I do not use adwords. Try to get all traffic generated through google searches alone. When you do the google search do you come up high on the first page of the search results?
Is the problem only with the ad words or with the google search results too? Seems to me that the ad words would need to have a good base to work off of with the keywords and general SEO strenght of the site. OK I did a google search for Denver process servers and you came up second on the list of the first pg so that seems to be quite well. Guess I do not know anything about this and will bow out and stop wasting your time
