Ari Ozick, a friend of WordStream and a great contributor to the SEO Book forums, is launching a new SEO guide soon: The Contrarian Guide to E-Commerce SEO. We got a sneak peak at the guide and it's got a ton of advanced information for "e-commerce site owners and marketing managers who want the nitty gritty on SEO, and have the resources to drive their SEO efforts."

You can sign up now on Ari's site to get on the waiting list for the guide. We'll do a more in-depth review when it becomes publicly available.
