Hi John,
Welcome to Moz! Thomas definitely has you on the right track, but I've got a few recommendations of my own.
If you'd like to brush up on SEO and inbound marketing in general, I absolutely recommend reading through the Beginner's Guide to SEO, if you haven't before. It offers one of the best introductions available to the basics of SEO, and can be pretty easily read through in an afternoon. Cyrus Shepard's "How to Rank" is another great learning resource, and presents a more practical explanation of the SEO process. Then, of course, there's Moz Academy, which Thomas already covered.
It sounds as if you may have already seen it, but the Getting Started section of the Help Hub provides an overview of each of the tools we have available, including quick video introductions and documentation. I suggest looking it over once, then checking back whenever you feel confused about a tool or feature.
Finally, here's the basic process I tend to recommend to folks who are just getting started:
-
Set up the Brand & Mentions section of your account to get it started collecting data.
-
Add your competitors to the Links section of your account, in order to get their link metrics tracking, as well.
-
Use the On-Page Optimization section of your campaign, and particularly the page grade recommendations to get the on-page elements of your site under control. I recommend checking out Rand's post on the "perfectly optimized page" for pointers.
-
Use Crawl Diagnostics to work out anything that's causing issues for web crawlers.
Where you go from there will depend on your own goals and strategy.
Does that help at all?
