Google’s home listing ad format is expanding across US mobile search, giving buyers another way to find properties before they reach a portal, brokerage site, or IDX page. For most agents, the national rollout matters less than one simple question: Are their MLS listings actually showing up in it?
In Search, Home Listings Ads show for-sale property details such as price, photos, neighborhood information, and listing-agent details. The format can also place promoted buyer’s agents alongside the listing, giving consumers a way to call or message an agent.
The listings are provided through ComeHome, HouseCanary’s real estate platform. HouseCanary says the program brings broker listings from participating MLSs into Google mobile search. California Regional MLS, San Diego MLS, and My State MLS were the three MLSs publicly identified among the initial participants.
Where Google Search turns into a lead source for agents
Home Listings Ads appear on mobile Search when consumers look for homes for sale. Google says the format does not currently serve on Google Maps, and agents need an active Local Services Ads account to use it.
Eligibility depends on the listing type and the MLS feed. Active listings and some pre-market listings may appear, while rental, commercial, and land listings generally are excluded. Agents also need a verified Google Business Profile, a Local Services Ads campaign linked to that profile, and the buyer’s agent or seller’s agent job types enabled.
The cost model depends on the role. Listing brokers in participating MLSs may get attribution and click-to-contact visibility, depending on MLS rules and broker participation. Buyer agents who advertise through Local Services Ads pay for leads, not clicks or impressions. Google says pricing varies by market, and LSA reporting does not currently separate Home Listings Ads performance from other ad formats.
Who controls the listing data?
The short-term effect on portals is limited by MLS coverage and mobile-only placement. The longer-term concern is that Google could capture buyer intent before a consumer reaches Zillow, Realtor.com, Redfin, Homes.com, or a brokerage website.
That puts the focus on MLS data licensing. The issue is not just whether agents get more leads. It is how listing data is licensed, displayed, monetized, audited, and removed if a broker or MLS changes direction.
HouseCanary has said listings are surfaced under MLS rules. A program FAQ cited in news coverage also says Google does not retain listing data for large language model products or products outside the Google Listings Program. The specific MLS agreement terms, however, have not been made public.
What agents should check before spending on Google Home Listings Ads
A good place to start is with your MLS. If your MLS is not participating in the program, your listings may not appear in Home Listings Ads yet. It’s worth checking whether your MLS provides a feed to Google through HouseCanary, whether brokers have participation options, and how listing attribution is displayed.
If you already use Local Services Ads, take a few minutes to review your setup. Agents may be eligible for Home Listings Ads when the appropriate real estate job types are enabled, but keeping your profile up to date with accurate service areas, reviews, photos, and contact information can help ensure a better experience for potential clients.
For agents considering the platform, a measured approach makes sense. Rather than making major changes to your marketing mix, monitor how the program develops in your market and test performance carefully if you decide to participate. Pay attention to lead quality, response rates, and overall return on investment.
As Google expands its presence in real estate search, the practical impact will vary from market to market depending on MLS participation and consumer adoption. For now, the key is staying informed, understanding how the program works in your area, and being prepared to answer client questions as this new search experience continues to evolve.
