CAPTCHA & Bot Protection
927 of the 1,000,000 top sites in our Tranco top-1M census run Yandex SmartCaptcha (0.1%). Yandex's CAPTCHA challenge product for filtering bot traffic. Detection is homepage-level HTML/header fingerprinting, so a site can run Yandex SmartCaptcha on other pages without it showing here.
