Making friends and networking with
other SEO pros and consultants, the questions
and answers (Q&A) forum with SEOmoz staff, the tools, content and exclusive pro member discounts (conferences, link buying, call tracking, SEO
analytics from Enquisite etc.), are more than worth it!
For an example of the great friends SEOmoz Pro helps you make, here I am with Tom Critchlow of Distilled, at the SEOmoz Pro-members-only party
at SMX Advanced.
