A method of collecting and indexing data by appending a tracking identifier (generated directly or indirectly by a tracking company) into a data file, wherein the data file is acquired from a computer system operated by a user. The data file could be data collected by a form made available through a website hosted by a web server. Additional data collected from other sources (stored as a record), such as a computer system operated by an agent, would be associated with the collected data file by an inquiry management company. The collected data and associated records are forwarded to a computer system that tracks online users and visitors. The process can marry computer collected data (other than the data file) about website activity with other activities that are independent of the website.
