If your station is currently implementing COVE Pro or COVE Plus, be careful when designing your header image to keep your logo and branding within the designated "safe space" of 650px X 92px starting from the left. The "safe space" shouldn't be confused with the full banner width of 950px.
Within the next few weeks, we will be launching a new ad serving solution on COVE that will insert banner ads into the header on the right side of the screen. If you've customized that area of the banner (indicated in the screenshot below), the new ad will cover anything you've designed.
We have already enabled the banner ad in the QA environment, so if you're currently in COVE, you can preview how your header will look with the banner ad in the QA instance of your portal:
The current development schedule has the new ad solution slotted to go live on November 17th. That means the ads will begin surfacing in any live instances of station portals at that time.
