I just looked at the Google Hotel Finder.
Prior to looking at it, I assumed that Google would be processing the bookings and collecting fees for doing so. But it looks like Google just provides links to travel websites where you can book the room. Interestingly, in listing the websites where you can book the room the actual website of the hotel is listed last. (At least for my test city of Las Vegas, NV, it was like that.)
Why is that? Why would Google list Travelocity, Priceline, Expedia, and other travel-booking websites ahead of the hotel's own website? If Google is supposedly about relevance, then it should rank the hotel's own site first. Right?
I have a suspicion that Google is ranking the travel sites higher than the hotel site because Google might be collecting some sort of advertising fee from the booking sites like Travelocity.
Google is trying to take over everything on the internet in my opinion.
