Frequently asked questions
What does this Gemini Home Services report measure?
Which brands Gemini names when buyers in the United States ask Home Services questions, and which websites it cites in those answers. It covers 7 Home Services markets and 2,354 buyer questions, each asked 3 times, and sets Gemini next to ChatGPT, Google AI Mode and Perplexity on the same questions.
“Mention rate” — what does it mean?
The share of buyer questions where Gemini names the brand. Each question is asked 3 times, and every rate carries a 95% range: when the ranges of two brands overlap, their ranks are not really different.
What does “market concentration” mean?
How much of all brand mentions in a market go to its three most-named brands. When the top three hold most of the mentions, the market is highly concentrated and hard to break into; when mentions are spread over dozens of brands, it is open.
Which Home Services markets are included?
7 US markets measured on Gemini: Electrical Services, Heating & Air Conditioning, Pest & Wildlife Control, Plumbing Services, Pool & Spa Services, Roofing and Solar & Battery Installation. Each market has its own question set, its own brands and its own ranking.
Why are only 20 brands shown per market?
Radar publishes the top 20 brands of each engine in each market. A brand missing from a table here can still be named by Gemini — just below its top 20.
What counts as a citation?
A link to a website that Gemini shows as a source in its answer. We count every cited URL and group them by domain.
Why can Gemini mention a brand without citing its website?
Naming a brand and citing a source are separate. Gemini often recommends a brand while linking to a publisher, a retailer or an association that wrote about it. That is why the brand ranking and the sources table can tell different stories.
Will I get the same answers if I ask Gemini these questions myself?
Not word for word. Answers vary between runs, accounts and locations, which is why every question is asked 3 times and the results are read as rates with a 95% range. A single answer you get yourself is one sample from the same spread.
