I am a freelance seo engineer at www.00media.com engineer and I offer a $100 bonus to all of my current clients for referrals and thought that I would do the same here. A few of you own forums or message boards that allow you to send an email newsletter to your members so what I propose is that if you would send out an email newsletter offering my seo/sem services I will pay you $100 for every client that you send my way. pm me for details or if you have any questions, thank you Chris
I can see where a visitor comes from by watching my analytics and I always confirm verbally with the customer how they found me. I might only speak with a few customers a day and I create a file for each one with their stats, I would just include from where they came.
