Gmail ads are a type of paid ad you can launch, run and manage through Google Ads that appears on the Gmail platform for users’ inboxes.
Gmail ads appear in a format very similar to normal emails, starting out in a collapsed form at the very top of users’ “Promotions” tab. When clicked on, they expand into a full email. They typically contain an image, a specific offer or promotion, and a call to action (CTA).
These ads can target users based on a variety of characteristics, including their demographics and keywords they’ve searched.
Essentially, you can tell Google the type of audience you want to target, and it will display your ads in the Gmail inboxes of users who fit that description. And while the ads themselves work more or less like PPC ads, they’re formatted like regular emails.
