Depending on your site content, there may be a side of inbound search traffic you haven’t considered or quantified: image search. Honestly, I hadn’t thought much about it, but after reading this blog post over at SEO blog BlindFiveYearOld.com, I’m interested in making this data a part of my normal rounds of site analysis. There is significant configuration required to get this analysis, and it is documented nicely in this post. It requires creating another profile within your existing Google Analytics setup, and also requires configuring filters, a worthy, but slightly intimidating tactic I first encountered when setting up cross-domain tracking with GA. Check out the post and open a new venue for search data to come into your purview!

PS – check out this simple Regex Cheat Sheet to help you configure filters and more in GA. (Side question: will SiteCatalyst ever support Regular Expressons?)
