Displaying your property listings online has never been more important — making IDX (Internet Data Exchange) extremely valuable for anyone in the real estate industry. A study from the National Association of Realtors (NAR) found that 97% of homebuyers use the internet to search for homes and that online search is the top method that home buyers find their homes.

Surprisingly, only 69% of real estate professionals have a website. Most realtors and brokers post their listings on the Multiple Listing Service (MLS), a suite of private, regional databases for real estate brokers to share property listings. Real estate professionals pay for membership and share listings on behalf of sellers. But how do you add MLS listings to your website?

So glad you asked. This is where IDX enters the picture.

What is IDX?

Internet Data Exchange (IDX) is the system and rules that allow real estate brokers and agents to share each other’s listings. IDX software enables real estate professionals to add MLS listings to their websites.

Why IDX Matters

The purpose of IDX is to level the playing field, so smaller real estate brokers can compete with larger organizations. It also standardizes property listings across the board and fosters an environment of cooperation as brokers share their listings.

Now that we’ve clarified key terms, let’s examine how the MLS works with IDX.

How IDX Works with MLS

Since most homebuyers begin their search online, realtors and real estate agencies can create websites to market their services and connect with potential buyers and sellers. Of real estate firms, 91% feature property listings on their websites with the help of an IDX integration. You can use plugins that integrate directly with an existing site or build a new site with an IDX solution.

Your IDX solution will establish a data connection between your website and the MLS, import listings for display on your website, and run updates. This process will vary depending on which service you select.

As you set up your IDX integration, you’ll also need to choose whether to opt into a free broker reciprocity service. Enabling broker reciprocity allows other brokers to display your listings on their websites, giving your listings more potential exposure. You can also choose whether to display listings from other participating brokers.

IDX Regulations: 5 Rules to Know

The National Association of Realtors (NAR) regulates the usage of IDX. Below are a few of the rules real estate professionals should follow when using IDX:

  • You must have a seller’s consent to post their property listing in IDX.
  • Listings must be approved for display by the MLS or listing broker before they’re featured on your site.
  • Information in the listing, such as property features, cannot be altered so they appear more attractive to other agents and potential buyers.
  • If you prohibit your listings from being displayed in IDX, you cannot share other IDX participants’ listings on your site.

Top IDX Software for Brokers

Which IDX software to use for your website? The right IDX system ensures your online listings are user-friendly and interactive. Here are a few questions to consider as you choose an IDX system.

  1. Does the IDX software integrate with your current website if you have one?
  2. Do you need a new website? If so, consider a platform that will integrate well with IDX software or can custom-build a real estate website with IDX.
  3. Is it mobile-friendly? 76% of homebuyers search for homes on a mobile device, so make sure your tool is mobile-responsive.
  4. Can it host high-resolution photos and other multimedia? Homebuyers name photos as the most valuable website feature (89%), followed by detailed property info (86%) and floor plans (67%).
  5. What marketing or customer communication features do you need? Some IDX platforms have built-in communication or CRM features, while others integrate with external tools.

To help you identify your best-fit IDX platform, we’ve broken down the top five IDX platforms with pricing and the best features of each.
