Troubleshoot a line item that's not being delivered

If one of your line items isn't delivering ads, follow the troubleshooting tips below, or use the Google Publisher Console (GPT only) or debug tool (GAM tags only):


  • Have the order and line item been approved?

  • Have you confirmed the status of your line item? A line item’s status will change from "Ready" to "Delivering" when it has begun delivering valid impressions.

  • Has sufficient time passed for the change to take effect in the server?

    If not, review your line item's flight dates by clicking the Delivery tab, then click the order containing your line item. Your line item's flight dates will appear as the start and end dates.

  • Have you overbooked the line item? If you're attempting to deliver more impressions than you have, not every line item will serve. Learn more about overdelivery and underdelivery.

  • Are the flight dates correct? Make sure that the line item is currently scheduled to be delivered.


Targeting and contending line items

  • Have you properly tagged your pages?

  • Are there any targeting filters or delivery settings (such as frequency capping) that would prevent this line item from delivering?

  • Does the ad tag contain the key-value that the line item is targeting? To review your line item's targeting criteria, click the Inventory tab, then click Targeting.

  • Does another line item conflict? Line items might not serve ads if another line item takes priority or is behind schedule. You can find out what ads are competingby examining the list of "Delivering" line items on the "Delivery" tab.

  • Is the line item ahead of schedule? Line items that are on or ahead of schedule might not always be delivered. You can check the line item's progress when viewing the line item in DFP.

Unexpected changes

  • Did a different user make unexpected changes to the line item? When more than one person has access to your DFP account, it's possible that someone else might have made a change that you didn't know about. You can view the change history to see what changes have been made to the line item.
