15,494 of the 1,000,000 top sites in our Tranco top-1M census run reCAPTCHA v3 (1.5%). Google's bot-detection service that scores traffic in the background without user interaction to block automated abuse. Detection is homepage-level HTML/header fingerprinting, so a site can run reCAPTCHA v3 on other pages without it showing here.
