A full-width, high-impact banner placed above the site header — the first thing a visitor sees on the page, before any editorial content. Only one sponsor’s creative runs at a time, and it’s tied to the flight dates of a single GAM line item, making it a premium, share-of-voice placement rather than one that rotates with other advertisers. It’s most commonly sold against the homepage but can run on any high-traffic page. Creative is built at a wide, short banner ratio (roughly 6:1) and scales to fit the visitor’s screen rather than being cropped.
