Similar-sized ads and ad slot expansion
Occasionally, we substitute a text ad or similar-sized display ad to appear within the ad slot. When this happens, the size of the similar ad is modified (using advanced imaging techniques) if needed and then served in the ad slot.
The new ad size does not necessarily match the full width or height of the ad slot. You can control which creative sizes fill your ad slots using ad contraction.
Some ad slots expand automatically to the maximum width allowed on a device. Ad slot expansion currently applies to backfill display and out-stream video ad slots on mobile web. If needed, you can turn off ad slot expansion.
