Length is not a ranking factor: "Are you writing to a particular word count because you've heard or read that Google has a preferred word count? (No, we don't.)" What Google confirms is a preference for helpful, people-first content, part of its core ranking systems since March 2024: original information, clear sourcing, visible expertise and no easily verified errors. Topics that affect health or finances ("Your Money or Your Life") get "even more weight" on E-E-A-T (Ranking Systems).
Generated content is judged by value, not by tool. Generative AI "can be particularly useful when researching a topic", but the scaled content abuse policy covers many low-value pages made to manipulate rankings "no matter how it's created". Quality raters' "ratings don't directly influence ranking." Moderate user comments and mark their links rel="ugc" (nofollow, sponsored and ugc).
