We have a significant number of duplicate listings on Fotocasa and Habitaclia (the same listing offered by different real estate agencies), and we know that this situation causes frustration among users searching the portal.

At the same time, we have users complaining about not receiving responses when they contact the advertiser of a listing.

With an algorithm capable of detecting duplicate listings based on their characteristics (location, price, sq m...), we identified an opportunity for users to contact, through a single action, the duplicate listings published by different agencies.

This new feature will allow us to increase the contact ratio per user, while also enhancing their satisfaction by giving them a higher chance of receiving a response to their message.

We validate the potential of the opportunity with a Smoke Test: a modal that is displayed after an initial contact and allows the user to contact three agencies that have published the same listing.

The results of the Smoke Test were very positive:

• The modal was shown to 47% of contacts made on listings detected as duplicates.
• 32% of users who see the modal end up clicking the “Contact” button.
• And 98% of users who contact keep the 3 selected real estate agencies.

After confirming the opportunity and the potential of the functionality with the favorable results of the Smoke Test, we launched an A/B test in production on the Android and iOS apps, with equally positive results that were reflected in an increase in the conversion rate to leads and a rise in the total weekly leads.
