When you use this technique, you barter with other Web sites to trade ads with their sites. If you are browsing the Internet and find a site that you think appeals to your target market but is not a direct competitor, then ask for a trade. Send the Webmaster an email outlining your proposition. Include the reason you think it would be mutually beneficial, a description of your site, where you would place that site’s ad on your site, and where you think your ad might best go on their site.
When you make arrangements like this, be sure to monitor the results. If the other site has low traffic, then more visitors could be leaving your site through its ad than are being attracted. Also, check the other site regularly to make sure that your ads are still being displayed for the duration agreed upon.
