Google Remarketing Banner Ad Specifications

Google remarketing is one of the most effective ways to target Internet users who have already browsed your website but did not purchase anything or convert. Different advertisements are displayed on different websites across a range of platforms, and are targetted at those that have already shown an interest in your product or service. Once set up, remarketing is automated and works effectively to increase your website’s conversions.

AdWords currently supports only Adobe Flash Player versions 4 through 10.1. If your ad uses any other version (such as 10.2), it cannot be uploaded.

You should see an option to preview a non-Flash version of your ad when you upload a Flash file. Don’t see this option? Make sure your SWF file uses ActionScript 2.0 and avoid filters or blending if possible.

Flash ads must support the clickTAG variable and the only user interactions that are allowed to be tracked are clicks.
