Hello. I've just sign up for a google adwords account. Where can I find full info / tips / case studis on how to manage this account ? (what are the best keywords, how should i set the budget and so on) Thanks a lot.
You may want to either buy and ebook on adwords by searching the net or try google's help files when you login.
PPC Discussions is a huge resource for AdWords and account management also (Its on my daily read list)
