What’s the difference between a Destination URL and a Display URL?
The destination URL is the address of the web page that is displayed when an ad is clicked. The display URL, usually shorter than the destination URL, is the address that is shown in the ad. If the destination URL is long, include a display URL. For example, an ad with destination URL of http://www.electronics-planet.com/s_id=0&bc=1005 could have a display URL of www.electronics-planet.com – which is the URL that is shown in the ad.
