what idx promises
An IDX feed puts live MLS listings on your domain. The pitch writes itself: buyers love searching for homes, so give them search on your site and they will stay, browse, and register. Almost every realtor website vendor sells it, usually as a monthly line item.
We ended our first article on realtor websites by saying a property search feature is nowhere among the jobs a site actually performs. This is the promised explanation, built on the same NAR 2025 Profile of Home Buyers and Sellers.
search won, and that is the problem
Buyers really do live in search. In 2025, 52 percent of buyers found the home they eventually purchased on the internet, against 27 percent who found it through their agent. In 2001, those figures were 8 and 48. They have traded places. Buyers ran that search over a median of 10 weeks, and 70 percent did it on a phone or tablet.
The IDX pitch reads those numbers as proof your site needs search too. But the searching already happens somewhere: in portal apps, with saved filters, instant alerts, and years of habit.
Here is the paradox. The more buyers search, the less your search feature matters. The searching goes where the search is best, and that will never be a rented widget on an agent’s site.
a commodity cannot differentiate you
IDX is the same MLS feed every other IDX site in your market rents. Identical inventory, identical photos, identical data, refreshed on the same schedule. The only difference is the interface, and yours is the rented one. A buyer on your search page is one tap from a better version of the same thing.
A website stands out with what only you have. IDX is the one feature that is, by definition, the same as everyone else’s.
what buyers cannot get from a portal
The survey shows where agents still hold ground. Agents were an information source for 85 percent of buyers, more than any website or app. And buyers called finding the right property the most difficult step of the whole process, at 56 percent. Inventory is solved. Judgment is not.
Your site should sell the thing a portal cannot: your judgment. Which homes are worth a visit. What a good block looks like. What you know because you were inside the house.
the alternative: add your listings yourself
There is a version of listings on your site that beats the portals, and any agent can build it. Add them yourself.
Your active listings first. You only have a handful at a time, so each one can get real attention: photography shown at full size, the details in order, the things you would say at the showing written down. A page built by hand for one home is a better experience than any feed template, because a feed cannot pay attention.
Then your closed sales. A simple track record: the address, the sold price, the dates, which side you represented. It shows a referred buyer you are active right now, in the neighborhoods they care about, and no portal will ever build that page for you.
There is data behind this. In the survey, 34 percent of buyers called detailed information about recently sold properties very useful, and neighborhood information matched it at 34 percent. Both are pages you can own without renting anything.
One caution. Follow your MLS display rules when you post sold data. For sales where you were not the listing agent, stick to the facts of the listing, and do not reuse another agent’s photos without permission. The facts make your point fine on their own.
so who actually needs idx?
Scale answers this question.
- Teams and high-volume agents. Past a certain size the monthly cost is a rounding error, and some clients expect a search tab on your site even if they never touch it. Meeting that expectation is a fair reason.
- Brokerages. Yes. A brokerage site speaks for every agent and every listing in the shop. A feed belongs there.
- Solo agents under $20 million a year in production. You do not need it. Spend the money and the attention on the pages above.
Unless you want one anyway. That is allowed, and if you do, we will build you the best IDX experience you have ever seen.
questions agents ask
will visitors leave my site if they cannot search listings?
The visitor who wants to search was never staying. Buyers named agents their most frequently used information source, at 62 percent, ahead of their own phones and tablets at 53 percent. Buyers grind through inventory on the portals and come to people for judgment. The visitor your site exists for came to check you out. Make that easy, and put nothing in the way.
does idx at least help my seo?
No. Those listing pages are copies of the same listings on every portal and every other IDX site in your market. Search engines pick one winner per listing, and it is almost never the smallest site in the pile. The duplicate pages do nothing for you, and a pile of them can drag down the few pages that are actually yours. The SEO that does work for an agent site is a different list.
can i post sold listings if i was the buyer’s agent?
Generally yes, with care. The sale itself, the price, the date, and which side you represented are facts, and most of them are public record anyway. The photos are not yours; they belong to whoever commissioned them. Use your own, or none. And display rules vary by MLS, so read yours before you build the page.
