About key event window

The key event window determines how far back in time an event is eligible for attribution credit. For example, if you have a key event window of 30 days, after a customer clicks on your organic products, any transaction that happens on your website by that customer in the next 30 days will count as a purchase in your Merchant Center reporting. Changes to the key event window only affect how purchases are counted from that point on.

To update the key event window:

  1. In your Merchant Center account, click Settings Tools and setting menu icon [Gear]in the left navigation menu.
  2. Select General.
  3. Click Key event setup tab.
  4. For website purchases,
    • Click on the name of the key event that you would like to change.
    • Select a lookback window of 7, 30, 40 days. 40 days is the recommended lookback window.
  5. For Google analytics conversions, [UA] Update your Attribution project settings [Legacy].
  6. Click Save.
