Head to any of the major social bookmarking sites, such as Digg, and you will find that there are thousands of people there posting links to different articles and blog posts throughout the web. Did you know that many of these are people who provide search engine optimization services and who are posting links specifically to gain attention for their clients?

Although Digg is the largest of the social bookmarking sites, it is not the one that tends to be favored by the SEO company representatives. That’s because Digg is a hard site to rank high on even if you have a thorough understanding of web marketing. Instead, these companies tend to focus on the other major sites that are also popular but which aren’t as complicated as Digg.

Three of the big social bookmarking sites that are used by these types of companies are StumbleUpon, Reddit and Delicious. These are the three sites that you would want to focus on if you were going to try to do your own social promotion. Sure you’d be competing with the pros but you would also be where everyone else is going to get traffic from social sites and that’s the whole point of doing this type of web promotion.
