Exchange links to improve your search engine ranking
Exchanging links with other relevant / related websites can add to your ranking with search engines like google and Bing. Sites that link to you that have a higher pagerank are, of course, worth more to your site in terms of ranking than those with a low or zero rank.
If you are looking for a way to find sites looking to exchange links try Link Market. This is free for the basic service.
Do not be tempted to buy links. Search engines can ban your site for this practice.
