Find an error and receive a reward

If, as a user, you find a significant difference between a supplementary search result and the listing on the original source, you will receive a reward in the form of one week of free access to all our premium user services. A significant difference could, for example, be: postal code, size, or price.

Send us an email including:
A: A link to our search result.
B: A link to the listing it points to.
C: An explanation of what the error is.

We will get back to you very quickly.

As described in our terms, errors in search results cannot be completely eliminated. The challenge of completely eliminating errors can be compared to a supermarket constantly trying to remove expired products from the shelves. And just as a supermarket rewards its customers when they find expired items, we reward our users when they find an error in our search results. We take responsibility for any errors and ensure that they do not affect our users.

Our database is updated daily with supplementary information about available properties from hundreds of sites with tens of thousands of listings every day. This allows us to provide our paying users with constantly updated search results, consisting of web addresses to the places on the internet where the relevant listings are located. Our goal is for 99–100 percent of the search results to be correct in relation to the listing they link to. And we achieve that goal.

However, various errors can occur, for example:
1: The websites from which we collect supplementary data may contain typos, such as an incorrect postal code or an incorrect size in their listing. This error is then reproduced in our search results.
2: A listing on an external website may be removed between two updates. For example, if our database is updated at 12:00 and 13:00, and the listing is removed at 12:42, there will be an 18-minute period during which we link to a listing that no longer exists.
3: An error may occur in our update algorithm if an external website changes its design. The error remains until we have corrected the algorithm.

We have developed a range of systems and quality controls that allow us to detect these errors very quickly in most cases, but it is impossible to catch all errors immediately.
