If no targeted ads are available for your page, Google will show a transparent space instead of ads. However, you can set up backup ads to display an image or HTML page if Google isn't able to show targeted ads. This way, you can make sure that your advertising space is always being used effectively.
While creating or editing an ad type and backup ads style, you can specify any of the following as a backup ad:
- Image: You can use any static image as your backup ad. Next to "Backup ads," click Show ads from another URL and enter the URL of the image in the text box, including http:// and ending with the image file name. The entire URL must be 256 characters or fewer. For example: http://www.google.com/logos/Logo_60wht.gif
When you're creating the image, make sure that the dimensions are the same as the ad format that will display it. If your image is bigger than the ad format, the image will be cropped at the right and bottom edges. So, if you're creating a backup image for a 240x120 ad format, make sure that your image is also 240 pixels by 120 pixels.
- HTML page: This is useful if you'd like to implement a clickable image as your backup ad. The HTML page will contain the information required to load your image and link it to any destination.

Here is a sample HTML page with absolute URLs, as well as the

Once you've created and saved your HTML page, you'll need to upload it to your server. This page can be hosted anywhere online, as long as it's accessible from the internet.
Next to "Backup ads," click Show ads from another URL and enter the fully defined path to the saved HTML page. For example:
