Bonzai Scrollex

Back to Ad Specifications

The Scrollex is a perfect mix of maximum engagement for advertisers and respect for the experience. Unlike a frustrating pop-up, which are intrusive in the experience, Scrollex uses the natural behavior of scrolling down the web page to consume the content. You can even make a Scrollex with any existing video/image assets you have. Typically, this format with a call-to-action in it performs best.


Format can only be 3rd party served by Bonzai (
