What is it?
When an ad has been in a reader's view for more than 30 seconds, Journey will automatically re-run the auction and fill that slot with a new impression. The longer your readers stay on the page, the more you earn, without any extra ad placements or changes on your end.
How do I optimize my site for auto-refresh?
All of your ad units will refresh while in view, but the adhesion ad and sticky sidebar ad will see the biggest benefit from auto-refresh. These units stay visible as readers scroll through your content, giving them more time in view and more opportunities to refresh.
The best thing you can do to maximize auto-refresh revenue is create engaging, longer-form content that keeps readers on the page. The more time they spend scrolling and reading, the more refreshes happen in the background — and the more you earn from every single pageview.
