Up to two small, or one large and one small enhanced sponsorship unit may be included on a program site page in addition to any standard messaging (assuming the 20% limit holds). The following Internet Advertising Bureau (IAB)-compliant units are acceptable:
- Small: 88x31, 120x90, 120x60
- Large: 180x150, 728x90, 160x600, 120x600, 300x250
Examples of these sizes can be seen on the IAB web site here: http://www.iab.net/standards/adunits.asp
Any other unit sizes must be approved in advance by Open Learning Labs.
All units must appear in the perimeter of the program site page design (top, right column, left column, bottom)
No more than half of the total enhanced sponsorship space can appear “above the fold,” as it applies to the total pixels allocated per the required resolution defined in the Open Learning Labs Web Manual for program sites.
User research shows that animation in banner creative should be used sparingly, if at all, within the program sites. The inclusion of animation should be considered carefully by the producer in regard to the user experience and overall tone of the program site. If images and banners are animated, they must adhere to the following specifications:
- For GIF or JPEG Images: up to 3 loops; maximum animation length: 15 seconds
- For Flash: primary Flash file animation is limited to first 15 seconds; continuous looping animation not accepted
