For contacts to appear on the Google Ads Insights panel it is necessary that:
The contact acquires UTM tags as follows: utm_source with the value GoogleAds and the utm_content with the ad ID as the value. The URL would appear as follows: https://sprinthub.com/?utm_content=726027236388&utm_source=GoogleAds
In the example below, you can see the contact being correctly identified by a Google campaign, with the information displayed in the UTM Tags tab and recorded in the Activity History.
