If you’re in the real estate world, you’ve probably heard the term “IDX site” — but what is an IDX site?
An IDX (Internet Data Exchange) site is a real estate website that connects directly to MLS (Multiple Listing Service) data. This means your site can automatically show the latest property listings — just like big-name platforms — but with your branding. It’s a powerful tool that helps you attract and engage potential buyers.
Instead of sending clients to third-party sites, an IDX site lets you keep them on your website. Visitors can browse listings, filter searches, save favorites, and even request showings — all from one place. This not only boosts your credibility but also helps you capture leads and grow your business.
For real estate agents and brokers, having an IDX site is more than a bonus — it’s a must-have. It shows you’re serious, professional, and ready to serve clients better.
By the end, you’ll understand exactly what an IDX website is and how it can help you grow your real estate business in Canada.
What is an IDX Website? (The Complete Definition)
Let’s start with the basics. An IDX website is a real estate website that connects to the MLS (Multiple Listing Service) and shows live property listings — including listings from other agents and brokerages.
So, what does IDX stand for in real estate? It stands for Internet Data Exchange. This is the technology that lets agents share listings and display them on their websites, following the rules set by their local MLS.
Here’s how it works:
- The MLS is a private database where real estate agents list properties.
- IDX lets you pull those listings and show them on your own website.
This means your website stays updated with the latest homes for sale — without you lifting a finger.
For example, if you’re a real estate agent in Toronto, an IDX website lets you display all active listings in your area, even if they belong to other brokerages.
It’s a smart way to keep clients on your site, build trust, and generate more leads — all while offering a great home search experience.
What are the Key Characteristics of IDX Sites?
An IDX-enabled website comes packed with features designed to help real estate professionals attract and engage buyers online. Here’s what makes these sites so valuable:
1. Display of Active MLS Listings
Your website can show live property listings directly from the MLS. This includes homes listed by other participating brokers, giving your visitors access to a wide range of options — all in one place.
2. Search Functionality
IDX sites offer powerful search tools. Visitors can easily filter listings by price, location, property type, number of bedrooms, bathrooms, square footage, and more. This helps buyers find exactly what they’re looking for — fast.
3. Detailed Property Information
Each listing includes rich details such as high-quality images, property descriptions, pricing, maps, neighborhood info, and more. It’s the kind of content today’s buyers expect when house hunting online.
4. MLS Compliance
IDX technology follows strict rules set by your local real estate board or MLS. This ensures that all listing data is displayed legally, fairly, and accurately — protecting both agents and consumers.
Because of these features, IDX websites are one of the most powerful tools in modern real estate marketing — helping agents build trust, generate leads, and close more deals.

IDX vs. MLS: What’s the Difference?
It’s easy to mix up MLS and IDX — they work closely together, but they serve different purposes.
MLS (Multiple Listing Service)
You might be wondering what is MLS IDX. The MLS is a private database where licensed real estate professionals — like agents and brokers — upload, share, and access property listings. It’s used behind the scenes to manage listings, update details, and collaborate with other agents.
Only authorized real estate professionals can log in and use the MLS.
IDX (Internet Data Exchange)
Do you know what IDX websites are? IDX is the public-facing technology that takes MLS data and shows it on real estate websites. This lets buyers search and view available homes directly on your site — without needing access to the MLS itself.
IDX makes your site more useful and keeps visitors coming back.
- The MLS is like a warehouse where all the listings are stored.
- IDX is the showroom where buyers can browse and explore those listings online.
Together, MLS and IDX work to help agents manage data privately while making it easy for buyers to search listings publicly — a powerful combo for real estate success.

How IDX Websites Work: The Technical Breakdown
To fully understand what is IDX in real estate, it’s important to know how IDX websites actually function behind the scenes. While it may sound technical, the process is quite simple when broken down into a few easy steps.
Here’s how IDX integration works:
1. Data Feed Connection
Your website connects to your local MLS through something called an IDX feed (also known as an MLS IDX feed). This connection allows your website to pull listing data from the MLS database.
2. Listing Display
Once connected, the IDX feed sends property details — such as photos, prices, descriptions, and status — directly to your website. These listings are then displayed in real-time for your visitors to view.
3. Search Functionality
Your website includes built-in search tools so users can filter listings by location, price, number of bedrooms, square footage, and more. This gives buyers a smooth and personalized home search experience.
4. Automatic Updates
The IDX feed updates frequently — often every 1 to 24 hours. This means if a home is sold, goes off market, or has a price change, your website will automatically show the most up-to-date info.
Know Popular Types of IDX Solutions
When it comes to setting up IDX, there’s no one-size-fits-all. Canadian real estate professionals can choose from several options based on their needs, budget, and technical skills. Here are the most common types:
1. IDX Plugins
These are add-ons for platforms like WordPress — popular ones include DSIDXpress and Realtyna. They’re easy to install and great for smaller websites or agents just getting started.
2. Full IDX Websites
These are custom-built from the ground up with advanced search features, full branding, and design control. Ideal for agents or brokerages who want a unique and professional online presence.
3. iFrame Solutions
These are the easiest to set up. They simply display listings in a frame on your site. However, they offer limited SEO benefits and less control over design.
4. REST API Integration
The most powerful and flexible option. It gives you full control over how listings appear and lets developers create a completely tailored user experience.

5 Steps to Implement IDX on Your Website
If you’re learning what IDX integration is and how to set it up on your website, don’t worry — it may seem technical at first, but it becomes much easier when you follow a clear process.
1. Choose an IDX Provider

3. Install the IDX Solution
Depending on the provider, this could mean installing a plugin (for WordPress), integrating an API, or working with a developer for a custom solution.
4. Configure Search Settings
Customize the way listings appear. Choose filters like price range, location, property type, and more. Tailor it to your target audience to improve their browsing experience.
5. Test and Launch
Before going live, test everything. Make sure listings are displaying correctly, search filters work, and the site loads smoothly.
Common Challenges and Solutions
