Overview

We are in the middle of our live testing with the PAAPI, one of the challenges we have is to implement diversity logic.

Unlike display advertising, native advertising has several parts: title, description, image URL, and sometimes also a call to action.
Diversity is basically a filtering mechanism that enforces limits on the number of similar content that are coming from the same advertiser and has similarity in the assets details (e.g. title, description, thumbnail url, campaign id, item id) in order to create better user experience for our Publishers.

We are experiencing a challenge when trying to implement such logic into our framework using PAAPI. We have many auctions happening on the single page for a specific user, sometimes it can get to hundreds of auctions. Due to so many auctions we are performing those auctions in parallel else we won't manage to complete them all within a limited timeframe. In such a case we don't see a way to implement such diversity logic.

Few directions we imagined that might be possible are:

• Creating some kind of lock mechanism during ScoreAd (or other) to allow sync between parallel running auctions on the same page for a specific user.

• Perform an auction that returns a list of ads.

Can you please advise?
