When I worked with a company a year or so ago I became Adwords certified. Now I haven't stayed up on my Adwords knowledge and if I claimed to be able to be Adwords certified I would definitely have to re-prove it again but this application is really good!
As it stands if you hear of this service and are seeking Google advertising professionals you can use this tool to find a firm in your area.
I know a lot of people are going to say "there goes Google, giving the market share to the rich, the ones who can afford to get Adwords certified" but everything starts off a little expensive and from what I remember it didn't cost over $400.00 a year ago so.
I think it's great and I think I'm going to go for a re-test or touch up cause I definitely want to be found on that list.
