Google has a policy that your display url must match your destination URL.
As most advertiser's know, having google.com show up in your ad, can drive a huge click-through rate. So what can you do to get google.com to show up in your display URL without breaking this rule?
Search Engine Watch Forums moderator, abbottsys, tested out a theory that actually worked for him. abbottsys created an ad for a search on ivf, the ad's destination URL goes to a search at Google for site:www.integramed.com/inmdweb/ ivf. So, as you can see, the ad's destination URL is google.com, but the search results are limited to a client's site. So, his ad was approved and looks like this:
abbottsys has noticed crazy improvements over his other ads. abbottsys said, "the new ad is blowing away my regular ad both in terms of CTR and conversions. Testing really does pay." Just as we thought. Great job and awesome test.
I wonder how much longer Google will allow such a test. If this sticks, maybe other advertisers will try it out. Very innovative and creative abbottsys.
