Pushdown or fixed leaderboard advertisements, static or animated, are displayed at 960px (width) x 160px (height) and can be upgraded to include float. Also available at ‘billboard’ size, 960px (width) x 320px (height), which can contain embedded content for user interactivity. Leaderboard ads are prime online positions – located above the main content of the page – which draw the eye as the page is displayed. Their close proximity to the content of the page makes them consistently noticeable and impossible to ‘avoid’ – readers’ eyes are drawn to them naturally as they interact with the page, reducing the impression that they are being overtly encouraged to click on an advert.
