Line items

Run line items at specific hours or days

Add dayparting to your line item delivery
With day and time targeting, you can set your line items to run only during specific hours or days, or as little as 15 minutes per week. For example, you might set line items to run only on Tuesdays, or from 3 to 6 pm daily.

Set day and time targeting for a line item

Before you choose your day and time settings, you may wish to run an hourly report to see what times of the day your ads receive the most traffic. A report helps determine if you're setting day and time settings to time intervals where you get higher or lower traffic.

When you run a forecast for a line item, the forecasting simulation takes into account the time period during which the line item is eligible to serve and the amount of traffic expected during that time period. Learn more

  1. Sign in to Google Ad Manager.

  2. Navigate to Delivery and then Orders.

  3. Create a new line item or find a line item.

  4. Under "Adjust delivery," select Set days and times.

  5. Select day and time settings.

  6. Set day and time to either "Publisher's time zone" or "User's time zone".

    Publisher time zone is based on the network time zone set when your Ad Manager network was created. Ensure you follow best practice if you're also applying geographic targeting to line items. Learn more

Best practice with geographic targeting

If a line item targets specific geo locations, particularly places outside your network's normal traffic, best practice suggests that you select Publisher's time zone. Pacing does not take into account geo targeting and, as a result, you may experience unexpected delivery issues. 

Convert the your publisher time zone to the desired time for the location you're targeting.

For instance, suppose you publisher time zone were set to "America/New York" (Eastern Time). Suppose also that you apply geo targeting for California to a line item, which is in Pacific Time—a three-hour difference, New York being three hours ahead of Los Angeles. You want to serve ads to California users between 6 pm and 8 pm in Pacific time. In this scenario, select Publisher's time zone and set day and time settings to 9 pm to 11 pm, which is equivalent to 6 pm and 8 pm in Pacific time.


Ads pace impression delivery according to the schedule you set, ending delivery at the defined hour. You may, however, notice recorded clicks for up to an hour after a scheduled delivery period ends. Rest assured that these clicks aren't errors, but occurred during the scheduled period.

Reports show all impressions in the publisher's time zone. If day and time were set to "User's time zone", reports reflect delivery in publisher's time zone. For example, supposed the publisher time zone is New York, NY (Eastern time) and day and time were set to show from 6 pm to 9 pm in the user's time zone. Users based in Los Angeles (Pacific time) would see ad from that interval based on their local time. However, reports would show impressions for these users between 9 pm and midnight Easter time.
