Traffic source approval

A feed provider is responsible to Google, Microsoft or Yahoo for every click that passes through its account. So it does not let partners send visitors from anywhere they like. Before a campaign starts, the arbitrageur declares the traffic source (for example Meta, Taboola or a specific push network) and often the domain, lander and sample creatives. The provider approves, limits or refuses it.

Mainstream sources with strong ad review are usually approved. Sources with a history of bot traffic or forced visits, such as pop traffic, push notification traffic, domain redirect traffic and incentivised traffic, are often refused or capped. Google's own policy pages name "acquiring traffic from non-compliant sources" as a violation that counts towards strikes, and the AdSense Program policies bar traffic from paid-to-click schemes and unwanted software.

Approval is not permanent. Providers watch each source through its Channel ID or Sub ID, and a source whose clicks stop converting for advertisers will be cut. Sending undeclared traffic, or mixing it into an approved channel (traffic blending), is a common reason for feed loss.

Think of it like this

A wholesaler will supply your stall only if it knows which market you sell in. Quietly reselling the goods somewhere it never approved ends the supply.
