I first created this list of bookmarking websites back in 2008 and I have maintained it ever since! Unlike all the other lists on the web, I keep mine updated every month. I remove any sites that stop working, and constantly add fresh new ones.
There are a huge number of potential sites that can be included in the list but most of them are absolute trash and carry no authority in Google. Each month I hand pick sites that already have high page rank, and I test them manually to make sure they actually work!
All of the sites are completely free to use, and needless to say, this list of them will always be free as well.

The early social bookmarking sites were nothing more than a place to store your bookmarks online (rather than just on your browser) but it wasn't long before sites such as Digg expanded on the concept and they began to evolve into social sharing sites.
Every bookmark placed on one of these sites is a backlink to the content that is being bookmarked and in the case of dofollow sites, which all these are, they will pass some of the link juice from the bookmark site to your site.
As well as the link juice that comes from the bookmark links themselves, if you're lucky enough to get your bookmark onto the front page of one of the really popular sites, it can actually send a flood of traffic as well! Though don't get too excited, as this doesn't happen very often.
Even though it usually takes less than a minute to visit a site and submit a bookmark to it, with this many sites in the list it would probably take you an hour or more to submit your bookmark to all of them - and that's just for one piece of content!
The real power in social bookmarking for SEO comes from being able to submit bookmarks to a ton of sites in bulk, very quickly. They work very well at tier 2 and beyond to get your content indexed, boost up your tier 1 links and add greatly increase your domain and anchor text diversity.
Along with the list of sites, I'll also give you a ninja guide to bookmarking effectively. I'll show you how to drastically speed up your submissions using a couple of free online tools, and if you have a few dollars to spend, I'll also show you some professional tools that can submit your bookmarks to dozens of sites completely on auto-pilot with just a few clicks of a button.
Every submission of a piece of content to one of these social bookmarking sites creates a new backlink. If you are creating content on a regular basis, and you bookmark all of that content to multiple sites each time, and additionally go back and submit your existing content to new bookmark sites, you're going to be bringing in a steady stream of fresh backlinks to your website on an on-going basis.
You control every aspect of the bookmarking process and you can use these links as a great way to manipulate anchor text. By making use of spintax which is built into the bulk submission tools you'd be able to hugely diversify your anchor text which is extremely important these days post-Penguin.
There are some very high PR, high traffic bookmarking sites that are either nofollow or they use a dynamic link structure. So, they haven't been included in the list.
However, leaving aside the nofollow debate for a moment, there is also a matter of traffic. If the content you are bookmarking is high quality then it could get votes from other readers and in the case of some of the big sites, getting your bookmark on the front page can result in massive amounts of traffic! In the case of particularly big sites such as Delicious, those bookmarks often get copied to many other places so one nofollow link in delicious could actually result in about a dozen links elsewhere though this tends to happen only with popular links.
For this reason I’d recommend submitting to these sites also, and just forget about whether or not they follow!
