Lead generation is the process of finding people (leads) who’re likely to become your customers immediately or in the future. “Finding” people implies finding information about people, like their name, email ID or organization’s name, all of which you can use to initiate a business relationship with them. You can generate leads organically and/or by spending money, depending on your resources.
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.
