My 2012 goal is to nail down my system so that I can rinse, and repeat. I have had some successes with some sites but I've never really nailed down how I did it... So, I have been doing some homework and all the SEO folks who have a system that they have perfected say,"Figure out how to replicate what 'natural link building' looks like, then automate it." To me replicating natural link building would mean to get a bunch of diverse ( combo of web 2.0's, book marks, comments, directories, ect.), authoritative, and in subject backlinks? Of course this is assume that your on page SEO is perfect. For those of you who have your SEO system nailed down, is this it? Or am I missing a major key step?
