how to track overture/msn with analytics

it appears you can track overture and other cpc programs with analytics, but i cant figure out how. can anyone shed any light on this for me?

 

I think you need to add some parameters to the end of your urls.

 

you mean for the cpc landing pages such as www.mysite.com/page.html?example1


will analytics pick this up automaticlly or do i have to do something within it?
