Guidelines for expandable creatives

Expandable creatives expand in size when someone clicks or hovers their mouse over an expand button in the ad. You can serve expandable creatives by assigning them to display line items. Note that publishers can decide whether to allow them on their inventory. Expandable creatives will only serve on inventory that allows expandable ads.

Display & Video 360 doesn't support direct upload of expandable creatives, but you can sync them from Campaign Manager 360 or serve them from a supported third-party ad server then add them as third-party display ad tags.

When you add an expandable third-party display ad tag, you must set an expanding direction before it can serve. If the creative is built with Studio and served through Campaign Manager 360, the expanding direction is automatically detected.

Expandable creatives require manual review, which typically takes about 24 business hours.

Content requirements

To run on Display & Video 360, all creatives must follow the creative content and policy guidelines.

The table below lists the most common dimensions, but other dimensions and expansion directions are supported based on available inventory. To check the dimensions of all available expandable inventory that matches your targeting, use an Inventory Availability report.
