Fingerprint deduplication
Each click is fingerprinted from device and network signals. Duplicate and repeat clicks are dropped before the redirect, so one user is never counted, or paid for, twice.

average invalid traffic in affiliate, against about 15% in programmatic and native.
Our answer: filtering happens before the click ever reaches your offer.
Technology
Traffic Engine: the filter between raw traffic and your offer.
Built in-house by our engineering team. Traffic Engine sits between every traffic source and every offer we promote. It decides which clicks pass, logs why the others did not, and records conversions server-to-server.
Automated blacklisting
Sources, placements and sub-IDs are scored continuously. Any that breach quality thresholds are blacklisted automatically and stay excluded across campaigns.
S2S postback & attribution
Conversions are recorded server-to-server, not by browser pixels alone. Works with major trackers and affiliate networks. Offer lifecycle management stops traffic to capped, paused or expired offers.
Transparent reporting
Real-time reporting by source, placement, sub-ID and GEO. Source and placement breakdowns are available to partners on request.
