Just found out about AdCenter’s new Video Tutorials that are very good -and explain how to set up campaigns and choose keywords.   I think this was a missing element of AdCenter last year - when people started using AdCenter - it was difficult to set up a campaign and the interface was buggy.  Now it’s gotten better.  

I still did not see them to a good video on Keyword Research or explain the Geo Demographic Cluster that are used in the Lifestyle charts - I’m sure they’ll eventually come forward with that information.  I like the improvements and the Tutorials.
