IDX (Internet Data Exchange)

Internet Data Exchange (IDX) is the policy and technology framework that allows participating real estate brokers to display each other’s MLS listings on their websites and apps through standardized data feeds. IDX increases consumer access to inventory, drives organic traffic, and powers lead capture, while requiring strict compliance with display and attribution rules set by the MLS. For recruiting, robust IDX websites signal marketing sophistication and provide agents with high-quality listing search tools and lead funnels under their brand or team.
