Google AdWords Learning Center

AdWords image ads are graphic ads that can be static (motionless) or animated. These ads appear on select content sites (not search sites) in the Google Network which have opted in to the image ads program.

Image ads combine two features — graphics and AdWords targeting technology. This gives advertisers the power of pictures along with the precision of matching ads to related content sites.

Image ads are available for campaigns that use keyword and/or placement targeting. Since image ads only run in the content network, campaigns using keyword targeting only must be opted into the content network in order for image ads to run. To learn how, visit the Edit Campaign Settings topic.

When you load your images via your Ad Variations tab, try to provide descriptive image names so you can better manage your account. Include the following in your image name:

An image description
The campaign or ad group name

Static image ads can be formatted in .gif, .jpg and .png. Animated image ads can be formatted in .gif or Flash. Image ads should clearly and accurately reflect your site and emphasize unique benefits of your product or service.

Both types can be in the following sizes:

250 x 250 Square
200 x 200 Small Square
468 x 60 Banner
728 x 90 Leaderboard
300 x 250 Inline Rectangle
336 x 280 Large Rectangle
120 x 600 Skyscraper
160 x 600 Wide Skyscraper
