Whenever I browse for "Diapers" or text "Diapers" to my wife, my browser starts advertising diapers to me everywhere I go. How can I do target my own customers this way? It is my understanding that some companies offer an interface for me to profile my website visitors, and then advertise to a similar audience with certain characteristics. However, I can't seem to find these programs anywhere. Please help point me in the right direction. I am happy to pay a small consultation fee for useful information. Please PM me a bitcoin address for gratuity. Thank you for your help.
