  • If the Expanded Panel is roll over to expand, the user must mouse over the creative for more than 1 sec.
  • Default unit should clearly state that the expanding panel will expand or extend upon a given user action (click to expand or rollover to expand).
Design and Performancea. Content: To protect our brand please ensure:
  • All images and content are appropriate to the general audience nature of the homepage.
  • The ad does not try to launch parts of the ad in a new browser window (pop up/pop under) or shake the browser window.
b. Performance: Please try to minimise the CPU load of any Ad Units submitted and bear in mind that there will be other flash elements on the page slowing down the users machine. Any ads that cause excessive CPU load and damages user experience once tested on the page will not be accepted.

Note: All ad executions are subject to approval and Nine Digital reserves the right to request changes to content and/or execution for brand equity/user experience reasons. If you are unsure about a concept that you are working on please submit it to your sales rep for feedback.
Timelines and Deliverya. All 3rd party creative should be delivered to Nine Digital via 3rd party ad serving tags.
b. All materials must be delivered at least five (5) working days prior to campaign launch to ensure technical compatibility and internal concept approval.

Note: If creative is late an estimated % of impressions equivalent to the prorated daily inventory level will be cancelled from the total impressions booked.
