I enjoyed Aaron Wall's and Larry Kim's just do it philosophy. Test some content, see how it ranks, move onward.

Larry Kim's thoughts on keyword effectiveness are global in nature. A team effort on hundreds of grouped keywords will yield more visitors than obsessing about page rank for one long tail keyword (a good thing to remember when your Chief Marketing Officer asks why you don't rank #1 for some keyword phrase).

Recently I learned the importance of [intitle:keyword], [inanchor:keyword]. Nice to know I actually knew something already from the article.

I liked Federico Munoa reminding us to do our homework on Yahoo and Bing regarding competition.

When I have a chance I look forward to testing all of the suggestions from your contributors.

Two additional comments.

1) Before you focus on SEO for a long tail keyword, shouldn't you test it with PPC first and a test landing page?

2) Is there any software for keeping track of keyword SEO campaigns that are global like the ones Larry Kim described? If we focus on a 100 keyword groups how do we track our progress over time with with those 100 groups, their SERP improvements, and their ROI to the firm?

Thanks Ken. Thanks WordStream. Great brain food.
