Google today announced the release of full-screen inline ads to all AdSense publishers. Full-screen inline ads are full-screen banner ads that appear inline with your content as a user scrolls the page.
According to Google, Full-screen inline ads appear below the fold in both Auto ads placements and responsive ad units.
Google says publishers don’t need to take any action to have full-screen inline ads on their websites, as these ads will automatically appear in Auto ads placements and responsive ad units.
