Actually that's not how they make money. Kayak for example, doesn't sell anything directly. Sites like orbitz and expedia used to charge a small commission (I remember orbitz was $5) but don't anymore. As this q/a explains, the money is made in selling hotels, rental cars and package tours.

When I came back to the US from Peru, Orbitz had by far the best deal, about $500-800 less than any other site. Oddly Kayak, which is supposed to search Orbitz, didn't show the deal I found on Orbitz.
