Internet comparison sites are internet resources that compile and list sites that deal sell products. Traditionally, they will tap into an existing database and list all sellers of a product or service.

In other words, an internet comparison site would show a customer a list of sites that sell wholesale products, and then sort out the list according to customer reviews or prices.

Most internet comparison sites will make money by receiving a commission from the merchant, or will charge each time someone clicks on a link to the merchant
