CAPTCHA & Bot Protection
90,376 of the 1,000,000 top sites in our Tranco top-1M census run reCAPTCHA (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.
