  Third-Party Script Tags

When delivering the ad as a third-party script tag instead of image files, the ad needs to be responsive / scalable and adjust to both portrait and landscape sizes. If your script is not responsive we will only use the portrait size (320x480px). Must support HTTPS.

If delivering html5 assets to be hosted by Widespace, please see HTML 5 section.


Widespace always tracks clicks and impressions. Third-party tracking can also be implemented:

  • 1 impression tracker
  • 1 click tracker

Must support HTTPS.
