51,718 of the 965,200 top sites in our Tranco top-1M census run Cloudflare Bot Management (5.4%). Cloudflare's product for detecting and mitigating automated bot traffic on a site. Detection is homepage-level HTML/header fingerprinting, so a site can run Cloudflare Bot Management on other pages without it showing here.
