AppNexus audits creatives based on general exchange standards, and conducts a secondary audit based on Microsoft standards.
Technical requirements
- Duration of animated ads must be 30 seconds or less, or 15 seconds or less for US inventory.
When targeting only AppNexus, don't assign responsive creatives synced from Campaign Manager. There's currently an issue where only the smallest supported responsive size syncs over, which can result in these creatives being ineligible to serve in deals. AppNexus is working to resolve this issue.
