How do I set up a Google Adwords campaign?
You can view really useful presentations about Google Adwords and Google Analytics. There is a Google University beginners’ session http://services.google.com/awacademy/breeze/Beginners/index.html and an advanced session http://services.google.com/awacademy/breeze/Advanced/index.html.
If you don’t want to listen to the presentations, Google has a Learning Center where you can read through training documents http://www.google.com/adwords/learningcenter/
