As of Today, You Can Tell Google to Stop Showing Images of Underage People When you Search
New Google safety features allow minors to request the removal of their own images from Google search results, which was previously impossible for them to do on their own. New restrictions on ad targeting of minors were announced in August, but the feature is now widely available.
This help page has all the information needed to get started with the removal process. Search terms that bring up these images, the names and ages of minors, and information about the person acting on their behalf — such as a parent or guardian — will be required from applicants.
