I attended SMX 2012 in NY and learned a lot, as I was just beginning to learn about SEO. Ten years later, I am now back in a position where we have an initiative to improve our SEO for three websites. In fact, just the week prior to my registration, I was telling my boss about this conference. First of all, they were free, so it was very easy to convince my boss to have two days to study this topic more in-depth. Secondly, it has been extremely helpful to go back and watch the videos again to catch things that I missed the first time around!
