Every night we read the portals and the agency websites of your market. Every morning your sales, account and leadership teams see what their own data cannot show: which agents publish where, and what never reached you.

We read the websites of the largest agencies in a market and compare what they publish with what each of the top portals carries. No portal has everything, and the gap is largest where you would least expect it.
On the weakest of the top three portals it is up to two thirds. Whoever relies on one portal sees a different market than the one the agencies publish.
Markets anonymised. ProperBird research, presented at Property Portal Watch.
A portal grows on one flywheel, and it starts with inventory: buyers and tenants go where the property is, and agents pay to be where the buyers are. Your own data shows your slice of that inventory. The rest of the market is where the flywheel is decided: the agents you have never called, the customers who are drifting, the suburbs where a competitor is quietly winning. ProperBird makes that part visible, every morning.
ProperBird adds what your own data cannot see: every agent and every listing on competitor portals and on agency websites, matched to yours. One number for the whole market, and the names behind it.
Market share by suburb, hunt and farm lists, portal comparison and trends. For teams without a BI department.
The same numbers as a PDF for the management meeting, every month, with the changes called out.

Portals are most static at night, so that is when we read them. By the time your team arrives, yesterday's market is on the screen.
Behind the largest agencies of a market sit thousands of smaller agency websites. We read them at scale, deduplicate them against the portals, and tell you which listings and which agencies are missing from yours, before your competitors see them.
Listings that appeared on an agency website before any portal, one market, 2026. ProperBird agency-website crawls.
Founder-owned, part of no portal and no network. Each client's delivery, questions and dashboards stay with that client.
We collect only what portals and agencies publish.
Completeness, timing and content are monitored for every portal and every day, before you see the data.
We present our research at the industry's conference and talk about it with PropTech analyst Simon Baker. The numbers on this page are ours, measured on the agencies' own websites, and we show the method with every figure.
