Tracking & DataAttribution

What is Attribution? Attribution Models and Windows

Also known as: attribution model, attribution window

Short answer

Attribution is how you decide which ad gets credit for a sale when someone saw several ads before buying. Only one sale happened, so an attribution rule decides who is credited.

The simple way to think about it

A buyer sees your video ad on Monday, clicks an image ad on Wednesday, and buys on Thursday. There is one sale. Who earns the credit?

Attribution is the rule that answers that. The rules differ by platform, which is why the numbers differ by platform.

The common models

ModelIts ruleIts weakness
Last clickAll credit to the last clicked adIgnores the ads that built interest
First clickAll credit to the first adIgnores the ad that closed
LinearSplit evenly across all touchesTreats trivial and decisive touches alike
Data-drivenSplit by patterns the system learnedCannot be checked by hand

What to do about it

  1. Pick one model per platform and stop changing it often.
  2. Record the attribution window you use, so month-on-month comparisons are fair.
  3. Never sum conversions across platforms.
  4. Check against MER every month.

Frequently asked questions

What is an attribution window?
An attribution window is the time allowed between seeing or clicking an ad and the conversion, for that conversion to still count. For example, 7 days after a click. Conversions outside the window are not credited to that ad.
Why do platform conversion counts add up to more than my sales?
Because each platform uses its own window and model, and each claims the same sale. Never sum conversions across platforms. Use MER as a sanity check.
Which attribution model is correct?
None is fully correct. A model is only a rule for splitting credit. What matters is choosing one, using it consistently, and checking it against a number that does not depend on attribution, such as MER.
