Creative
The Creative is the advertisement content itself (usually an HTML/JS file). For a creative to become "High Impact," it needs to communicate with the website it is being displayed on.
Advantage uses a Messaging Protocol to bridge the gap between the ad (inside an iframe) and the website. This allows the ad to safely request more space, handle scroll events, or trigger full-screen effects.
How Communication Works
The Advantage and the creative communicate by exchanging asynchronous signals. In the most simplistic overview:
[pre-AdVantage]an ad is matched and delivered to a webpages placement.- Once in a state to receive information, the creative informs AdVantage that it is ready to receive initialization information.
- AdVantage initializes and provides the creative with a
initmessage. - Creative executes, using messaging protocol to request and resive data and event about resize, close event, scroll event etc.
