In SEO, content quality describes how well a page serves what the searcher is looking for. That includes whether it is accurate, complete, clear and trustworthy. Google does not publish a single score for it (assessment).
How is content quality assessed?
Google’s documentation on helpful content gives questions rather than a formula. Examples are whether the content offers original information, reporting, research or analysis, whether it describes the topic in a substantial and complete way, and whether it is written or reviewed by someone who demonstrably knows the topic. Google also describes E-E-A-T (experience, expertise, authoritativeness and trustworthiness) and states that of these, trust is most important.
The Search Quality Rater Guidelines, which Google’s raters use to evaluate search results, say the same about trust. They describe it as the most important member of the E-E-A-T family, because untrustworthy pages have low E-E-A-T however expert they appear.
There is no required length. Google says it has no preferred word count.
Example (fictional)
Two pages explain the canonical tag. Page A summarizes three other articles. Page B names its sources and date, shows a tested code example and names the author. Page B answers Google’s questions about originality, expertise and transparency better.
FAQ
How long should a text be? Google names no preferred word count. The length follows from the question the text answers.
