    People who want to learn regex should also check out http://www.lunametrics.com/blog/resources/#RegEx-ebook by @RobbinSteif from @lunametrics. I can’t even count how many times I’ve gone through the ebook. It is an excellent resource.

    There is also a terrific series of posts on the Lunametrics blog.

    A very similar article with similar content was posted on SEOmoz a week ago. http://www.seomoz.org/blog/an-seos-guide-to-regex

    What’s up with this?

    Lindsey, thanks for your comment. I enjoyed the SEOmoz article, and I link to it in the fifth paragraph. The focus of this article is the keyword groupings I believe are most meaningful for understanding organic traffic with specific examples that I have used with clients. I definitely wasn’t trying to write a regex guide, though it’s hard to get into semi-complicated expressions with going into syntax at least a little bit.

    Thanks for your comment and the links, Yehoshua! The posts on greediness and regex in particular are very useful. Usually when I have a problem with a regex it turns out to be an issue with wildcards and greediness.

    Great article.
    Just to remind folks that RegEx expressions can also be used in the Site Search area of GA – very useful!
