Which sources do AI assistants cite about buyers agents in Sydney?
The listicles own ChatGPT, but agencies are breaking through elsewhere. ChatGPT's three most cited sources on Sydney buyers agent questions are still all rankings and directory sites, OurTop10, WhichRealEstateAgent and ANBA, while on Perplexity the most cited source in the category is now a buyers agency's own site.
Measured 2026-09-07 · Previous measurement 2026-08-26
Across 42 buying-journey prompts about buyers agents that named Sydney, NSW or Australia, these are the sources each AI engine cited most in its answers. A citation is a source the engine actually linked in a response, which makes this list a map of who each engine trusts in this category right now.
The top 3 cited sources, by engine
| Engine | #1 cited source | #2 | #3 |
|---|---|---|---|
| ChatGPT | ourtop10.com.au cited in 38.1% of answers | whichrealestateagent.com.au cited in 38.1% of answers | anba.com.au cited in 31% of answers |
| Perplexity | propertybuyer.com.au cited in 61.9% of answers | reddit.com cited in 61.9% of answers | buyersagents.com.au cited in 50% of answers |
| Google AI Overviews | propertybuyer.com.au cited in 17.1% of answers | cohenhandler.com.au cited in 11.4% of answers | facebook.com cited in 8.6% of answers |
Sample: 42 prompts, responses collected 2026-09-07 to 2026-09-07 (42 from ChatGPT, 42 from Perplexity, 35 from Google AI Overviews). Google AI Overviews has a lower response count because some prompts returned no AI Overview, and those are excluded from that engine's denominator. Excluded from citation counts: 22 prompts naming a specific business, per the TOP Score rules, and 68 prompts that stated no location (see the correction note below). Percentages are the share of that engine's responses containing at least one citation of the domain. Ties: ChatGPT's first place is shared at 16 citations by ourtop10.com.au and whichrealestateagent.com.au; Perplexity's first place is shared at 26 by propertybuyer.com.au and reddit.com, and its third place at 21 by buyersagents.com.au and cohenhandler.com.au.
Perplexity and Google AI Overviews were added to this page in the September 2026 collection, as promised at first release. Each engine keeps its own date stamp and engines are never averaged together, per the method.
Correction and rebaseline, 26 August 2026
The first version of this page, published earlier the same day, included prompts that didn't name a location. Our own checking showed engines answer location-less questions with largely overseas sources, which distorted the picture of what a Sydney buyer's question returns. We rebaselined the page the same day to count only prompts naming Sydney, NSW or Australia, and we're saying so here rather than editing silently, because that's the standard this site holds itself to. The location-less results remain interesting, and we'll publish them separately as their own finding.
What the data says
Buyers agents sell judgement and access, both hard to verify, so the engines reach for third parties who rank them rather than the agencies themselves. That makes a handful of directory and awards profiles disproportionately valuable, and it means an agency that publishes transparent fees, process explanations and honest market commentary is competing against listicles rather than rivals. That has started to shift: on Perplexity, Propertybuyer's own site is now the most cited source in the category and Cohen Handler is cited in half of its answers, proof the direct citation can be claimed.
How to read this page
- 1Citations are not mentions. This page measures which sources the engines link when they answer, not which businesses they name. Who gets named is the TOP Score, and it's measured separately.
- 2Engines disagree, so we never pool them. Each engine is reported on its own row because an average hides a total absence on the engine your buyers actually use.
- 3This is a measurement with a date on it. Models and retrieval change; a source moving between collections has not necessarily done anything. The method, cadence and limits are on the standard page.
- 4Ties are shown alphabetically and single-page sources are named. Where sources tie on citations, the table orders them alphabetically and the tie is stated under it. A domain's count can rest on a single page, often a "best of" listicle, and that concentration is itself part of what this site measures, so where it's true of a listed source we say so. Domains are counted by exact hostname, so government subdomains count separately.
