The key to success for an online business is good search engine ranking. Most major search engines count link popularity as one of the primary factors in ranking your website - so the more high quality, relevant links that lead to your site, the higher it will rank. Use relevant link exchanges. The most effective way to interest webmasters in linking to your site is by offering to exchange reciprocal links. Create your own link page with relevant websites.
Note: Unless the actual page your link is on has a Google Pagerank of 4 or higher, that link will not do you much good. It won't show up in Google. And it won't help your rankings much.
