Google will soon add dynamic image extensions to ads. These will appear alongside the
fleet of other ad extensions available, such as structured snippet, sitelink, callout,
message, and most recently lead-form extensions.
The feature is in beta with no official release date as of February 2020, but it is quietly
becoming available to some advertisers.
The new extension will allow advertisers to include images in their ads, which look
similar to images included in organic search results. The extension is dynamic, so users
cannot upload their own images. Google will use machine learning to select relevant
According to a Google report, early testing results show the dynamic image extension
has boosted click-through rates by up to 5%. The extension can also help increase ad
relevance and boost quality scores. This is important because quality scores determine
ad rank. Ads with lower quality scores show less often and sometimes cost more.
