Ad must have a strong background color or border.
Animation cannot be longer than 15 seconds including looping.
Audio must be user initiated.
Less is more. If you give the reader too much info, there’s no reason to click.
Always include a call to action.
Never, ever make an image larger. This blurs the image, logo, graphic.
Never change an advertiser’s logo in any way.
Stay away from gradients, drop shadows, stroked text, embossed text, etc. These raise the file size and reduce the readability of the ad.
Check the advertiser’s website for design style, colors, etc.
If providing tags for 3rd party tracking, 1x1 Impression Trackers and Click Tags are accepted.
