Where these numbers come from.
Every statistic on this page is computed from the SearchScore audit corpus: 850,000+ websites audited with the same automated pipeline that powers the free scan on this site. Each audit fetches the live page, robots.txt, llms.txt and sitemap, checks external authority and review signals, and scores the site against 250+ signals across 8 weighted GEO categories. No sites are excluded for being too small or too large, and no curation is applied.
The full measurement approach, including how each signal is collected and verified, is documented on the methodology page. The quarterly index built from the same corpus, with tier distributions and category averages, is the State of AI Visibility Index (SAVI).
