Unsurprisingly, the more revenue a company has, the more leads they generate. The differences are most drastic at the highest and lowest end of the spectrum: 82% of companies with $250,000 or less in annual revenue report generating less than 100 leads per month, whereas only 8% of companies generating $1 billion in annual revenue report less than 100 leads per month.
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.
