Questions for the buy side? Put them on the queue in advance here.

[AramZS]

I've set up this issue to provide a thread for anyone with questions for our buy-side guests on the 27th (see more here: #59 ). We'll anticipate live questions at that time as well, but if you can think up questions in advance that would be conducive for more detailed answers.

Hello,
On Criteo side, we would like to present and discuss our “Use cases and principles for Attribution/Measurement proposals” proposal patcg/proposals#14

How do the proposed PETs/Attribution models eventually get incorporated into the bid stream for campaign execution and automated optimization? Today, there isn't a need for browser to talk to publisher in the bid stream because cookies are the acting component (please someone help educate if that's not the case). Today, setting a browser in a DSP is one "filter" that can be made.

Instead of a buyer interacting with a publisher or SSP, would the publisher-side engage with browsers to make the ad call and therefore a buyer would essentially contract with browsers?

How important is it, currently and post-cookie (and with other privacy preserving updates in place), for campaign reporting to include the following for campaign management, optimization and post-campaign analysis use-cases:

• The domains on which impressions appeared?
• The domains on which impressions which converted appeared?
• The time at which impressions appeared (and with what precision: day-part, hour, 10 minutes, minute)?
• The timeliness of impression reporting receipt: real-time, within 5 minutes, an hour, a day of impression appearing?

Is it anticipated the importance of any of this information will change materially post-cookie and with other privacy preserving updates, and if so, how?
Are there alternatives to the impression domain that can satisfy use-cases it is currently employed in and if so, what are they?

How would the ecosystem respond to a directive that "measurement accuracy" is a scarce resource that needs to be shared with DSPs and 3p ad servers / measurers?

How do buyers think about the concerns of users or potential customers? Do buyers care about not bothering the user, are they wary of not violating user's privacy preferences?
