To be a part of Raptive Rise, you agree to run our standard optimized layout. Unless the ads are impacting your site layout or design, no changes can be made to your ad layout.
That being said, you will receive access to the Ad Preferences page two weeks after the ads have been installed on your site. This will allow you to choose between high (25%), medium (20%), and low (15%) density options, control what ad categories show on your site, and more.
