Tracking
Tracker
The system that attributes ad clicks to conversions.
A tracker is the technical layer that ties ad-network clicks to downstream conversions. Functions: assign a unique click ID, redirect to the offer with that ID baked in, accept a server-side postback or pixel fire on conversion, attribute back to source/campaign/creative/landing page, and report. Self-hosted (Binom, FunnelFlux) vs cloud (Voluum, BeMob, RedTrack, ClickFlare). Most beginners over-buy.
Example
Click → tracker URL with {click_id} → offer URL with click_id appended → conversion fires → tracker postback notified → attributed back to creative #34 on Taboola campaign 1812.
