The most famous aggregator of them all doesn’t actually perform that well. The only times Kayak.com found the best rates, it did so by showing prices from Booking.com or Agoda, so why wouldn’t customers just go directly to them? Kayak never managed to find the most hotels in any price bracket (though, to be fair, it did come in second for mid-priced lodgings in Orlando), and fared particularly poorly in Hong Kong. Kayak also shared a flaw with the other aggregators: reporting a low lead price that was almost always a bit higher once you clicked through to the booking site—sometimes only by a dollar tor two, but often by $10, $20, or more. Kayak does has a solid set of filters, including a fill-in window for “nearby…” so you can name any landmark. But unless search results can be improved, there seems to be little compelling reason to use Kayak when a competing aggregator (and several direct booking sites) outperform it across the board.
