SEO Tools
69,261 of the 1,000,000 top sites in our Tranco top-1M census run Yoast SEO (6.9%). A WordPress plugin for managing on-page SEO — meta tags, sitemaps, and readability analysis. Detection is homepage-level HTML/header fingerprinting, so a site can run Yoast SEO on other pages without it showing here.
