Zillow’s mission is to give people the power to unlock life’s next chapter. At Zillow AI — Core Search and Conversational AI, we do this by helping our customers find their dream home. Shoppers often need to look through many homes to find one that fits their unique needs. Now, we are making that process more intuitive through Guided Search, an experience which suggests personalized search refinements that help our customers narrow their searches.
Narrowing a search can be challenging with nearly 50 filters available to choose from. The large selection of filters isn’t itself the problem, as we want to provide many options for users to go deep and search on the criteria they care about. However, space on Zillow is premium real-estate (pun intended) and these filters have to be displayed within drop-down menus. As a result, it can sometimes be challenging for users to spot the filters they care most about.
We wanted to remove friction customers may experience in finding filters. To achieve that goal we added a new UI element — a limited set of buttons that we call search refinements. Through these buttons we can suggest the most relevant choice to the customers given the context. The challenge is then in ranking these refinements based on relevance.
