See who makes the answer.
Inspect whether your business is named, how it is described, and which competitors appear beside it. Keep the original question, engine, location, and date in view.
Follow the cited sources.
Open the pages explicitly linked in the response and examine their context. A mention names your business; a citation links to a source. One can happen without the other.
Keep a record of what changes.
Compare recorded answers using the same question and conditions. Look for changes in recommendations, cited sources, and competitors. One response is a snapshot, not a permanent ranking.
