Google launched a new “beta advertiser feature” that enables brand advertisers to target their ads to ad units that’re immediately visible when a page is loaded -- in other words, the portions of the page a user can see without needing to scroll down. “The ads that’re immediately visible are called 'above the fold'; those that require a user to scroll down in order to be seen are called 'below the fold.' In order to determine which ads are above and below the fold, we've implemented a statistically-driven model. The model takes into account various user experiences and situations, including different web browsers, monitor sizes, and screen resolutions, and only considers ads above the fold if they’re fully on-screen when the browser window loads. If you've placed your ad units above fold, advertisers using this feature will now be able to reach your site in a new way. If you haven't, placing new ad units above the fold will enable them to do so,” explained Google.
