Features
The Tower ad format is a vertically floating inline banner typically positioned in the side column. When the user scrolls, it follows and remains in the viewport within the available (predefined) space.
You need to specify the height of the column and leave space for the ad. If none is specified, the ad format will behave like a Default Banner. You can also define the height on insertion level - it is available as a creative template parameter.
This ad format is designed for web only (no mobile web supported).
Click management for HTML5 creatives
The Tower ad format is able to identify the click destination for HTML5 creatives by using:
- the click counting library
- the clicktag variables passed in the source of the iframe; Important: HTML5 creatives must have the click destination recognition implemented:
