If you're lucky enough to happen across this post, you'll like this article dealing with the Increasing Complexity and Volume of SEO Tasks.
The writer Everett Sizemore, touches on virtually every aspect of SEO, new, old, what works and what doesn't anymore. It's a massive article of which I haven't finished reading yet but I'm thoroughly enjoying it.
It's also interesting how he seems to believe that SEO has evolved so much that they're not SEOs anymore, but are Internet marketers. I definitely concur.
I think I'm going to take a lot of his list and make my own file to refer to.
Either way enjoy and enjoy your weekend!
