We spend more on Google than almost any company on Earth. When your biggest expense is your biggest competitor's ad platform, you think about that a lot.

We have 28 million listings. That's more places to stay than there are people in Australia. The supply side of our marketplace is not the problem.

The commission model was the key. Hotels pay nothing to list. They only pay when they earn. Zero risk for the hotel means everyone says yes.

Travel is the largest consumer category in the world. People will cut spending on almost everything before they cut spending on experiences.

Every pixel on our site has been A/B tested thousands of times. We don't guess. We measure. That obsession with conversion is why we win.
