Do Follow Social Book Marking Sites
Social Bookmarking is a nice way to get some “additional” Google juice (and traffic), particularly when you have a lot of backlinks and need that little bit of extra numbers.
Here are 60 social bookmarking sites that have dofollow links and do pass some Google juice one way or the other to the listed sites. Let me warn you that these are not effective if your link building campaigns ends with only these, but they are nevertheless worth a try.
Mind you, although these “might” work with extremely low competing keywords, they don’t stand a chance to substitute a proper healthy link building strategy/campaign.
Have fun trying them out. I don’t guarantee that all of them work, but some of them are really good while some give only temporary links. I suggest you take some time out and try out each one, trust me you’ll find some gems in there.
