CAPTCHA & Bot Protection
56,649 of the 965,200 top sites in our Tranco top-1M census run reCAPTCHA (5.9%). Google's CAPTCHA/bot-scoring widget, the most widely deployed CAPTCHA by far. Detection is homepage-level HTML/header fingerprinting, so a site can run reCAPTCHA on other pages without it showing here.
