These also come as high impact ads, but we still need to host the material in our ad server.

Test the overlay with your campaign information using our Political Ad Preview Tool.
The overlay is anchored to the bottom of the ad and spans the full width of the creative.
The overlay height is not fixed. It adjusts automatically to fit the required disclosure text. Height will vary depending on the following factors:
Advertiser Legal Name The full legal name of the advertiser must be displayed. Longer names will cause the overlay to grow vertically.
Election Name and/or Date The name of the election and election date associated with the campaign is.
PII-based Targeting Disclosure If Personally Identifiable Information is used for audience targeting, an additional disclosure line is required. This adds to the overall height of the overlay.
Controller (if different from Sponsor) If the Controlling Entity is a separate legal entity from the Sponsor, the label will also display "Controller: [Entity Name]" in addition to the Sponsor's name. This adds more text to the label, which can increase the overlay height further.
Minor variations in overlay height may occur across browsers due to differences in font rendering, line-height calculation, and text scaling. Creatives should account for this by maintaining a conservative safe zone that accommodates slight height fluctuations.
To test the overlay with your own campaign details, use the interactive preview tool below. You can enter the advertiser name, election name/date, and toggle PII targeting to see how the overlay renders across different configurations and ad sizes.
