- Frequently asked questions
We read which sources ChatGPT and Google AI Mode, Google's chat-style search answers, cited in September when people asked which real estate app or service to use, from checking home values to choosing an agent.
Zillow, Redfin, and Realtor.com each appeared in more than a third of home-value and listing-search answers. No answer cited an individual listing on the five big portals.
What those pages say about your company is filled from three records you already keep: listing and sales data in the MLS, the shared database where agents list homes for sale, your agents' profiles, and your rental listings.
One boundary before the numbers: a citation is a page the answer pointed to. It is not a recommendation, a lead or a sale, and nothing here measures those.
Buyers Already Ask AI the Questions the Portals Built Their Business On
Zillow's own 2026 survey found that 82% of recent buyers use AI at least occasionally, and 61% of those used it while buying their home1.

The same Zillow survey found 70% of buyers would trust AI-generated homebuying insights, and 66% would trust its financing insights1.
Two other 2026 surveys read lower. They asked different people different questions, so a vendor's deck can quote whichever one suits it:
| Survey | Who was asked | Result |
|---|---|---|
| Zillow, Consumer Housing Trends Report1 | US recent buyers | 82% use AI at least occasionally; 61% of them used it to buy |
| Cotality, AI in Housing Survey, first quarter2 | Buyers in the US, Canada, the UK and Australia | 55% use generative AI at least monthly |
| Cotality, same survey2 | US prospective buyers | 16% trust AI to help find a home, down from 30% in 2025 |
| Bank of America, Homebuyer Insights Report3 | US prospective buyers and homeowners | 20% used AI for homebuying research in the past year |
Zillow asked people who had just bought. Bank of America's group includes homeowners who aren't moving, and Cotality's 16% is about trusting AI to find the home, not to explain the process.
Cotality's 16% is the number I'd hold onto. Learning the process is the top use in Zillow's survey, and trusting AI to find the home is the lowest figure in the table.
Zillow's Share Runs From Nearly Half to Almost Nothing, Depending on the Question
In September we asked ChatGPT and Google AI Mode the questions people ask before a move, most of them set in the US and the rest in the UK, Canada and Australia: which app shows home values, which service helps sell a house, where to rent, which lender to use, plus a block of how-it-works questions.
Every share below is of all the answers to one kind of question, both engines together, and the five-portal figures count answers that cited at least one of the five.
Zillow Alone Against the Five Big Portals, by Question
% of answers
View the data
| Label | Zillow alone | Any of the five big portals |
|---|---|---|
| Home values and listing search | 42.45% | 48.11% |
| Apartment and rental search | 19.51% | 20.33% |
| Agents and brokerages | 14.63% | 23.58% |
| How-it-works questions | 5.56% | 11.46% |
| Mortgage lenders and home loans | 1.67% | 1.67% |
| Cash home buyers and fast sales | 0.89% | 0.89% |
The two bottom rows belong to other sources. Bankrate was cited in 50.00% of the mortgage answers and NerdWallet in 44.17%. In the cash-sale answers the companies selling the service carried the citations from their own sites: Opendoor in 46.43%, Offerpad in 27.68%.
For your brokerage, the portal pages matter most on home-value, rental, and agent questions. A mortgage or cash-offer service competes elsewhere: in personal-finance publishers and cash buyers' own sites.
Zillow serves the US market, so the pooled figures understate it for a US firm. On US questions alone it was cited in 14.16% of the answers to questions asking which app or service to use, against 12.57% across all four countries.
By engine on those questions, ChatGPT cited Zillow in 13.33% of answers and Google AI Mode in 10.23%. Google AI Mode's answers carried fewer sources each than ChatGPT's in this reading, so a share on one engine isn't comparable with a share on the other: compare sources within one engine, not across the two.
Redfin Matches Zillow on Home Values, and Realtor.com Is Close Behind
On the question a brokerage's sellers care about most, what is my home worth and where do I look, Zillow isn't the only name under the answer.
Each Portal's Share of Home-Value and Listing-Search Answers
% of home-value and listing-search answers
View the data
| Label | Value |
|---|---|
| Redfin | 43.40% |
| Zillow | 42.45% |
| Realtor.com | 35.85% |
| Trulia | 13.21% |
| Homes.com | 12.26% |
Redfin and Zillow are level; the gap is under one percentage point.
Trulia (13.21%) and Homes.com (12.26%) sit well behind, and a third of the same answers also cited App Store pages, the big portals' apps among them.
Across every question we read, Zillow leads: Zillow in 10.56% of all answers, Realtor.com 8.67%, Redfin 7.07%, Trulia 1.59% and Homes.com 1.39%.
The two engines also cite different sources first. On the questions asking which app or service to use, the most-cited were:
| Rank | ChatGPT | Google AI Mode |
|---|---|---|
| 1 | Zillow: 13.33% | Reddit: 20.45% |
| 2 | Realtor.com: 11.30% | Opendoor: 16.48% |
| 3 | Bankrate: 10.74% | Google's own pages: 13.07% |
| 4 | Redfin: 9.81% | Yahoo: 10.23% |
| 5 | NerdWallet: 8.52% | Zillow: 10.23% |
ChatGPT's list is portals and personal-finance publishers. Google AI Mode's opens with forum threads, a cash buyer and Google's own pages: Reddit was in 20.45% of its answers to these questions and in 0.93% of ChatGPT's.
So a check that opens only Zillow misses Redfin, cited just as often on home values, and a check that reads only ChatGPT misses the threads Google AI Mode puts first.
Asked Which App to Use, AI Cites the Portal's Product, Never a Listing
The pages behind the citations show which part of a portal a brokerage can touch.
Which Zillow Pages the Answers Cited
% of answers citing Zillow
View the data
| Label | Value | Note |
|---|---|---|
| Homepage and app pages | 48.11% | |
| Guides and research articles | 22.64% | |
| Press and about pages | 19.81% | |
| Rental pages | 19.81% | |
| Home-value tools, such as the Zestimate | 13.21% | |
| Agent directories and profiles | 6.60% | |
| Lender directory | 1.89% | |
| Recently-sold pages | 1.89% | |
| Individual listing pages | 0% | No answer cited a listing page on any of the five big portals. |
Not one answer cited an individual listing page on any of the five portals. The questions asked which app or service to use, not about a particular home, so the answers linked to what they named: on a portal, that's the homepage, the app and the tools.
The listings reach buyers another way: through the portals' own AI search, launched one portal at a time since October 2025, from Zillow's app inside ChatGPT to Redfin's conversational search and Realtor.com's assistant.
So a buyer meets your listings through a portal twice: the general AI answer cites the portal, and the portal's own AI search reads the listing, which for an agent-listed home is the portal's copy of your MLS record.

For the Agent Question, Portal Directories and Referral Services Split the Answer
One kind of question is about your own business: which real estate service should I use to buy or sell. Its answers spread their citations across three kinds of site.
Who Gets Cited When People Ask Which Real Estate Service to Use
% of agent and brokerage answers
View the data
| Label | Value |
|---|---|
| Any of the five big portals | 23.58% |
| Any of six agent-matching services | 22.76% |
| Zillow | 14.63% |
| Realtor.com | 14.63% |
| Clever | 11.38% |
| HomeLight | 5.69% |
At least one of the five portals appeared in 23.58% of those answers, and at least one of six agent-matching and referral services, sites that pair a buyer or seller with an agent for a fee, in 22.76%. Zillow and Realtor.com were each cited in 14.63%, and Clever in 11.38%.
Clever matches sellers and buyers with agents, and its partner agents pay it a portion of their commission when a sale closes4.
For a brokerage, that citation can end in a referral fee.
Several of the questions asked for discount, flat-fee or rebate services, which is part of why flat-fee brokerages' own sites show up too.
Realtor.com's citations in these answers were mostly its agent directory and agent profile pages. Zillow's split among its buying and selling pages, its guides on choosing an agent, and its city agent-review directories.
Once a buyer or seller has a name, most contact no other agent before hiring:
37% of buyers found their agent online1, as did 35% of sellers who used an agent, including 20% through a real estate website or app5. Buyers who used an agent valued local expertise (38%) and specialized skills (33%)1; directory cards offer evidence through sales and price ranges.
Repeat your sellers' questions on a schedule to see which portal pages each engine cites.
Three Records Feed What Those Pages Say About Your Company
The parts that describe your company come from data a brokerage or property manager already keeps, and the portals say so in their own help pages.
| Record | Where it lives in your company | The cited pages it feeds |
|---|---|---|
| Listing and sales data | The MLS, entered by your listing agents or coordinator | Home-value tools, recently-sold pages, the portals' assistants |
| Agents' profiles and past sales | Your roster, each agent's MLS ID (their number in that database), the agents' own portal profiles | City agent directories and agent profiles |
| Rental listings | Your property management system | Rental search pages |
For an agent-listed home, Zillow takes corrections from the MLS feed and passes them on within 24 hours6, and the Zestimate, Zillow's automatic home value, draws on direct MLS feeds and public records7.
Zillow adds an agent's past sales automatically once the agent connects an MLS ID, and follows the MLS's record of who handled each sale8. Realtor.com syncs sold listings only from the MLS and won't take one added by hand9. One Zillow Rental Manager listing goes out to Zillow, Trulia and HotPads10.
Control over those records comes in three degrees:
- Edited directly by your people: listing data in the MLS, and each agent's contact details, photo and bio in their own portal profile.
- Connected once, then pulled by the portal: an agent's past sales, after the MLS agent ID is linked8.
- Written by others, so your people can only ask: the reviews clients leave on an agent's profile11.
The Zestimate sits outside all three: nobody can change it by hand, though the home facts behind it can be updated7.
The profiles drift most, because part of each one is kept by hand. Realtor.com ranks its directory partly on completeness: the more completely agents fill out their free profile, the higher they chart12.
It also doesn't take contact changes from the MLS: one MLS, SCWMLS, has told its members that a new phone number or email registered with the MLS does not reach the agent's Realtor.com profile, so the agent has to change it there13.
The page an answer cites is the portal's. The phone number, the sales and the brokerage name on it are your records.
Three ways the profiles fall behind, each documented by the portal or an MLS:
Errors cost trust. In Cotality's survey, one in three homebuyers said errors in listing data are unacceptable whoever makes them, AI or a person2. The platform takes that hit first, and the listing's broker is named on the page.
This work tends to land with marketing because it looks like visibility. The records live in the MLS, the roster and the property system, so the check belongs to whoever already keeps those, usually the listing coordinator or the operations manager.
What keeping them right can't promise is more AI citations; nothing we measured says so. It's worth doing because those pages are what the answers point to, and what they say about your agents comes from your records.
Each of those pages is only as current as the record behind it, and the records are already yours to keep.
Frequently asked questions
Does an AI answer that cites Zillow recommend Zillow?
No. A citation is a page the answer pointed to as a source. In September Zillow was cited in 42.45% of answers about home values and listing search, but we measured citations, not which company an answer recommended, and not whether anyone clicked.
How often do ChatGPT and Google AI Mode cite Zillow for real estate questions?
In our September research, Zillow appeared in 42.45% of home-value and listing-search answers, 19.51% about rentals, and 14.63% about agents and brokerages. It was almost never cited for mortgages or cash home buyers, about one answer in sixty and one in a hundred.
Is Zillow the most-cited real estate site in AI answers?
Zillow led the portals across all questions in our research at 10.56%, followed by Realtor.com at 8.67% and Redfin at 7.07%. The Consumer Financial Protection Bureau led all sources at 13.05%, driven by mortgage and how-it-works questions.
Do AI answers link to individual home listings?
Not in what we read. No answer cited a single listing page on Zillow, Realtor.com, Redfin, Trulia or Homes.com. The listings show up inside the portals' own assistants, such as Zillow's app in ChatGPT, which shows each home with its broker and MLS attribution14.
How many homebuyers use AI?
In Zillow's 2026 survey, 82% of recent US buyers use AI at least occasionally and 61% of those used it while buying1. Cotality found 55% of homebuyers in four countries use generative AI at least monthly2, and Bank of America found 20% of prospective buyers and homeowners used AI for homebuying research in the past year3. The surveys asked different people different questions.
Will correcting profiles earn more AI citations?
Our research does not establish that cleaner records earn more citations. The reason to correct them is that cited directories describe your agents using those records, and buyers may read them before making contact.
Does Redfin get cited as often as Zillow in AI answers?
On home values, yes. Redfin and Zillow were level on answers about home values and listing search, less than a percentage point apart, with Realtor.com close behind; Trulia was at 13.21% and Homes.com at 12.26%.
Which sources do AI answers cite for mortgage questions?
Personal-finance publishers, not portals. Bankrate was cited in 50.00% of the mortgage answers and NerdWallet in 44.17%, while Zillow was almost never cited there.
Does Google AI Mode cite Reddit for real estate app questions?
Often. Reddit was in 20.45% of Google AI Mode's answers to which app or service to use, its top source. ChatGPT's top sources were Zillow, at 13.33%, and Realtor.com, at 11.30%.
Do agent-matching services show up in AI answers about real estate agents?
About as often as the portals. At least one of six agent-matching and referral services appeared in 22.76% of answers about agents and brokerages, against 23.58% for the five big portals.
Do partner agents pay a referral service like Clever?
Yes. Clever matches sellers and buyers with agents, and its partner agents pay it a portion of their commission when a sale closes.4 For a brokerage, that citation can end in a referral fee.
How many buyers contact only one agent?
Most. 54% of buyers who contacted an agent contacted only one before hiring,1 and 67% of sellers who used an agent contacted only one.5
How fast does Zillow update a listing from the MLS?
Zillow takes corrections from the MLS feed and passes them on within 24 hours for an agent-listed home.6 The Zestimate draws on direct MLS feeds and public records, and nobody can change it by hand.7
How do an agent's past sales get onto Zillow?
Automatically, once the agent connects an MLS ID; Zillow follows the MLS's record of who handled each sale.8 Realtor.com syncs sold listings only from the MLS.9
Do homebuyers trust AI for homebuying advice?
Most say they would, in Zillow's survey: 70% of buyers would trust AI-generated homebuying insights and 66% its financing insights.1 Cotality's question about trusting AI to find the home drew 16%.2
Where do buyers first find their real estate agent?
28% of 2026 buyers first found their agent on a real estate website or app, and 37% found their agent online.1 Among sellers who used an agent, 35% found them online, including 20% through a real estate website or app.5
Does a Realtor.com profile update when an agent changes phone number with the MLS?
No. Realtor.com doesn't take contact changes from the MLS; one MLS, SCWMLS, has told its members a new phone number or email registered with the MLS does not reach the agent's Realtor.com profile, so the agent must edit it.
