There is a lot of discussion lately of using social bookmarking sites for links AND traffic. Generally, I think it is great for traffic however if you are looking for social bookmarking sites to pass PR/Trust Rank/Ranking Juice - many of the sites use redirects or the no follow tag.
I decided to create a list that has the bookmarking site, PR, has direct links, uses the no-follow tag. So if your time is limited you can, focus on the sites that make sense for your marketing efforts.
Note: the nofollow tag is not all that bad. The search engines will still follow the link for indexing purposes but don't expect much for ranking in terms of anchor text or passing PR.
I'll update this every month or so. Please let us know if something is incorrect or needs to be updated.
Feel free to use this list for your site or newsletter - all we ask is that you keep the link back to our site
- thanks!
