There is basically two ways to drive traffic to a web site
- Banner ads
- Pay Per Click
- Pay Per Conversion
- Search Engine Optimization (or Search Engine Marketing)
Each of those topics is not just explained in a few sentences. Some here gave you already very bad scores in terms of Search Engine Optimization of your website.
I`d also urge you to not look at this only through the online lens. Make a complete Marketing plan with things like e-mail, website, advertising, customer relation ship management and customer retention in mind.
As a general rule of thump you do not want traffic alone, you want the right people coming to your website/online store and you want them to buy. So think of promotions, seasonal to the right audience, etc. Again you need to make a marketing plan rather than "drive traffic"
