Because ranking factors work in combination rather than as independently scored, additive points, it's misleading to think of SEO as checking off a fixed list of factors one by one — a page can satisfy every commonly-cited on-page best practice and still rank poorly if it doesn't genuinely serve the query's intent better than competing pages, or conversely can rank well despite skipping a 'best practice' if its overall relevance and quality clearly outweighs it. Broad categories consistently confirmed or strongly implied as influential include content quality and relevance, backlink authority, technical crawlability and page experience (including Core Web Vitals), and increasingly, structured entity and E-E-A-T signals — but the exact relative weighting of any specific factor is neither published nor stable over time, which is why chasing any single factor in isolation is a less reliable strategy than broadly strong execution across all of them.
Example
A page technically checks every classic on-page SEO box but still underperforms a competitor's less 'optimized' page — a reminder that ranking factors interact holistically rather than as an independently scored checklist.
