What should you do if none of the creatives associated with a line item match the ad size requirements in the request?
- Add a custom audience to the line item
- Remove all creatives from the line item
- Add creatives that match the ad size and type for that deal for the line item
Explanation:
The correct answer is **Add creatives that match the ad size and type for that deal for the line item** because when none of the creatives associated with a line item match the ad size requirements in the request, the appropriate action is to upload or associate new creatives that meet the required specifications. This ensures that the line item can deliver as intended, with ads that fit the necessary dimensions and format for the campaign’s target placements. Matching the ad size and type to the deal ensures the campaign runs smoothly, avoiding delivery issues and maximizing the effectiveness of the ad placements. Removing creatives or adding a custom audience does not resolve the issue of mismatched ad sizes and would not ensure compliance with the required specifications.
