On the Internet, Web sites and search engines can be excellent sources of leads, although the process can be time consuming. Web sites, such as TechTarget.com, have evolved for the specific purpose of making it easy for personnel to obtain leads. Companies have emerged that specialize in lead generation for a fee. They perform the research, and then provide the client with a list of leads. Services of this kind have been used by insurance companies, real estate agents, wholesalers, marketing firms, private investigators, research scientists and educational institutions.
Online surveys: Consumers are asked to complete a survey, including their demographic information and product and lifestyle interests. This information is used as a sales lead for advertisers, who purchase the consumer's information if provided. The consumer may 'opt-in' to receive correspondence from the advertiser and is therefore considered a qualified lead.
