IDX Website Basics For Real Estate Agents
IDX lets you show MLS listings on your own website. It can help, and it comes with rules and costs. This is a plain explanation of how it works and how to decide.
Newel Guides · Updated September 2026What IDX Means
IDX stands for Internet Data Exchange. It is the set of MLS policies and technical feeds that let participating brokers display other brokers' listings on their own websites. In practice, IDX is a property search on your site that pulls listing data from the MLS.
How It Works
- You are a member of an MLS that offers IDX, and your broker has signed the IDX agreement.
- A provider takes the MLS data feed and turns it into a search you can embed in or link from your site.
- Visitors search, view listings, and often create an account to save homes or set alerts.
- Those sign-ups become leads for you.
What Your MLS Requires
Every MLS sets IDX rules. Common ones include showing the listing brokerage name, refreshing data at set intervals, hiding some listings if a seller opts out, limiting how much data you display, and prohibiting changes to listing content. Your MLS or broker will give you the current policy. You usually cannot just paste a feed from a random source. It has to be an approved vendor or an approved method.
Ways To Add Search
- Brokerage or platform search. Your brokerage provides a search that you link to from your site.
- An IDX plugin or embed. A vendor supplies a widget or full search pages on your domain.
- A full IDX website. The whole site is built on a platform that includes search.
What To Weigh
- Cost. Setup plus a monthly fee. Quotes for integration on a custom site vary widely, so get written pricing.
- Speed. Some embeds slow the page. Test before you commit.
- Ownership of leads. Find out who owns the sign-up list and whether you can export it.
- SEO value. IDX pages on your domain are often duplicates of what portals show, so they rarely rank on their own. Original content about your area does more for search.
- Your workflow. Search helps most when you follow up with the people who sign up.
Do You Need It?
If clients find you by referral or social media and you send them to a search that already exists, you may not need IDX on your own domain. If you want to capture buyers who are browsing, and you will follow up fast, it can be worth the cost. Many agents start with a simple site and add search later.
Where Newel Fits
Newel builds the website itself: design, pages, forms, and your domain. MLS search through IDX comes from your MLS and its approved vendors, and it is not part of the standard packages. If you need it, say so in the intake form so it can be scoped as a Custom Build or linked to your brokerage's search. See website pricing and start a build.
Questions To Ask Your MLS Or Vendor
- Does my MLS allow this vendor?
- What data is displayed and how often is it updated?
- What disclosures must appear on each listing?
- Who owns the account sign-ups?
- What is the total cost in year one and year two?
- What happens to the search if I switch brokerages?
Content Around The Search
If you add IDX, do not stop at the search box. Write a few pages that a search cannot provide: what living in a specific community is like day to day, a guide to your local buying process, and notes from recent closings you handled with client permission. These pages give visitors a reason to trust you and a reason to submit their contact information. They are also the pages that can rank in search for local terms, since the search results themselves usually duplicate portals.
Common IDX Mistakes
- Signing a long contract before confirming the vendor is approved by your MLS.
- Assuming every listing in the area will show. Some sellers opt out of IDX display.
- Forgetting the required attribution and disclaimers, which can trigger a compliance notice.
- Letting sign-up leads sit without a reply. The search only pays off if you follow up.
- Building a site that is only a search box and has nothing about you.
