Targeted zip codes are usually the primary determinate for pricing online home search engine leads. Online ads on sites like Realtor.com and Zillow are typically priced by cost per impression or cost per click. Cost per impression is the number of times an ad is seen, while cost per click is the number of times an ad is clicked on. The more buyers and sellers who search within a specific zip code, the more it will cost to advertise within that zip code.
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.
