Search filters play an important role in helping guests navigate this variety by refining search results to align with their needs. Yet, while search filters are designed to facilitate conversions in online marketplaces, their direct impact on driving conversions remains underexplored in the existing literature.\n  This paper bridges this gap by presenting a novel application of machine learning techniques to recommend search filters aimed at improving booking conversions. We introduce a modeling framework that directly targets lower-funnel conversions (bookings) by recommending intermediate tools, i.e. search filters. Leveraging the framework, we designed and built the filter recommendation system at Airbnb from the ground up, addressing challenges like cold start and stringent serving requirements.\n  The filter recommendation system we developed has been successfully deployed at Airbnb, powering multiple user interfaces and driving incremental booking conversion lifts, as validated through online A/B testing. An ablation study further validates the effectiveness of our approach and key design choices. By focusing on conversion-oriented filter recommendations, our work ensures that search filters serve their ultimate purpose at Airbnb - helping guests find and book their ideal accommodations.</summary>\n    <category scheme='http://arxiv.org/schemas/atom' term='cs.IR'/>\n    <published>2026-02-27T06:36:14Z</published>\n    <arxiv:primary_category term='cs.IR'/>\n    <author>\n      <name>Hao Li</name>\n    </author>\n    <author>\n      <name>Kedar Bellare</name>\n    </author>\n    <author>\n      <name>Siyu Yang</name>\n    </author>\n    <author>\n      <name>Sherry Chen</name>\n    </author>\n    <author>\n      <name>Liwei He</name>\n    </author>\n    <author>\n      <name>Stephanie Moyerman</name>\n    </author>\n    <author>\n      <name>Sanjeev Katariya</name>\n    </author>\n  </entry>"
