Submitting articles to Digg is one of the best ways to draw traffic to your site without spending a dime. The only requirement is that you should have some high quality posts that are worth digging. You should also know how to entitle them in order to attract a lot of traffic. If you are already using Digg, you may want to start using one of these tools in order to enhance your productivity:
• Digg This for Firefox is a plug-in that allows you to select any text while browsing the net when using Firefox and submit it to Digg by right-clicking and selecting “Digg This!”. I think this is the fastest way to submit your post.
• Digg Alerter can track the Digg stories you have submitted along with their Digg count, so that you will be able to see if they have gone popular or not. Great tool for monitoring the status of your stories, especially useful if you are pretty active on Digg.
Submitting your articles to Digg will surely result in a lot of new visitors if you know what you are doing. Make sure to only submit articles that are really interesting.
