Some free methods of bringing in traffic to your site are Twitter, Facebook, YouTube or any of the other video websites, UsFreeAds, CraigsList, web forums that are related to your products, free blogging platforms like Blogger or WordPress, safelists (dependent on the product or service you offer), keyword-targeted PR releases, traffic exchanges, article promotion to EzineArticles and other article directories, and more. If you have some money to spend, you can invest in PPC (PPC) advertising on any of the leading search engines (Google, Yahoo, and MSN-Bing). The best thing about this kind of advertising is that you only spend what you need to spend. You bid on certain keywords or keyword phrases and then you get charged only when someone clicks on your ad. If you do not have lots of money to spend, ensure you select the lower-searched keywords so that you can bid lower.
Another paid options is Ezine advertising. Ezines are online magazines. The best kinds of ezine advertisements are called “solo adverts” which suggests that your ad goes out alone (with no other advertisements) and with your own e-mail subject line, not a generic subject like “Newsletter number 20″ as an example.
