What are Mobile Web Interstitials?

In the simplest explanation, Web Interstitials are ads “in the spaces between”.

Web Interstitials are full-page mobile and desktop ads inserted between pageviews, designed to respect user experience while offering publishers high-performing opportunities.


What are the benefits?

  • Incremental Revenue: Access to inventory between pages that have previously not been available, unlocking incremental inventory and revenue.
  • High CPMs: High viewability creates strong demand with buyers across both desktop and mobile web.

  • Positive user experience: Fast loading, strict frequency capping, and a clear opt-out make interstitials compatible with the Better Ads Standards.

  • Easy Set up: All set up is done on Venatus side so you can just watch your revenue grow.

What about the user experience?

Venatus always cared about the user experience and this is the reason all our formats are certified and user-friendly. Web Interstitials are no different and we made sure that the user experience is respected through the following measures:

  • Fixed frequency cap of 1 ad per user per publisher per hour. Google sets frequency capping by default–1 interstitial ad displayed in an hour for 1 unique user. This capping limits the number of times an interstitial ad will appear to the same user. So, you don’t have to worry that the user will see the ad every time he switches the page.
  • Creatives are pre-fetched to minimize load time
  • Approved by CBA: Better Ads Standards
  • Clear close button to navigate away from the ad


We advice using interstitial ads for your mobile site because they enable high-value impression delivery and increase your ad revenue while respecting the user experience.
