Abstract: A method of accumulating a personalized list of products viewed by a user on different website domains includes providing a first embedded code on a first website domain and a second embedded code on a second website domain in which the first website domain is different from said second website domain. Each of the embedded codes allows a specified third party server to communicate interactively with the user. The method further includes automatically accumulating a personalized list of products viewed by the user in a database on the specified third party server, wherein the personalized list includes at least a first product and a second product, wherein the first product is on the first website domain and the second product is on the second website domain.
