To find the cheapest up to date offers you had to check all online agents yourself. As a solution to this, trivago.com uses its meta price comparison for hotels to bring transparency into a ‘jungle of costs’.
The innovation of the trivago technology is that you can see in an instant which agent offers which price for the sought after hotel. The users see immediately what they can save with which agent, and even those who like to book directly with a hotel should check with trivago first: most agents have better prices than the hotel itself.
