I have been wondering that are there still social bookmarking sites similar to digg that pass link juice. I have checked out many of them, but all seem to have rel=nofollow. Are there still some dofollow sites available?
There are many lists of do follow social bookmarking sites on this forum as well as by doing a search engine search for do follow social bookmarking. A word of caution: I check on them from time to time and the number that were do follow 6 months ago has dwindled and apparently will continue to dwindle. There is benefit from no follow- although no link juice passes as some search engines ignore the no follow attribute. Best idea is to use the firefox tool or check manually yourself as what was do follow in sept may not be do follow today.
I recently been wondering the same question, but haven't found much, most are no follow, i suggest using a social book marking service, which i have been using, save me alot time and you can find some good prices on some good packages.
