The Visits metric provides the actual measurable visit count to points of interest measured via our Blueprints technology. We define a Visit as a user visiting the "drive-to" / brand store location within 14 days of a GroundTruth ad exposure.
Visits take two full days to reflect in Ads Manager. For example, on August 30, you will see Visits that occurred on August 28. The 14-day lookback window does not include the 48 hours it takes for data processing and reporting. This means that the overall lookback window will be 14 days plus an additional 2 days to process the data and show it in Ads Manager.
GroundTruth uses a last-touch attribution methodology to attribute visits to impressions. This means that the latest ad impression seen by a user before a visit will be given credit for the visit.
