SummaryStarting in Chrome M143, Heavy Ad Intervention reports will be sent to the ad's embedding frame, in addition to the ad frame itself. The report sent to the embedding frame will contain the ad iframe's ID and its pre-redirect URL within the report's
body's
message field. This change gives the embedding context -- which is often the publisher page -- the ability to identify and address disruptive ads to improve user experience. For more details on the Heavy Ad Intervention feature, see the
original blog post.
