Cloverr is an invite-only traffic filtering and routing service designed to help advertisers distinguish genuine visitors from bots, proxy traffic, advertising moderators, and spy services. It checks each visit in about nine milliseconds and directs suspicious or automated traffic to a White Page, while allowing approved visitors to reach an offer. Decisions are recorded with details such as the verdict and its reasons, helping users review individual visits rather than rely on an unexplained score.

The service evaluates browser and environment characteristics, network and IP reputation signals, automation indicators, and campaign-specific rules. Users can begin in Review mode to observe potential filtering before enabling blocks, then adjust thresholds and create custom allow and block lists for each campaign. Cloverr offers integrations through API, PHP, WordPress, JavaScript Bridge, and Advanced PHP, along with campaign settings and an AI assistant that prepares changes for user approval. It is designed to work alongside traffic sources, trackers, and landing pages, not replace them.
