Publisher Discovery

Publisher Discovery is the long-established intelligence tool in this space. It crawls affiliate links across the web and maps which sites promote which advertisers on which networks, giving you a database of about 3.5 million affiliate websites linked to 600,000 advertisers across 400 networks, with social and email contact details attached.

The core use is competitive: enter a rival advertiser and see every affiliate sending them traffic, then filter for the ones you do not yet have. Partner overlap analysis shows shared and missing affiliates between programs, AI tools rank prospects, and automated outreach runs from the platform. Because it works at the network level, it is as useful to affiliate networks and OPMs benchmarking a whole vertical as it is to a single merchant. Verticals with the deepest coverage include retail, travel, finance, dating, telecom and gaming.

Pricing is not laid out on the site in a way that renders for automated tools, so the figures here come from software directories: plans start at about £99 a month, the standard plan is around £500 a month (roughly $625) with additional seats at about £150 a month, and an annual option lists at $116 a month. A free trial lets you examine the main advertisers in your market before paying. Confirm current numbers on a demo.

For pure competitor affiliate mining, Publisher Discovery has the largest map. AffiliateFinder.ai is cheaper and handles the emailing; Publisher Discovery is stronger on market-wide analysis.
