I was wondering if anyone has came across or recommends a good Google Adwords tutorial that teach me to write better Campaigns, Ads and Keywords? If you have used it, how did it help with your traffic?
It's hard enough to find a good system. I started with AdWords help to learn the basics, but I feel that it leads me towards increasing my bets too much. Adwords Learning center is a great resource. I'm trying to find my balance between the official sources, commercial blogs and "trial and error" method. You may also find this resource useful.
