Definition
GPT sites broaden the PTC model to include surveys, offer walls, app installs, and micro-tasks, usually paying more per action than a straight click-to-view PTC ad.
Why it matters to marketers
As an advertiser, GPT offer walls can drive volume quickly, but the audience is largely task-completers chasing payouts rather than people evaluating your offer — expect low genuine interest even when click numbers look strong. Budget GPT traffic as a volume/cost test, not a quality channel.
