Attribution

Attribution is the process that ties a conversion back to the specific traffic source, creative, and click that caused it. Last-click is the most common model within a defined attribution window, though multi-touch models exist too.

How an attribution window works

The attribution window is the period during which a conversion still counts toward a given click, commonly 24 hours to 7 days after the click. A longer window credits more conversions to a source, but makes the click-to-result link less trustworthy, especially if a user was exposed to ads from more than one source.

Attribution in a PWA funnel

In PWA arbitrage, attribution rides on a click ID that has to survive the whole chain intact: tracker, prelander, PWA, in-app event, postback back to the ad platform. Any break in that chain — a redirect that drops parameters, for instance — breaks attribution, and the platform loses track of which creative actually worked. APEX's postback setup is built to carry the click ID through every stage of the PWA funnel.

FAQ

What attribution window is typical in arbitrage?
Windows of 24 hours to 7 days after the click are the most common, with the exact value set by the ad platform or tracker. Too short a window misses delayed conversions; too long a window weakens the link to a specific source.
What usually breaks attribution in a PWA funnel?
Most often it's a lost or truncated click ID somewhere in the chain — a redirect that drops parameters, a cached prelander, or a misconfigured postback. Verifying the click ID survives from click to final event is basic hygiene before scaling a campaign.
