"If you build it, they will come" is not necessarily true on the Web. Putting a website up is one thing, but getting visitors to come to your site is another. The process becomes even more difficult if you have limited resources to market your business.
You can try pay per click programs such as Google Adwords http://www.google.com/adwords or Yahoo Search Marketing http://searchmarketing.yahoo.com – though the key is to carefully track your ROI and which keywords actually perform well
Here are some shoestring marketing ideas that can help you get the visitors you need at the least cost possible:
1. Create the best content you can with the best products you can possibly offer. Your content is your best advertisement - if visitors love your content, then they will go back and spread the word to others.
2. Make it easy for users to recommend your site. Viral marketing is very important -- and easy to tap on the Web. But give your users the tools. Get a Recommend this Site script from websites such as cgiscripts.com and similar directories of scripts. Some even go as far as giving incentives to those who recommend the site to their friends. If only 10 people go to your site, but these 10 people invite 10 more - that's additional traffic that you get for FREE!

3. Rank well in the search engines (organic search results, not the pay per click). SEs can be a big source of traffic. The key is to create the best content in your niche. If you have good content, other websites will gladly link to you and offer your site as a resource to their audience. Check the on-page factors and be sure to get linked from authority sites in your topic area.

4. Send out press releases. While outfits charge as much as $650 per release, there are free press release submission places on the Web. Press releases allow you to (a) attract media attention; (b) get more back links to your website without sending each website an email request; and (c) get more visibility especially if your press release gets in Google News or Yahoo News.

5. Submit articles. Write articles and submit them to websites accepting author submissions. You get exposure for your business; establishes you as an authority in your field, and allows you to get backlinks for your website. If 50 websites publish your article and it contains a link back to your website, then you easily get 50 links from a single article. The more links you have, the greater your chances for increasing your search engine rankings.
