One of the best social networking sites around in terms of boosting the number of readers your articles can achieve. However, these reads aren't necessarily from people who are interested in reading your content. How StumbleUpon works is that you sign up and select a certain number of categories that you are interested in. Once you click the "Stumble" button, you are then sent bounced to random webpages that are to do with one of your specific interests. If you have your blog content within StumbleUpon, it means that your article will be one of these pages that users see.
When you use Stumbleupon, you need to make sure that you don't use it as a one way street to only promote your own content. If you continually submit pages from the same URL address, StumbleUpon will tag you as being a spammer and will block you from submitting future pages from that URL. To avoid this you need to make sure you use the bookmarking site to its full potential. Visit different websites that are of interest to you and like their pages. This will not only tailor your Stumble feed to show articles that are of interest to you, but will also allow you to keep posting your own blog articles without being seen as a spammer.
Digg is a social bookmarking site that has stood the rest of time, still ranking in the top five of all bookmarking sites despite being one of the first created. While it is harder to get reads on Digg as opposed to the previously mentioned StumbleUpon, if you manage to get your blog posts on to the front page of Digg you are guaranteed to have people reading your article in droves. Posts that tend to do better than others on Digg are news articles and niche articles. What I mean by niche is articles that stand out from all others, creating humour and touching on a topic that previously hasn't been touched on much by other users.
The first ever social bookmarking site to go live on the Internet and it's still going strong today. Delicious allows you to simply add links to your blog article and then add as many tags to that post as you like. The more tags you place on a post, the more chance that users are going to come across it in their search. LIke Digg, your blog post will only really receive significant amounts of traffic to your blog if it manages to make the front page. There isn't really anyway to artificially enhance this, you simply need to wait for people to like it and move it up the ranking.
Unlike the previous two social bookmarking sites, Digg is a site that you need to work hard at in order to make your posts a success. You cannot simply add your post to the site and then be done with it until you next wish to add a page. In order to achieve the best levels of success, you need to regularly engage in conversation with other users and help them by providing content and other information that could be of use to them.
A bookmarking site aimed at people interested in Internet marketing posts. However, the site does allow you to post articles that are to do with related topics such as ecommerce, advertising and other forms of marketing. The website is very much in it's infancy but is full of potential. If you are someone who regularly creates posts on these subjects, it will allow you to create gain a number of dedicated number of followers who will become interested in any future posts you make.

While these sites aren't considered social bookmarking sites, it would be crazy not to use them to promote your blog posts and articles. Twitter, Google+ and Facebook are still some of the best ways to promote your blog, articles or anything to do with your business through social interaction and social commerce. With over a billion combined users, the potential audience you can reach is simply staggering, meaning that one single post could be shared between your friends and other people who are interested in your site, allowing you to gain a substantial number of reads in a short space of time. Not only that, it allows you to promote your online store and brand image easily, enticing users to visit your site.
