OVERLAY AD
An ad that floats over web content, graphics, or videos. Ad-blocking software doesn’t work on it. These ads can begin as a standard, scalable ad unit but hovering over the ad may expand it, while the page behind it dims, increasing emphasis on the ad. Advertisers pay for the number of times the ad is expanded and track these engagements.
