Rank inside each engine’s own top 10 · a dash means the brand is not in that engine’s top 10.
The rest depend on which engine the buyer opens — so a rank from a single engine is not a market position.

Frequently asked questions
What does this Plumbing Services AI Search report measure?
Which plumbing services brands ChatGPT, Gemini, Google AI Mode and Perplexity name when buyers in Australia ask them for advice. We asked 317 buyer questions, each three times to each engine, and counted how often every brand appears and which websites the engines cite. Measured Sep 2026.
What does “mention rate” mean?
The share of questions where an engine names the brand in its answer. A 10% mention rate means the brand came up in about one question in ten. Every rate carries a 95% range: the interval the true value most likely falls in.
How are the top Plumbing Services brands ranked?
By mention rate, separately for each engine — pick the engine above the table. When two brands’ 95% ranges overlap, their order is not really different — tick “Only distinguishable places” to see the ranks the data can actually separate.
Why does a brand rank differently across AI engines?
Each engine retrieves from different sources and weighs them differently, so the brands it knows best differ too. Only 6 of 15 brands make the top 10 of every engine here; the rest depend on which engine the buyer opens.
What counts as a citation?
A link or source an engine shows alongside its answer. We record every cited domain, whether it appears inline or in the source list.
Why can AI mention a brand without citing its website?
Engines learn brand names from reviews, expert sites, retailers and forums, then cite those sources rather than the brand’s own pages. A brand can be named often while its own site is rarely among the sources.
What does “share of citations” mean?
Of all the citations one engine gave across our questions, the share that went to a given domain. The shares of one engine add up to 100%.
What types of Plumbing Services questions are included?
Questions real buyers ask across 8 product segments, from problem-aware to solution-aware, informational and branded ones. 75% are problem- or solution-aware; this is not a branded-prompt study.
Will I get the same answers if I ask these questions myself?
Not word for word. AI answers vary between runs, accounts and locations, which is why we ask every question three times per engine and report a 95% range instead of a single answer.
