Most people looking to run a legitimate home based business opportunity turn to the Traffic Exchanges to try and enhance free traffic to their homeworker opportunity website, or affiliate web page. In order to be more effective with traffic exchanges you need to maximise the credits you have, and minimise the amount of surfing you need to do to gain those credits. Almost all Traffic Exchanges will give you some form of free advertising credits if you can refer new members to the exchange. On that basis, if you're going to use a traffic exchange at all, you should use it in conjunction with a downline builder that supports it.
