One of the most fundamental ways to generate traffic is to have other web sites link to you. Finding those sites that are willing to link to you can be difficult though.
One way is to write articles and have them published. EzineArticles.com is an article marketing and distribution, publicity generating, and traffic building service designed to get your articles in front of a potential audience. There is no charge to use the service and all new accounts get to submit ten articles that will be evaluated for quality and reader interest. If you get accepted, you can constantly submit articles into their content directory. The high-visibility of the site, its value as a link opportunity, and the ability to distribute your content, with your site's link included, to a large audience of publishers all add up to a high-value traffic-driving opportunity.
