I'm sick of trying to please the stupid people of adwords. Until last month I had 3 campaigns running with very good results for some landing pages, until they came up with low quality score. WTF? they said that they had quality 8 and 9, I also have a site that is in position # 1 for my main keyword, with a lot of traffic and according with them, the site even scored well!. They can go to hell! I'm earning more money without their campaigns, using that site and now all is 100% profit.
