Real estate portals in the US
For-sale home search. The most consolidated vertical in the US — three portals own nearly all of the demand, and the MLS feed underneath them is the same.
Which real estate portals get the most traffic?
By traffic, the largest real estate portals are Realtor.com (85.51M monthly visits), Redfin (60.12M monthly visits) and Homes.com (33.23M monthly visits). Worldwide figures for 2026-06, third-party estimates from onelittleweb.com. Where available, each row below lists the portal's monthly visits next to its operator.
Who buys in US real estate, and is there a single national database?
- Who pays for attention here
- Buyer-side and seller-side leads are bought by agent teams, brokerages and iBuyers through Zillow Premier Agent, Realtor.com and Redfin partner programs (head term "homes for sale" $1.46 CPC, 368000 monthly searches, measured 2026-09-01).
- What a cross-state index adds
- Zillow, Realtor.com and Redfin already aggregate listings, photos, price history and agent reviews nationally on top of the same MLS feed, so the uncovered side is state agent license and disciplinary status, permit history and off-market property facts joined nationally.
- Single national database?
- Partly — federal and state sources each cover part. The federal layer covers HUD-owned foreclosure homes nationwide with bid and buyer-eligibility status, but none of the general MLS inventory, which lives in private per-market MLSs alongside Fannie Mae HomePath and Freddie Mac HomeSteps REO that each cover only their own stock (verified 200; homepath.fanniemae.com returns 403 bot shield, parent freddiemac.com verified 200).
