Where AI looks
The websites AI answers cited most when recommending plumbers in Portsmouth. Google AI Mode cites through its own viewer, so it names fewer sources than ChatGPT.
- checkatrade.com (opens in a new tab) both AIsin 100% of answers
- trustatrader.com (opens in a new tab) Google AI Modein 40% of answers
- threebestrated.co.uk (opens in a new tab) ChatGPTin 20% of answers
These percentages come from 9 answers from Google AI Mode and 6 from ChatGPT, asked over the last 30 days.
We list a business when AI named it in at least half its answers. Percentages show how often each was named across our recent checks. “Google AI Mode” means the AI tab in Google search, not the AI Overview above the blue links. AI answers change from one search to the next, so we ask many times. We only list businesses AI recommends — not ones it doesn't.
