Before you begin, ensure that your video ad formats and dimensions are properly configured. A mismatch between the ad format and the ad serving system can lead to errors and poor ad performance.

1. Verify Video Ad Formats and Dimensions

  • Check the video ad formats and dimensions against DV360’s supported formats.
  • For example, if you are using DV360’s supported formats for YouTube ads, make sure your video is in MP4 format with a resolution of 720p or higher.

  • Track and analyze the load times of your video ads.
  • Set up alerts or notifications for any load times that exceed 5 seconds.
  • Identify and address any issues that lead to long load times.
  • For example, if your ads are being blocked by IAS or DV due to technical issues, address these issues by ensuring your ads meet the specified requirements.

3. Review Block Rates and Block Reasons

  • Use the DV360 Performance Report to review your block rates and block reasons.
  • In the DV360 UI, navigate to the "Performance" tab and filter by "Block Rate."
  • Identify the most common block reasons and address them accordingly.
  • Common block reasons include technical issues, ad quality concerns, and ad size issues.
  • Ensure your ads are not blocked due to technical issues or ad quality concerns.
  • For instance, if your ads are being blocked due to ad size issues, ensure that your ads are correctly sized and dimensioned for the ad serving environment.

4. Optimize for CTV and OTT Ad Formats

  • Use the DV360 Floodlight feature to track and optimize CTV and OTT ad formats.
