Criteriads is the trading brand of TheMediaFlow Ltd, a search arbitrage and performance marketing firm operating since 2008. The company works across the US, UK, and international markets, connecting compliant traffic acquisition with search monetisation and lead generation. It buys traffic through official advertising networks, including Google, Meta, Microsoft, Taboola, and MGID, then filters, scores, and routes it to suitable partners and feeds.

Criteriads operates RSoC (Related Search on Content), Bing, and Yahoo search feeds, as well as direct feed partnerships. Its services include revenue-share arrangements for traffic buyers and feed operators, compliant traffic sourcing for feed owners, and exclusive CPA or CPL lead generation. Lead-generation campaigns cover utilities, finance, insurance, legal, and home services; clients pay for qualified leads under agreed criteria, while Criteriads carries the traffic acquisition cost and risk.

The company emphasizes approved traffic sources and states that it excludes bots, incentivised clicks, and other non-compliant sources. Partners can also access a reporting dashboard and API for performance monitoring and data integration.
