How to work with .zip archive (template)

  1. Unpack an archive with the creative template.
  2. For creative preview use the preview page or copy all files to folder index – banners – banner- body and open file index.html in browser using localhost. In the later case a web server has to be installed (e.g. IIS for Windows, Apache for Mac OS).

    3. Additionally, you can check the preview of the creative by copying the link to it and viewing it from your mobile device.

  3. Open file body.html with the text editor and edit the code snippet inside tags <body> </body>.
  1. Edit JS files.
  2. Save and archive all banner assets in .zip (you should archive the files, not the folder that contains the files).

A simplified example of the globalHTML5Api.init usage for the Scratch format:

Expand the globalHTML5Api.init example code
globalHTML5Api.on("load", function (Scratch, Player) {

Event tracking

Any event available for an HTML5 banner can be tracked.

Chrome will limit the resources a display ad can use before the user interacts with the ad by removing heavy creatives from the page. An ad is considered heavy if the user has not interacted with it (for example, has not tapped or clicked it) and it meets any of the following criteria:
– Uses the main thread for more than 60 seconds in total
– Uses the main thread for more than 15 seconds in any 30-second window
– Uses more than 4 megabytes of network bandwidth
For any questions regarding ad manuals please contact the support manager of your account.
