Question: Jacob is curious about single-image ads in a Discovery campaign. What best describes single-image ad layouts?
- They show a brief five-second preview of a company's products and services, just like multi-image carousel ads do.
- They show one collage image comprised of many product image assets.
- They will expand the image that his customers long-press on.
- They allow Google to combine images, headlines, and descriptions into countless ad variations.
Explanation
In Google Ads, single image ads in this format can include up to 20 images, up to 5 headlines, and up to 5 descriptions. That means the ad is built from multiple assets rather than from one locked creative. Google can then assemble those assets into versions that fit different placements and screens across eligible inventory. This makes the format adaptable, which is why it is defined by asset combinations instead of a static image treatment. Google Help+1
Why the other options are incorrect
A) A five-second preview is a video behavior, not the defining layout structure of single image ads. Google Help
B) Google does not define this format as one collage image; the official specs describe separate image assets along with text assets. Google Help
C) Press-and-expand behavior is not the core format definition in the official specifications for single image ads. Google Help
