Tested Results: Google Ads Image Extensions Character Limit

The Google Ads platform rolls out updates to provide new methods for advertisers to display information and entice the user to click to learn more. When these updates occur, Google provides an overview of the update, requirements and expectations, but there are no best practices for using Google’s new tools. Our digital marketing experts stay up-to-date with these changes and go above and beyond to conduct in-house research to guarantee our recommendations are relevant.

In May 2021, Google announced image extensions for all Google Ad accounts. We were suspicious of a decrease in ad character limit and were curious how much ad messaging would be cut off with images taking up more space. These questions led us to look further into finding the correct character count for Google Ad image extensions.

What are image extensions in Google Ads And How to Use Them

Google Ads image extensions allow advertisers to add compatible visuals to enhance existing text ads. This new type of ad extension helps create a more compelling message that looks more like an organic result. To use image extensions, ad accounts must be open for 90 days, have a good history of policy compliance, be in an eligible vertical or sub-vertical, and have active text ads.

There are two types of image extensions: static and dynamic.

  • Static image extensions include images that advertisers manually upload, and they will not change when the ad is displayed, giving the advertiser more control. This type of image extension only shows on mobile at the absolute top position.
  • With dynamic image extensions, the advertiser opts in to allow Google to show an image from the website based on what they deem relevant, leaving the advertiser very little control. Dynamic image extensions show on both mobile and desktop. However, Google typically serves static image extensions over dynamic.

Image Extension Specifications

To best represent products and services, Google allows advertisers to upload up to 20 high-quality images that are relevant to targeted keywords. Images can not include text graphic overlay, logos, too much white space or prohibited content. Uploaded images also cannot be poorly cropped, blurry, distorted or a part of a collage. Google accepts two image sizes to use in image extensions: square and landscape.

  • Recommended Square Image Specifications: 1200x1200
  • Recommended Landscape Image Specifications: 1200x628

When an image extension appears on Google search results page, the headlines, descriptions, URL and image are shown.

So how many characters can image extensions be?

After evaluating our research, the Blue Compass digital marketing experts determined the character count for image extensions Google Ads headlines is 60 and 135 characters for descriptions. For reference, the maximum character length for Google Ads is 180.

Why does this matter?
When words are cut off in Google Ads image extensions, it compromises important information the viewer needs to make an educated decision to click or not. It is best to include a call-to-action at the end of ad copy that allows the advertiser to tell the viewer exactly what to do next. However, if the character count is too long, the call-to-action will likely be cut off.
