Joint venture marketing is probably the most underused free marketing method available to Internet entrepreneurs. Why? More than likely because of the stigma attached to partnering up in business. People are afraid of business deals going bad, so they tend to steer clear of any sort of joint venture. But unlike most joint ventures, joint venture marketing doesn't require sharing of profits. You merely share marketing tools. Let me explain what makes joint venture marketing such a great method of free marketing. The first and probably most important reason is that it provides endorsements from other merchants and with endorsements comes trust. Not only are you expanding your customer base to include your venture partner's customers but you will also be afforded more trust from your venture partner's customers because he/she has endorsed you. And once a merchant is deemed trustworthy they'll have a loyal customer base for many, many years to come.
