> In the event an advertiser wants to evaluate the relative performance of 3 campaigns (which they might have purchased from different ad-sellers) I assume that they would NOT issue three separate queries as you’ve shown. This would wind up hitting their differential privacy budget three times for the same set of trigger events. They’d be far better off running a single query with all of the source events from all three campaigns, and all of the trigger events. This would make much better use of their budget, as well as enable “global attribution”, where we can avoid double counting. I think I might be missing something. Is this use-case possible to achieve with IPA: > imagine there's a single advertiser selling a single product, and is running 3 different campaigns for it. They want to use IPA to measure the relative performance of their 3 campaigns. i.e. I want a break-out that says: Campaign1: led to 10 conversions Campaign2: led to 15 conversions Campaign3: led to 150 conversions My thought from the doc was this is accomplished via carefully sending relevant source events, but let me know if / how you think this should be in done in IPA. -- GitHub Notification of comment by csharrison Please view or discuss this issue at https://github.com/patcg/private-measurement/issues/9#issuecomment-1121221709 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
