Question: What should you do if none of the creatives associated with a line item match the ad size requirements in the request?
- Add creatives that match the ad size and type for that deal for the line item
- Add a custom audience to the line item
- Remove all creatives from the line item
Explanation
A deal request can only be served when the line item has an eligible creative that matches the required ad size and ad type. If no associated creative matches the request, Amazon DSP cannot bid with a valid ad. Adding compatible creatives increases eligibility for the deal’s available impressions. This resolves the creative-size mismatch without changing audience or supply settings.
Why the other options are incorrect
Custom audience is incorrect because audience changes do not fix missing creative size eligibility.
Remove all creatives is incorrect because removing creatives leaves the line item with no valid ad to serve.
