Why am I seeing a discrepancy between data in Facebook and in Glew?

If you’re seeing a discrepancy between the Facebook performance data you see in the Facebook Ads Manager and in Glew, there could be a few reasons:

  • Attribution window: For Facebook metrics, we use Facebook’s standard attribution model (one-day view, 28-day click). That means Glew will display data for purchases that happened within one day of someone seeing a Facebook ad or within 28 days of someone clicking on a Facebook ad. We used first-purchase attribution throughout most of the rest of the app, meaning that all purchases will be attributed to the channel that originally drove them to purchase from you.
  • Actions: Glew counts Actions taken off your ad, which are counted as action type = “purchase” on your website.
  • Lookback date range: Currently, Glew defaults to a 7-day lookback. If you have orders coming in more than 7 days from the visit, the report may not be picking them up.

If you are looking at the correct attribution window, counting the same action type and still seeing a disparity in your data, please get in touch with us at support@glew.io.
