Link exchange is a marketing technique in which two or more websites offering similar services exchange text or banner links.
Wikipedia.org say's this in its definition of a Link Exchange "Link exchanges have advantages and disadvantages from the point of view of those using the World Wide Web for marketing. On the one hand, they have the advantages of bringing in a highly targeted readership (for link exchanges where all members of the exchange have similar web sites), of increasing the "link popularity" of a site with Web search engines, and of being relatively stable methods of hyperlinking. On the other hand, they have the disadvantages of potentially distracting visitors away to other sites before they have fully explored the site that the original link was on.

Most search engines rank websites in terms of link popularity. The more inbound links there are to your site, the better your chances of appearing on the search page. A simple way to achieve this is to post links on blogs, forums, and other free sites, but that takes a lot of time and effort. With link exchange, you can get dozens to thousands of inbound links without having to set up each one.
Each inbound link acts as a door to your site. Post your link in an online forum or within an article, and people are bound to follow it. The more visitors you have, the better your chances of selling your product or service. And it's not just the number of site hits: because your links appear in relevant pages, you can be sure your visitors are interested in your business in the first place.
Free vs paid
Link exchange is usually free when you negotiate directly with other site owners. But when you use a link exchange program, there is usually a monthly or one-time fee depending on the contract. Companies such as GetSEObot.com offer basic link exchange for free, but provide additional benefits to paying customers. These include more SEO strategies, search engine placement, and ranking reports.
