The websites I build for real estate agents don’t search the MLS. No map, no filters, no “3 beds, 2 baths, under $400K.” I didn’t forget it. I left it out on purpose.
The short version: Zillow already won home search, IDX search is something you rent rather than own, and if you work for a big brokerage, it has probably already given you a search site with your name on it. Your website should do the part none of those can. I’m fifty and bald. I know a fight I can’t win when I see one.
What IDX is, in plain words
IDX stands for Internet Data Exchange. It’s the arrangement that lets a brokerage show other brokerages’ listings on its own website, pulled from the local MLS. Around Knoxville that’s the East Tennessee REALTORS® MLS, formerly the Knoxville Area Association of REALTORS®.
The MLS deals with brokers, so an agent gets IDX through their broker, and it comes with rules about whose listing is whose and which disclaimer the MLS gets. Nobody builds that by hand. You pay a vendor that already has the feed, and the vendor’s server runs the search. You pay every month. Stop paying and the search goes away.
Zillow already won the search
Zillow says it averaged 239 million unique users a month in the second quarter of 2026, and it calls itself the most visited real estate website and app in the United States. That’s down 2% from a year earlier. It’s still 239 million.
Every house in your IDX search is the same house on Zillow: same photos, same description, same price, from the same MLS. Google’s own checklist asks whether a page provides “original information, reporting, research, or analysis.” A copy of a listing doesn’t. When Google picks which copy of a house to show, the one with 239 million visitors a month has a head start. One reviewer looked at ten agent sites built on a popular IDX platform in 2024 and found one getting meaningful traffic from search. It drew under 1,000 visits a month.
I’m confident in my work. I’m not 239-million-a-month confident.
Don’t send your buyers to Zillow, either
“Leave search to Zillow” doesn’t mean send people there. When a buyer taps Contact agent on a Zillow listing, Zillow’s own page says the inquiry goes to one of its Premier Agent partners. In Zillow Preferred, the invite-only version, those partners pay Zillow a percentage of their commission at closing. Put a Zillow link on your site and that button may ring somebody else’s phone.
So don’t fight Zillow on your website, and don’t hand it your people. Give them a search with your name on it.
Your brokerage probably already gave you one
Keller Williams gives its agents a website at no additional cost. Hilary’s is at hilarykilgore.kw.com, with a Search Properties button and her name and license number on it. eXp agents get a branded IDX website through BoldTrail, according to BoldTrail. RE/MAX started rolling out MAX/Tech in 2023, a kvCORE platform with customizable IDX websites, offered to its agents as a benefit of affiliation at no additional cost.
Hilary’s own website, hilarykilgore.com, which I built, has no search on it. Its See current listings button goes to a separate search site. We’re pointing that button at her KW site instead. It’s one link, which is about my speed.
If you’re with a national brand, ask your broker what’s included before you pay anybody for search.
If you want search on your own address
Some agents want search under their own domain. That’s reasonable, and it doesn’t take a new website. Two Knoxville agent sites I looked at this month do it the cheap way: the site links to a search that IDX Broker hosts. IDX Broker’s plans start at $60 a month plus a one-time setup fee it doesn’t list, and it works with almost any website. It’s still rented. The difference is that the rental is the search, not your whole website.
What a link can’t give you is the full lead machine: saved-search alerts feeding a CRM, with ads pointed at it. If that’s how you work, you want a lead platform, and you’ll pay lead-platform prices for it. That’s a different job from the one I do.
Why my sites don’t run a feed
My sites are static: plain HTML files and images. No database, no plugins, nothing to patch at eleven at night. That’s why they load fast, and it’s why the care plan after year one is $149 a year. A live MLS feed is a database that changes all day. The only way to put one on a static site is to rent somebody else’s server to run it, which is exactly what the IDX vendors sell.
I repaired hardware on Frontier, the first exascale supercomputer. I know what it takes to keep a computer running around the clock. That’s why I’m not handing you one.
What your website should do instead
The part Zillow can’t. Say who you are. Say which towns you actually know and what you know about them. Lay out how you work with buyers and sellers. Make it easy to reach you, including a button that texts you. I wrote about the pieces most agent sites skip in Thirty agent websites, zero text buttons, and about the Google-and-AI side in SEO vs. AEO. What I build is on the web design page.
Zillow has 239 million visitors a month, and not one of them can tell you why you’re the right agent. Zillow can have the houses. Your website is about the person who sells them.
Quick answers
Does a real estate agent website need IDX home search?
No. Buyers already search on Zillow, which averaged 239 million monthly users in mid-2026, and the listings in an agent’s IDX search are copies of the same MLS data. If you want search with your name on it, use the site your brokerage provides or link to a hosted IDX search.
What’s the cheapest way to add home search to an agent website?
Link to a search you already have. Keller Williams, eXp and RE/MAX all offer their agents websites with listing search. Otherwise, a hosted IDX service such as IDX Broker starts at $60 a month plus a one-time setup fee and works with almost any website.
Why not just link buyers to Zillow?
Because the Contact agent button on a Zillow listing sends the inquiry to one of Zillow’s Premier Agent partners, and that may not be you. Send buyers to a search that has your name on it.
