 ## Overview
 Ads are just another external resource and must play within the same constraints placed on all resources in AMP. We aim to support a large subset of existing ads with little or no changes to how the integrations work. Our long term goal is to further improve the impact of ads on the user experience through changes across the entire vertical client side stack. Although technically feasible, do not use amp-iframe to render display ads. Using amp-iframe for display ads breaks ad clicks and prevents recording viewability information.
