What is IDX?

IDX (Internet Data Exchange) allows agents and brokers to access and display MLS listing information on their real estate websites.


Also known as Broker Reciprocity, the term “IDX” refers to the software, rules and regulations which allow MLS data to show on your site. This data feed typically encompasses the listing data for properties entered into the MLS system, while IDX rules may determine where, what, and how it is displayed. If your MLS provides access to this data feed, you may use it to promote all eligible listings on your website, not just your featured listings.


IDX Broker is engineered to collect, organize and maintain your local MLS listings, allowing you to seamlessly display all MLS properties on your real estate site.

What is IDX / Broker Reciprocity?

IDX is an acronym for Internet Data Exchange. IDX is the policy instituted by the National Association of Realtors (NAR) to govern how MLS member participants can display active MLS listing information on their websites. In simple terms, IDX is the means of extracting the data from a Multiple Listing Service and delivering it to a website for public consumption. IDX is sometimes called Broker Reciprocity or IDD.

Who can participate in IDX / Broker Reciprocity?

This depends on the rules established by your local board and/or Multiple Listing Service. Since your board/MLS is independently governed, these rules might be different than rules of another boards and MLS's. Normally all Broker members (Participants) may participate in IDX/Broker Reciprocity. Agents (Subscribers) may, or may not, participate in Broker Reciprocity program depending on the rules. Sometimes individual agents can display IDX data directly on their personal websites with permission of their Broker, sometimes they cannot. Our staff can help you determine if this is the case, we just need to know the name of your local board/MLS.

Who is a "Participant"?

A "Participant" is the Broker member, or Principal Broker member of a Multiple Listing Service.

Who is a "Subscriber"?

A "Subscriber" is the non-Principal Broker member of a Multiple Listing Service (I.E. an Agent).

Do I have options for a website?

In our experience, a real estate website comes down to two basic choices: template or custom. Template: Quick to setup (some providers offer self-setup) and can be delivered with a minimal initial cost. However, it is likely your template will not be too different than the thousands or tens of thousands of other templates out there. And remember, you get what you pay for. Templates offer the least customization or site design/layout. Custom: For those willing to make the investment in a full featured custom website, you can and probably will get access to many options. A custom designed, hand built website will give you and the home buyers a richer, fuller experience. Make sure to work with a reputable business that has experience in designing a website that fits your needs and budget. We have worked with many wonderful designers who are more than qualified and we can certainly put you in contact with them.

I'm an Agent. How can I get IDX / Broker Reciprocity?

You are probably already participating since your listings are being displayed on other websites. The next step is to add IDX to your website to start capturing leads much like your competitors have been doing. We can work with you or your website developer to get IDX delivered to your website. If you really want to get a jump on the competition, consider signing up for our "Small Office IDX" service. This multi-user account can help boost the number of leads managed by your Agents and help you generate a greater sales volume as a result.

Should I build my own website?

We would counsel you to seek the help of a professional web developer. While construction of a site on your own is likely to be the least expensive option, we recommend sticking to what you do best: selling real estate. Leave the web development to the people who design and build websites for a living.

How often do you update the data?

While we are generally only required by the various MLS's to refresh the data every 12 hours, we strive to get new data sets hourly. Because of the automated email service we provide, it is important to maintain the quickest turnaround time possible.

What are FTP and RETS?

FTP (File Transfer Protocol) and RETS (Real Estate Transaction Standard) are the two types of data feeds third-party vendors, such as IDX Broker, use to aggregate MLS data and display it on approved real estate websites. Review the differences to determine which system your MLS uses.

Why would I want to let someone else display my listings on their website?

Think of it as free advertising. The more exposure for your listings the better! The more places your listings show up, the faster they are likely to sell. The bottom line is that no one gets paid until the property closes. The Internet has taken a once closed MLS system and opened it up for consumers to make faster and better informed buying/selling decisions. IDX opened the door for free advertising on tens of thousands of websites.

Why would I want to display someone else's listings on my website?

When you display these listings on your site, you give consumers one more reason to keep coming back to your site. Your site, and thus you, become a tremendous resource for home buyers in your area. Additionally, home buyers today are looking for specific information and adding IDX to your website can help answer some of the questions about what homes are available in the MLS.

How can I opt-in to my IDX / Broker Reciprocity program?

Most boards/MLS have already included all member Brokers and Agents by default. It is likely you were automatically opted-in the Broker Reciprocity program some time ago. In most cases, a Broker must explicitly ask to opt-out and sign the official paperwork to do so. Brokers who have opted-out may opt back in by submitting the proper paperwork from their board. Only in a few rare cases has the board/MLS chosen to have opt-out as the default. In these rare cases, we can help provide you, or your Broker, the paperwork to opt-in to the program.

Broker Reciprocity isn't for me. How can I opt-out?

Brokers (and supporting Agents) who decide not to participate in Broker Reciprocity may submit the opt-out form provided by their local board/MLS. However, opting-out is not a great idea because your listings will not be displayed on the Internet at all. Opting out will greatly decrease exposure for your listings, and in our opinion, should be seriously reconsidered. Furthermore, opting-out of the Broker Reciprocity will decrease the ability getting the benefit of this powerful marketing tool, which will decrease sales.

Why should I care about Broker Reciprocity?

Broker Reciprocity allows for the greatest amount of exposure for property listings. The power of the Internet, combined with the power of IDX has seriously leveled the playing field and helped to maximize the visibility of listings. If you don't display IDX on your website, potential buyers are probably not going to frequent your site. Instead, they may in favor of a competitor, who does provide these search tools. Broker Reciprocity has given the "little guy" some of the same marketing potential as the "bigger guys".

Who governs Broker Reciprocity?

Broker Reciprocity is governed at the national level by NAR. Each local board/MLS also has a set of policies of their own.

When was the Broker Reciprocity policy approved?

The NAR Board of Directors originally approved the policy on May 22, 2000. Since that time the NAR has made several revisions. IDX has been around for a few years, but recently it has become critical to the online marketing successes of real estate professionals.

What is the general level of participation in an MLS IDX Program?

Participation in any IDX program varies greatly. We have seen some cases where participation is below 50%, or as high at 100%. Participation is on the rise as more Brokers across the country choose to be involved in the program. Based on experience, we believe the average participation rates nationwide are somewhere in the 70-75% range.

Does the IDX data contain any confidential information?

No. The IDX data fields available for display to the public are approved by the board/MLS and do not contain confidential information.

Is it required to identify the listing firm information on search results?

Most of the time some information that identifies the listing firm is required. This is usually some combination of the listing agent name and/or phone, or the listing office and/or phone. Every board/MLS requires a different combination. The "rule of thumb" is that we are required to display the listing Broker or Agent name. Because of this we attempt to place this information at the very bottom of the page in an inconspicuous location.

What does VOW stand for and how is it different from IDX?

VOW is an acronym for Virtual Office Website. VOWs are an effort to distinguish property listings on the Internet from the displays governed by the IDX policies. The primary feature of a VOW is the requirement that visitors register by entering an email address and receive a password prior to accessing MLS listing data. Some MLS participants also post terms of use on their VOW's and require visitors to agree to those terms. In contrast, IDX allows brokers to include each others listings on their websites, with the consent of the other broker. The MLS data presented by IDX is slightly less detailed, and viewers of the data can choose to remain anonymous.

What IDX Is

IDX stands for Internet Data Exchange — the policy and technology that allows real estate agents and brokers to display live MLS listing data on their own websites. Established by the National Association of REALTORS® (NAR) in May 2000 and also known as Broker Reciprocity, IDX governs where, what, and how MLS listing data can be shown publicly. IDX Broker is a leading IDX software platform engineered to collect, organize, and maintain your local MLS listings, allowing you to seamlessly display all eligible MLS properties on your real estate website — not just your own listings.

An MLS (Multiple Listing Service) is the private, member-only database where real estate agents and brokers share listing data with each other. IDX (Internet Data Exchange) is the policy and technology that allows that MLS data to be displayed publicly on real estate websites. In other words, the MLS is the source of the data, and IDX is the mechanism that delivers it to your website. IDX Broker connects your real estate website to your local MLS data feed — pulling in live, updated listings so buyers can search active properties directly on your site and so you can capture leads without sending them to third-party portals like Zillow.

No — IDX Broker is not an MLS. IDX Broker is a third-party IDX software platform that connects to your local MLS and delivers live listing data to your real estate website. The MLS itself is a private, member-only database managed by your local REALTOR® board or association. IDX Broker obtains a licensed data feed from your MLS and uses it to power the search tools, listing displays, and lead capture features on your site. Think of your MLS as the data source and IDX Broker as the technology that puts that data to work for you.

IDX is also known as Broker Reciprocity. It refers to the policy originally approved by the NAR Board of Directors on May 22, 2000, which allows MLS member participants to display each other's active listings on their own websites. The policy was created to level the playing field between large and small brokerages, giving every agent and broker the ability to offer a full MLS search experience online — not just the listing agent's own properties. IDX Broker implements this policy as a technology platform, handling the data feed connection, listing display, and lead capture so agents can focus on selling real estate.

Who Can Use IDX

IDX participation rules are set by your local REALTOR® board or MLS, so they vary by market. In most MLSs, all Broker members (called Participants) are automatically enrolled in the IDX program by default — meaning you are likely already participating without taking any action. Individual agents (called Subscribers) may also display IDX data on their personal websites, but this depends on your board's rules and typically requires broker permission. If you are unsure whether you are eligible to display IDX data independently, the IDX Broker team can help you confirm — just contact us with your local board or MLS name at (541) 343-3912 or info@idxbroker.com.

In IDX terminology, a Participant is the Principal Broker member of an MLS — the broker of record who holds MLS membership. A Subscriber is a non-Principal Broker member, such as an individual agent affiliated with a brokerage. Whether Subscribers can display IDX data independently on their own websites depends on your local board's rules. In many markets, individual agents can participate in IDX with their broker's permission; in others, IDX display is limited to the Participant (broker) level. IDX Broker's team can help you determine your eligibility based on your specific MLS — reach out at (541) 343-3912.

With IDX, you can display all eligible listings in your MLS — not just your own. This is one of the most powerful benefits of adding IDX to a real estate website. When buyers visit your site, they see the full local market, which gives them a compelling reason to stay and search on your site rather than going to Zillow or Realtor.com. IDX Broker collects and maintains your complete local MLS listing data and displays it seamlessly on your website, updated as frequently as hourly. You can also highlight your own listings within that full MLS feed using IDX Broker's Featured Listings and Listing Showcase widgets.

How IDX Works & Lead Generation

IDX turns a real estate website from a digital brochure into a lead generation engine. When buyers search for homes on an IDX-powered site, IDX Broker captures their contact information through customizable registration prompts — for example, requiring sign-up to save a search or receive listing alerts. Once registered, IDX Broker tracks each lead's browsing behavior, notifies agents in real time when new leads sign up (via SMS and email), and automatically sends AI-driven behavioral emails triggered by listing activity, such as new properties matching a saved search or price changes on favorited listings. This creates a continuous pipeline of engaged, actively-searching prospects without requiring manual effort from the agent. IDX Broker plans start at $60/month.

Displaying all MLS listings — not just your own — is what makes a real estate website worth visiting for a buyer. If your site only shows your own listings, buyers will leave immediately and go to Zillow, Realtor.com, or a competitor's site to search the full market. When you display all eligible IDX listings through IDX Broker, buyers have a reason to search on your site, register for updates, and engage with you directly. Every buyer who registers on your IDX-powered site is a lead in your pipeline — one you wouldn't have captured if they had gone elsewhere. IDX turns your website from a brochure into a 24/7 lead generation tool.

When your listings appear on other agents' IDX-powered websites, you gain free advertising across potentially thousands of real estate sites in your MLS. The more places your listings appear online, the more exposure they receive, the faster they sell, and the more satisfied your sellers are. Broker Reciprocity is a rising tide that lifts all boats — your listings benefit from appearing on competitor sites just as their listings benefit from appearing on yours. If you opt out of IDX, your listings disappear from every IDX-powered website in your MLS, dramatically reducing their online visibility.

IDX, Your Website & IDX Broker Plans

IDX solutions for real estate agents typically range from around $50 to $200+ per month depending on the provider, the features included, and whether the plan covers IDX search only or a full website with IDX built in. IDX Broker is one of the most established and affordable IDX solutions on the market, with plans starting at $60 per month. IDX Broker Core ($60/month) includes essential MLS search, map search tools, lead capture, and AI-driven email automation — ideal for agents who want to add IDX to an existing website. IDX Broker Engage ($99/month) adds market reports, sold listing data, AI Smart Search, and AI Redesign. IDX Broker Elite ($149/month) includes a fully hosted, professionally designed real estate website plus all Engage features — eliminating the need for a separate website provider. All plans include a one-time setup fee, and some MLSs charge additional data fees set by your local board. You can sign up at signup.idxbroker.com or call (541) 343-3912 for a custom quote.

It depends on which IDX Broker plan you choose — and the good news is there is an option for both scenarios. IDX Broker Core ($60/month) and IDX Broker Engage ($99/month) are designed to be added to a website you already have. Whether your current site is built on WordPress, Squarespace, or a custom-built platform, you can integrate IDX Broker's MLS search, map tools, and lead capture features without replacing or rebuilding your existing site. IDX Broker Elite ($149/month) is a different offering entirely — it includes a fully hosted, professionally designed real estate website built with IDX search at its core, so no separate website is needed. If you do not yet have a real estate website, or want to replace your current one with a purpose-built IDX solution, Elite is the all-in-one path.

IDX Broker Core and Engage are IDX search solutions — they add powerful MLS listing search, lead capture, and engagement tools to a real estate website you already own or manage. Core ($60/month) covers the essentials: map search, lead capture, and AI-driven email automation. Engage ($99/month) layers on market reports, sold listing data, AI Smart Search, and AI Redesign. IDX Broker Elite ($149/month) is a fundamentally different product — it is a complete, fully hosted real estate website with IDX built in from the ground up. Elite includes everything in Engage plus a professionally designed website (Luxe or Breeze themes), custom branding, video integration, fast hosting, and built-in SEO enhancements. The simplest way to think about it: Core and Engage enhance your existing site; Elite replaces the need for a separate website entirely.

Yes — IDX Broker is designed to scale with your real estate business. You can start on Core to add IDX search to your existing website and upgrade to Engage when you are ready for market reports, sold data, and AI-powered features. If and when you need a complete website solution, you can move to Elite — which includes a fully hosted, professionally designed real estate website plus everything in Engage. Upgrades can be made at any time through the Upgrade Center in your IDX Broker dashboard, or by contacting the team at (541) 343-3912.

IDX Broker connects to your local MLS through a licensed data feed — the technical pipeline that transfers listing data from your MLS system to your IDX Broker account. The specific feed type depends on your MLS; most MLSs today use the RESO Web API standard, which provides fast, reliable, and standardized data delivery. IDX Broker handles the entire data connection process on your behalf — you do not need to configure or manage the feed yourself. Once your MLS credentials are submitted and approved, IDX Broker sets up the connection and your listing data is typically live within 2–3 weeks for supported MLSs. For questions about your specific MLS data connection, contact the IDX Broker team at (541) 343-3912.
