
| Links | Link analysis systems, including PageRank, that use how pages link to each other |
| Interaction | Data on how people interact with results, pooled and anonymized, to help judge relevance |
| Content quality | Self-assessment questions about originality, expertise, completeness and whether content was made for people; these are questions for site owners, not a documented measurement or score |
| Trust on sensitive topics | Extra weight for content with strong E-E-A-T on topics that affect health, finances or safety |
| Page experience | Core Web Vitals and other aspects of using the page, which Google treats as one consideration among several |
| Spam | Systems that detect practices in its spam policies |
None of these is a single “quality score”. They are areas from which Google’s systems form a judgment, and Google does not say how they combine.
What to do with that
Treat the documented areas as things to improve, not a formula to hit. Make the page answer the search directly and completely, earn links from relevant sites by being worth citing, show who is behind the content and why they know the subject, keep the page usable, and stay clear of the practices the spam policies describe. A page that does those things is the kind Google’s systems are built to find, whatever the weights are.
What to avoid
Scores from SEO tools that claim to measure “quality” or E-E-A-T directly are their makers’ estimates; whether the EEAT score is a real ranking factor explains why. Improve the page against Google’s own questions, and judge the result by how it performs for its searches.
