Social Media & Sharing
3,137 of the 1,000,000 top sites in our Tranco top-1M census run AddThis (0.3%). A universal social share and follow button widget (Oracle's, now Yieldbird's, competitor to AddToAny). Detection is homepage-level HTML/header fingerprinting, so a site can run AddThis on other pages without it showing here.
