I feel like I've seen a lot about Tumblr lately, and I recently started my own diversity book tumblr (separate from my personal) and I'm wondering if anyone has any specific tips about marketing. I think it's very difficult to market a Tumblr because of it's nature, w. following and how it's easy to miss things on your dash. I've pitched my blog to some places (as well as mentioned it here) and started using Google Analytics but I'm wondering if any marketing gurus have concrete advice? i.e. Does SEO work for Tumblr? Thanks!
