Mobile Rich Media Notes

Format: Third party JavaScript tags; HTML5; Animated GIF animation only. No flash creatives or iframes.

Animation: 15 sec max

Audio: User initiated tap only; 30 sec max - audio only and when in conjunction with in-banner video. Audio must stop when the banner is tapped or when the appropriate audio control buttons are tapped

Notes and Best Practices: Ensure all images are optimized for mobile web; do not use Flash creatives even if the tag contains a static backup image; use mobile optimized landing pages, include size dimensions in file name. For full screen dimensions, see Full Page Flex units for both tablet and smartphone.

High Resolution: For higher resolution devices higher file weights may be accepted but no more than twice the guideline
