Out of all the social bookmarking services the one we rely on is Bookmarking Beast http://www.bookmarkingbeast.com . This is because they leave no stone unturned. They submit to the top social bookmarking websites and also the ones you probably never heard of. The end result is a fully automated system where they submit, and give you a full report each month in Microsoft Excel format. You get quality backlinks, and thousands of them for only pennies each. We’ve seen in increase in our search engine traffic and also referral traffic from others sharing our submissions. I highly recommend them.
