I have been testing PPC for a while, but I think that I should try to learn new techniques and actually I'd like to learn a lot of the basic stuff as well. Can you recommend any e-books or courses (videos) that I should read in order to get the information I am looking for? Jens
There's a good if slightly dated book called Winning Results with Google Adwords. Written by Andrew Goodman. Definitely worth $20 or whatever and few hours...
