Intersitital > Description

The interstitial ad type is due to the coverage of large content areas highly attention-grabbing and very well suited for animated or interactive awareness campaigns.

The interstitial covers itself upon the start of an app, mobile page or page break over a majority of the content area on the screen and always includes a close button in the upper right corner.

The user can interact with the ad, reach the landing page or close the ad by tapping on the close button in order to return back on to the mobile page / app.

Close Button > Close button

The developer should not include a close button for the interstitial. The close button will be added by us. However, a free space of 50x50px must be left in the top right corner for the button.

GDPR complications

Because of the GDPR, some of our publishers only allow physical delivery or trusted hosting partners like us. We highly recommend the hosting in our infrastructure.

Only with additional signed GDPR agreement

  • Self hosted
  • External trackings
  • External resources (CDN) like JQUERY, Google Fonts, etc.

Self hosted ads

Be aware that some of our publishers still do not allow self hosted ads, external trackings or the use of external resources even with an additional GDPR agreement. In this special case only physical delivery or hosting from our side is allowed.

Physical delivery or hosted on our infrastructure

  • as a flat-ZIP file (without folder structure)
  • the ZIP file must contain (max. 10 files)

    • index.html
    • all resources (CSS, Javascript, images, videos, etc.)
    • all used Fonts, Frameworks, etc.
  • the total size of the ad should not exceed the total limit



Inside of your ad you have to read the clickTag from the query string IAB Guidelines (see Section 3.10.1).

Below you can see the function from the IAB for getting the clickTag from the querystring.

function getParameterByName(name) {
    var match = RegExp('[?&]' + name + '=([^&]*)').exec(;
    return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
var clickTag = getParameterByName('clickTag');

clickTag naming convention

clickTag should be always in camel case notation.

Special requirements for self hosted ads only

Ad delivery

Your developer should provide us an iframe tag like the following example inside of a text file (.txt) to avoid being blocked by our spamfilter.

<iframe src="" width="300" height="600" border="0"
        seamless="seamless" frameborder="0" scrolling="no"></iframe>


We recommend that your ads are completely responsive.
