Dig deep into everything you ever needed to know about links from anchor text to redirection. Read this series of pages to understand how and when to use nofollow and whether guest blogging is actually dead.

I second Rand's comment! Congrats on moving from the corporate world to the independent consultant. This is my goal for the near future. I too have been testing the waters of independent consulting, but it doesn't quite pay the bills yet! Sometimes I feel like I should find a mentor who has been where I am now and is where I want to go. Perhaps i'll find a few in this community over time!
Social media is one of the most popular free marketing tools around, and plays a role in driving traffic to your website. Use Facebook, Instagram, and LinkedIn to promote blog posts and other useful pages on your website. This way you can turn your social media audience into website visitors, and draw traffic from their networks if you post shareable content.
Nice work Laura! This is going to be a great series. I'm working my way through SEOmoz's Advanced SEO Training Series (videos) Vol. 1 & 2 to build upon the advice and guidance that you and your team provided to me during my time at Yahoo!. Now many others will benefit from your knowledge, experience and passion for SEO strategy and tactics. Best wishes for great success in your new role.
