Google has given their advertisers the ability to safely view their ads, without it costing them anything. A feature request that has been on advertisers most desired for a long time. How does it work?
The Inside AdWords Blog says you can test your ads at www.google.com/adpreview. Give it a try, if you attempt to click on an ad you will get a prompt stating "Links are not available on this test page."
|Warning: This page is a tool for AdWords advertisers to test their ads. For full Google functionality return to the Google homepage.|
What about testing if your ads are shown in different locations, countries or US states? The blog says that this URL will do the trick for displaying ads for camping tents in Chicago, IL.
There is slight confusion about that location based test, because of the URL parameter.
