Design Requirements All units must have a 1 pixel solid black border, and an opaque background color. If the creative has a black background, some publishers require the 1 pixel border to be white.

Remove any margin/padding from your document, so that the creative sits flush to the edge of the page, and be sure that the border does not exceed the unit's dimensions. Expanding banners should be aligned opposite to its direction of expansion. For example, if a single file expanding big box is designed to expand to the left, then the creative should be aligned on the right side of the page.

Double check the above with media planner as individual sites can have different size and timing restrictions. Also reference the list of site specific requirements.

External Resources

All assets must be hosted on eyereturn's servers.

eyereturn certification by the major publishers and networks is based on eyereturn hosting all resources loaded and used by an ad unit. Rare cases where assets or resources must be hosted on a non-eyereturn server must be discussed and approved by eyereturn and the publishers before serving. Any externally hosted resources must also be disclosed to the agency. eyereturn cannot be responsible for the speed, quality or content of externally hosted resources.

Event Tracking

Any function or user interaction within an ad unit may be tracked. Please use eyeBuild (click here for more information) to add appropriate tracking OR send us a document detailing the unit's tracking requirements.*

Identifying the correct functions to modify with tracking events can be difficult and time-consuming in complex and unfamiliar applications. Wherever possible, consolidate your tracking methods by creating an easily located section of blank functions called by your trackable events in which eyeReturn will place our tracking events, or commenting your code to indicate where tracking events should be placed.

*In some cases, additional charges may apply to non-standard tracking requests
