A thread at Cre8asite forums named Google Violating Ad Editorial Guideline, Nothing really informative here shows a possible case of Google violating its own Google AdWords Editorial Guidelines.
From the guidelines;
Display URL Must be Accurate
- Your Display URL must accurately reflect the URL of your website. If your actual destination URL link is too long for your ad, use a shortened version (such as your homepage) that meets the character limit for this field.
- The Display URL field cannot be used as another line of ad text.
- Your Display URL must include the domain extension, for example: .com, .net, or .org.
Destination URL: http://www.shoesforsale.com/ladiesshoes/highheels.html
Display URL: www.shoesforsale.com
Now, the thread notes that a member saw an ad, by Google that read;
Learn how you can earn money by blogging. Put AdSense on your blog!
When you clicked on the ad, it took you to a google.com address and not a blogger.com address. Even though Google owns Blogger, putting the URL Blogger.com in the display URL and sending someone to Google.com may be against the Google AdWords Editorial Guidelines.
