A Search Engine Watch Forum Thread named AdWords No Longer Human Reviewed? captures all of the blog coverage on the recent downturn of relevancy checking at Google AdWords. Blog coverage includes; ThreadWatch, SEW Blog, SearchViews and I know I have seen others in the past 24 hours. Basically, the issue brought up yesterday was when doing a search on even google, you get ads for "Make Money From Home", "Make Money Online", "Get Rich" and "Want Cool? - Get n8".
In the SEW thread, Mikkel deMib Svendsen says that "It's all about money!" for Google.
But just a few minutes ago Danny posted a follow up to the story named Humans Still Part Of Google Ad Review Process with an official response from Google.
Google uses a combination of humans and technology to review keywords and ads for relevancy, editorial guidelines and our content policy.
