Internet Data Exchange (IDX)

Simply, what is Internet Data Exchange (IDX)?

IDX gives MLS Participants the right to display limited property information from the MLS database on their Internet websites. The Berkshire IDX Solution was launched on May 1, 2002.

How can you utilize the MLS data on your own website?

Every Broker has the ability to enhance their public website with a compilation of listing information and offer clients and customers the ability to review listing data on their own. As a listing broker, you are assured that your name and phone number, as well as accurate listing information is consistently displayed and updated on all web displays. Every broker also has the ability to opt out of this reciprocal advertising agreement.

Internet Data Exchange is accomplished via a smart-frame solution, which is a free, secure website designed to protect the accuracy of the MLS information and uniformity of updates and display. A website frame is a combination of two or more web pages that have been designed to work together.

Every office that chooses to participate in the IDX system can ‘smart frame’ MLS data on their office website. Additionally, each participating broker can authorize any individual agents to use the IDX data on separate sales associate websites, provided all agree to adhere to the rules and regulations of the service, IDX and the Board of Realtors. If an agent is interested in taking advantage of this option, they should speak to the Broker in their office and obtain their signature on the Associates Authorization form.

Technical Information

Making a Transition

If you have a website and would like to feature a free search of the MLS database of listings (IDX: Internet Data Exchange) then you will need to agree to the rules and request permission to use the data.

Complete the latest “MLS Internet Data Exchange Smart Frame Authorization for Use” form, provided below.

According to policy, use of IDX is limited. The MLS limits the right to display other Participants’ listing to licensed Real Estate Brokers who hold participatory rights in the Berkshire MLS. Participants may provide the Multiple Listing Service with a written release granting an agent in good standing with the ability to utilize the smart frame MLS solution, provided that the Participant acknowledges supervisory responsibility for said agent.

Any member that wishes to display the Berkshire real estate property search on their own website must complete the Authorization of Use form prior to including it on your website. All associates must also obtain their broker’s permission, and a place for their signature is included on the form.

If you would like to view a smart frame solution in action, please view the Berkshire Board’s display. The creation of this page took approximately 1 hour and is a very basic example of this system in action.

IDX Background:

The National Association of REALTORS® has issued a mandate that all Multiple Listing Services adopt an IDX policy. This policy requires that each MLS must enable their Participants to display on their public website, aggregated MLS listing information through either downloading and placing the data on Participants’ websites or by framing such information from the MLS or association website.

There are several very successful MLS IDX programs in the country that were the inspiration for this new policy. After one year of launch, most MLS’s are reporting 100% listing office participation.

By adopting internet policy that is fair to all members, it places all on a level playing field for web content and is a proactive approach to ensuring protections are in place to avoid ethics issues or lawsuits.

How will this affect you?

You will have the ability to enhance your public website with a compilation of listing information and provide your clients and customers the ability to review listing data on their own.

As a listing broker, you are assured that your name and phone number, as well as accurate listing information is consistently displayed and updated on all web displays. As a listing broker, you also have the ability to opt out of this reciprocal advertising agreement.
