How does SEOMoz crawl sites? Does it follow the sitemap?

I only ask because in my report it returned a few "no follow" links. Was wondering how SEOMoz operates.

My guess is they spider the way Googlebot spiders - finding links on your home page, following those links, and finding more links on the subsequent pages, so on and so forth. I doubt they look at the sitemap, since it rarely reflects the true importance of pages on your site, which tend to be linked to more often.

Rogerbot, our crawler, obeys the robots.txt nofollow rules associated with your site. For some reason your robots.txt file is blocking our crawler from seeing those pages. For more information on how the tool works, you can view this incredible resource: http://www.seomoz.org/help/rogerbot-crawler that explains how our crawler works in vivid detail. I hope this helps!!
