If I am running Proximity Campaigns, will they be affected by GDPR? Is there anything I need to set up in the campaign configuration or anything I should have into account for reporting?

Unless a user has provided consent to the publisher where (s)he is about to see an ad to share his/her precise location (as per TCF 2.0), we will automatically anonymize the accurate user location (lat:long) if we receive it, by considering only the first two decimal digits.

In many cases, the ad exchanges themselves will not send accurate locations in the bid request unless they have user consent. This will certainly affect reach and the information you can retrieve from your campaign and its performance:

You will have less inventory available for campaigns targeting user location with "high accuracy", and you can use "medium accuracy" to increase reach to all those bid requests where the reason for low precision (two decimal digits) is that the users have not provided specific opt-in to share the precise location. You can see here more information on location precision settings.
You should also take the following into account:
- The location information, user identifier, and IP address will be anonymized in your session-level data files and in any macros your ads use. You will not be able to retrieve the accurate location where an ad was served to a user who has not provided consent.
- If your campaign is enriching audiences through the “retargeting” functionality, any users who have not provided consent shall not be added to audiences. You will not be able to build user profiles based on the location where users have seen ads unless they have provided consent.
- Users who have not provided consent will not be tracked as visits by footfall measurement tools.
- You can target your campaigns, or a strategy within your campaign to exclude users who have not provided consent if you wish, using the check enabled for this purpose, but please be aware that the reach of your campaign will suffer. You can always test such settings within a strategy, and monitor volumes.
