I have a section on a website where I show a list of posts from the past. The list is randomly generated and it's changing every time a page is loaded.
I was wondering, would it be better to add a rel="nofollow" to these links or not? I'm worried that Google might think it's a strategy to have more keywords on the site and that content displayed for search engines is different from the content I'm serving to "regular" users.. but then Matt Cutts says he wouldn't add rel="nofollow" to internal links. What do you guys think?
