What is IDX? (Internet Data Exchange)
What is Internet Data Exchange?
Internet Data Exchange (“IDX”), also referred to as “Broker Reciprocity,” is the next stage in the evolution of MLS as the primary means of enhancing cooperation between REALTORS® to facilitate the purchase and sale of real property. IDX gives MLS Participants the ability to authorize limited electronic display of their listings by other Participants. Under IDX, brokers exchange consent to display each other’s listings on participants’ websites and using applications for mobile devices that participants control.(Revised 6.1.12) – Source: NAR
What is IDX? In short it stands for Internet Data Exchange. It is seen as an agreement between listing Agents and/or Brokers and Buyers’ Agents that allows active, pending, and sold MLS listings to be displayed online. It’s built on a policy of cooperation—real estate brokers agree to share and display each other’s MLS listings online, giving consumers one place to view the full range of available properties in a market. This mutually beneficial system, implemented in mid-2000, has profoundly impacted the real estate industry by significantly broadening the exposure of online listings.
The beauty of IDX is that, instead of sending visitors to big portals like Zillow or Redfin, IDX keeps potential buyers on your site, where you control the experience, capture leads, build trust, and promote your brand. By integrating IDX into your website, you not only showcase your own listings but also provide comprehensive, accurate MLS data that boosts engagement, improves SEO, and helps you compete online.
What is the history of IDX?
With the rapid growth of the Internet in the late 1990s, more brokerages began building their online web presence to connect directly with clients. Recognizing this shift, the National Association of REALTORS® (NAR) formed a special work group in 2000 to create policies that allowed MLS listings to be shared online while protecting professional standards and client relationships. At NAR’s 2000 Midyear meeting, the Board of Directors approved rules permitting MLS participants to display each other’s listings on their websites, launching what we now know as IDX.

It was at this point that our company, IDXCentral (Moineau Design LLC), was approached by the Tahoe Sierra Board of Realtors. They asked us to build one of the nation’s first IDX solutions. This marked the beginning of our 25-plus years of experience in developing websites with IDX.
How does IDX Work?
Technically, IDX works by creating a secure data feed between the MLS and a Broker or agent website. IDX software or plugins pull in property data—photos, details, pricing—and update it typically multiple times a day. This ensures that visitors see accurate, up-to-date listings without leaving your site. To showcase listings on your website, MLS membership is mandatory, with protocols in place to ensure compliance.
Unlike big portals such as Zillow or Trulia, which rely on syndication and may show outdated or incomplete information, IDX delivers comprehensive local MLS listings directly. Another key difference is lead ownership: portals often sell leads back to agents, while IDX allows you to capture and nurture leads yourself from all the listings on your website.
In short, IDX keeps buyers on your site, provides the most reliable data, and positions you as the trusted local resource.
Why is IDX so important for my real estate website?
Around 96% of home buyers start their search online. If your site doesn’t have an advanced IDX, those visitors will move on to one that does. IDX encourages visitors to return to your site as they check in for the latest listings. Offering the best in IDX technology and features will cater to your buyers and sellers needs. It will also help you stand out in a competitive real estate market.
