DaveN is losing trust in AdWords. He recently started a thread at Search Engine Watch Forums named AdWords In UK Sucks -- Massive Duplicate Ads Get Through. He puts up a screen shot of a search done in the UK for plumbers ripon and if you look at the AdWords results on the right, all you see are ads from thomsonlocal.com. DaveN hosted a screen capture of this at Flickr.
Moderator, ChrisD explains that normally this is "a blatant breach of the Editorial guidelines." He quotes a help page at AdWords Support;
We do not typically permit advertisers to manage multiple accounts featuring the same business or keywords. When we find that an account is not in compliance with our double-serving policy, we will prevent multiple ads from appearing on the same query...........Advertisers seeking an exception to Google's double-serving policy must contact AdWords Support. We take the following into account when reviewing requests:
The destination site for each ad offers different products or services (for example, a large manufacturer with two product sites, one solely for stereos and one solely for computers, both running on keyword 'electronics'). Each destination site has a different layout and design, and each URL and domain is different.
Members in the thread are not happy about this. A Google technology loophole or a special exception to the policy for Thomson? Forum discussion at Search Engine Watch Forums.
