If by comparing Google Ads data with offline data you find a difference in the number of sign-ups for ads between the two sources, and you believe the issue lies with when a conversion was counted, what’s the likely source of that data discrepancy?

  • It’s probably due to the fact that Google Ads reports conversions against the date/time of the click that led to the conversion. Depending on the other data source, it might use the date/time of the conversion itself.
  • It’s probably due to the fact that Google Ads reports clicks against the date/time of the event that led to the conversion. Depending on the other data source, it might use the click of the conversion itself.
  • It’s probably due to the fact that Google Ads reports views against the device type of the view that didn’t lead to a conversion. Depending on the other data source, it might use the date/time of the conversion itself.
  • It’s probably due to the fact that Google Ads reports conversions against a unique ID of the event that led to the click. Depending on the other data source, it might use the click of the conversion itself.
