Hey, I would like to extend and develop my knowledge of Google PPC and Affiliate Advertising.
It is very basic at the moment - actually it's very basic but I'm a quick learner and I have been in Internet Marketing for about 3 years so I know the concept of them at least.
Can anybody recommend any good books that I could purchase on these or where on the web is best to read up on these in depth from a basic to advanced level?
Much appreciated.
