Measures a website's readiness for generative search, answer engines, AI citations, and traditional search.
This site's takeaway scores: SEO 94/100 (grade A) and AIO 88/100 (grade B), from 9 measured visibility categories. Strongest area: Search visibility (100/100); weakest: AI & answer engines (77/100). Strong-ranking sites meet an 85-point profile on these same checks — that is the yardstick for both scores.
SEO: meets the strong-ranking profile. AIO: meets the strong-ranking profile. The 85-point benchmark is the score a site meeting the practices that consistently strong-ranking sites follow would earn on these same checks: a measured yardstick, not live competitor rankings.
Each category is a weighted set of measured checks; unmeasurable categories are excluded from the grade, not guessed.
Not measurable on this site, excluded rather than guessed: Local search.
Each score is built from weighted categories; the contribution column shows exactly how many points each category adds to the total (weights renormalize over what was measurable). Categories reuse the same underlying checks; nothing is double-crawled.

Re-checks verify your recommendations against a fresh crawl. Results in search engines and external data typically take longer to move than on-site fixes.
