Yes you can, but the google QS is a tough one to get past unless you have some great unique content.
We had a site we tested that at first adwords wanted $10.00 per click just to activate our ad, and if we would of done that it would of automatically gone to the top and got clicked @ $10.00 per click.
But we then changed the content and KW density so then when the google QS bot came around again it adjusted our bid, and with this site our bid went to 4cents per click.
And heres a trick if you get stuck in the google QS game on adwords, everytime you change your content or site so that you will get a better QS create a new ad in that group and pause your other ad(s) , that way the google QS bot will have to allready come to check the QS revelency of your ad and thus gets your page QS redone and saves time, because sometimes the google QS bot will take 24hours, and if your trying to make $ that wont help
