Advertising & Marketing
1,780 of the 1,000,000 top sites in our Tranco top-1M census run Magnite (Rubicon Project) (0.2%). An advertising exchange and supply-side platform connecting publishers with ad buyers for programmatic ad sales. Detection is homepage-level HTML/header fingerprinting, so a site can run Magnite (Rubicon Project) on other pages without it showing here.
