Interstitial ads volume and average bid by GEO

Per-GEO floors for interstitial traffic. The platform shows minimum bids and volume by GEO and platform for this format; the table is loaded from the traffic-volume page and re-read by the daily refresh job.

Who interstitial traffic is for — and its limits

Interstitials fit advertisers who want guaranteed viewability for a bonus, install or sale message. Two limits to weigh before you buy:

  • Intrusive by design. Publishers cap frequency per session and the skip timer is short; plan the message for a two-second read.
  • Creative work required. Unlike popunders, you need portrait and landscape artwork sized for full screens.
Where the numbers come from. Daily volume is the Reacheffect dashboard total for this format, all GEOs and devices, exported ; the traffic-volume table is generated from the same export, so the two always agree. Minimum bids are read from the Reacheffect platform on the date shown. Vertical fit reflects what advertisers buy this format for on the network. Nothing on this page is an estimate of a competitor's inventory.
