This is a structured SEO audit framework that walks through five layers: technical foundation, on-page optimization, content quality, link profile, and competitive positioning. It includes detailed checklists for crawlability, indexability, Core Web Vitals, and a scoring rubric that weights title tags at 15%, content quality at 25%, and six other factors. The rubric is opinionated (keyword density over 3% gets a zero for stuffing) and includes specific benchmarks like 1,500+ words for informational content. It's thorough but prescriptive, so if you follow a different SEO philosophy you'll want to adapt the scoring criteria. Best for comprehensive site audits rather than quick spot checks.
