Core Concepts
Safe Page / White Page
In ad cloaking, the safe page (also called the white page) is the compliant, policy-clean content shown to an ad platform's review crawler, bots, and any visitor a filter decides not to trust — while real prospective buyers are routed to the money page instead. Cloaking X calls this a stream's Fallback Page: it's a real HTTP 200 response, not an error, so a reviewer sees a normal, on-topic page rather than anything resembling a block.
