When creating or editing a line item, use the Display creatives line item setting to set how many assigned creatives can be displayed on a given page.
- Only one: Only one creative associated with this line item appears per page. Once the ad server has served that creative, it doesn't serve any other creatives from this line item. This option is useful if your creatives are similar to one another.
- One or more: Multiple creatives associated with this line item can appear together on a page. Any number of creatives can serve to a user on a single page load: just one, a subset of the creatives, or all creatives. This is the default selection.
Display a line item's creatives together
You can also choose to display a line item's creatives together as a set, or roadblock. Only use these creative display options for line items with multiple active creatives. These line items do not compete with Ad Exchange in dynamic allocation and are only delivered if eligible for the first matching ad slot on a page. Learn more about roadblocks
- As many as possible: Prioritizes creatives associated with this line item to appear together on a page.
- All: All creatives associated with this line item appear together on a page, or the line item cannot serve. This setting requires Google Publisher Tags using single-request mode. If another tag type requests this line item or if creative-level targeting is applied to any of the line item's creatives, the "As many as possible" setting is used.
