Not all of your site visitors are ready to talk to your sales team or see a demo of your product. Someone at the beginning of the buyer's journey might be interested in an informational piece like an ebook or a guide, whereas someone who's more familiar with your company and near the bottom of the journey might be more interested in a free trial or demo.
Sales leads are generated on the basis of demographic criteria such as FICO score (United States), income, age, household income, psychographic, etc. These leads are resold to multiple advertisers. Sales leads are typically followed up through phone calls by the sales force. Sales leads are commonly found in the mortgage, insurance and finance industries.
