That's the AdWords game in a nutshell! :)
We need to come at the challenge from several directions, and the way they interact can be a balancing act sometimes.
1) Create effective ads. 2) Get those ads in front of well-targeted eyes. 3) Create landing pages / sales funnel that make it easy, obvious and attractive for users to do what you want. 4) Tweak, test and improve. 5) Tweak, test and improve some more.
