Data Studies

# SEO Data Studies

Studies on how Google ranks, displays and indexes pages: title and meta description rewrites, ranking churn, search features, schema markup, backlinks and on-page basics. The data comes from Google US search results on desktop and mobile, the websites behind US Google Business Profiles across dozens of industries, homepage code and Google Lighthouse results from the public HTTP Archive crawl, site popularity from Google's Chrome UX Report, and backlink records for small business websites. Each study lists its sample and method, so you can judge how far the findings apply to your own site.
