Create an order and Ad Exchange line item for programmatic native

Once you have your native styles defined for a native ad format, you create an order and Ad Exchange line item as you normally would. The native line item trafficking workflow is completely sizeless. An Ad Exchange native line item will deliver to all sizes on your Ad Exchange-eligible native styles.

We recommend setting up one broadly targeted Ad Exchange native line item (possibly including banner sizes). A single Ad Exchange line item can deliver to many native styles. Running multiple competing Ad Exchange line items may reduce yield. You can set up granular targeting in the native styles to manage different native layouts on different site or app sections.

The differences for native ads are described below.

  1. Create an order.
    There are no special native settings at the order level.
  2. Create an Ad Exchange line item.
    1. Next to Inventory sizes, click in the box and select Native (Native) from the drop-down.
      To maximize performance, we recommend you also include some banner sizes to compete with native ads.
    2. In the “Add targeting” section, target the line item to any ad units and/or key-values for which you configured native styles.
    3. In the “Creatives” section, select Automatically generate creative.

Change the types of ads that will deliver

You can update creative sizes to determine whether Ad Exchange delivers mixed native and banner, native-only, or banner-only ads. The size-related setting you need to update depends on whether you have set up an association with a size override, as the following table explains.

You want to deliver If there’s no association with a size override If there is an association with a size override
Both native and banner ads (Recommended for optimal performance) Not possible Set the “Size overrides” field to a value of both Native and the banner size, and select the "override" checkbox.
Only native ads (Not recommended — performance may suffer) Set the “Target ad unit size” field to a value of Native only. Set the “Size overrides” field to a value of Native only, and select the "override" checkbox.
Only banner ads Set the “Target ad unit size” field to the banner size only. Set the “Size overrides” field to the banner size only, and select the "override" checkbox.

Example

A 300x250 ad request is eligible for Ad Exchange native ads when there’s a valid native style with the 300x250 size (note that the targeting on both the Ad Exchange line item and native style must match the ad request):

  • If the matching Ad Exchange creative only has the Native size, only native ads will serve (using the 300x250 native style).
  • If the matching Ad Exchange creative has both the Native size and 300x250 (in the “Size overrides” field of the association), either native ads (using the 300x250 native style) or 300x250 banner ads may serve.

Here’s an example of backfill creative settings that enable native to compete with 300x250 and 300x600 banner ads:
