Is the best resource to learn ADWORDS - Just to go through the Adwords Tutorials on Google's Adwords Site? I know there are Ebooks - But they are generally out of date and tell u what you already know.
This will really help you. I've had a lot of success with this. You can find the link at microsaw.com under the 'adwords' button. The 5-day course is complimentary, and it's a great way to start. Specially if you are frustrated with trying to beat the adwords system. Written by one of the best in the industry. Let me know what you think.
there is this free ebook found on this thread at DP. Good for beginners. http://forums.digitalpoint.com/showthread.php?t=103764 I learnt all my stuff from the Google Adwords Help and mostly experience (trial Error, & testing).
I suggest Perry marshal. he's the king of adwords. does it himself & for clients so he's totally up-to-date. check the link that jrognerud gave you.. you can get his 5-day free course. another killer resource is this free ebook on adwords by brad callen. seems strange to say but.. you can get about half of perry marshal's $47 ebook stuff in this free ebook.. i uploaded it for my people here: http://www.secretsofthemilliondollarman.com/AdwordsmadeEasy.pdf enjoy!
I'm agree Perry Marshall "The Definitive Guide to Google AdWords" http://www.perrymarshall.com/adwords/index.htm
