Measurement and attribution

Attribution windows: define the time between the ad and the sale

A conversion window affects which purchases can receive advertising credit. Align reporting and commercial terms before comparing results.

An attribution window defines how far after an eligible interaction a purchase can receive credit under a particular measurement rule. Changing that window can change reported conversions without changing the number of orders the store actually received.

Match the definition to the question

Campaign analysis may examine several views of the customer journey. A partnership agreement needs a clearly specified rule for which sales qualify. Those purposes can coexist, but the difference should remain explicit.

Ask which interactions count, how long the window is, how repeat visits are treated, and how competing claims are resolved. If the commercial arrangement is based on ad clicks, do not assume that a report including view-through activity represents the same set of eligible orders.

Consider the product’s buying cycle

A replacement accessory and an expensive, considered purchase can involve different customer journeys. Examine actual behavior and the available evidence before adopting a window simply because it is common in another account.

A longer window is not automatically more accurate, and a shorter window is not automatically more conservative in every analytical sense. Each excludes or includes interactions according to a rule. The team should understand what that rule helps it see and what it leaves uncertain.

Keep comparisons consistent

When performance changes, check whether reporting settings changed too. A comparison across different attribution windows can create an apparent improvement or decline that partly reflects the measurement definition.

Record important settings with the report, especially when presenting findings to people who do not work inside the platform. Consistency is particularly important when comparing channels or discussing changes in investment.

Resolve the edge cases in advance

Walk through a purchase following several visits, an order placed near the end of the window, and a shopper who interacts with multiple campaigns. Agree how the underlying transaction will be identified and reviewed.

At EP4P, the percentage and attribution rules are established before launch, and payment applies to ecommerce sales directly tracked to clicks on our ads. Clear windows make that agreement easier to administer. They also help the team have a more honest discussion about marketing influence without treating every claimed interaction as a separate sale.
