Image extensions are ad extensions that allow you to upload rich, relevant images to complement your existing text ads. With compelling visuals of products or services that enhance the message of your text ad, image extensions can help drive performance for your ads.
- Image extensions perform best when closely relevant to queries within the ad group or campaign.
- Images should convey useful information to the searcher and match the experience that they will find on your landing page.
- Put your important content in the centre 80% of the image.
To ensure that we provide a high-quality consumer ad experience, image extensions must comply with all Google Ads and personalisation policies. In addition, we will review each image extension for compliance with the image extension requirements listed below, which will take priority in the event that there is conflict with the Google Ads and personalisation policies. The image extension requirements are more restrictive than the ads requirements for other platforms and surfaces, meaning disapproved image extensions may continue to run on Google’s other owned and operated properties.
Performance of an image extension may depend on image quality and relevance to the associated keywords and ads in your Google Ads account. Images should highlight the actual product experience and conform to the requirements outlined below.
Requirements for using image extensions:
You should be able to use image extensions in your Google Ads account once your account has generated sufficient history on our platform and has met the following requirements:
- Account has been open for more than 90 days.
- Account has a good history of policy compliance.
- Account is in an eligible vertical or sub-vertical. Sensitive verticals or sub-verticals (for example, sexual content, alcohol, gambling) aren’t eligible for image extensions.
Disclaimer: By opting into image extensions, you confirm and acknowledge that
- You (the advertiser) own all legal rights to publish images and to share those images with Google.
- You hereby instruct Google to publish the shared images on your behalf for advertising purposes
