Ask an assistant for a plumber in your town and it will name two or three companies. That list is short, it is stable, and it is not your Google ranking.
Assistants answer from a narrower set of sources than a search engine ranks. They lean on text they can quote confidently: your own site's plain statements, directories, and pages where a third party describes you. If your business only exists as a Google Business Profile and a homepage of slogans, there is nothing for an assistant to quote.
What gets a business quoted
Statements of fact in plain sentences. "We have served Trumbull County since 2004 and we answer emergency calls 24 hours a day." That is quotable. "Your trusted partner in home comfort solutions" is not a fact about anything, and an assistant has no use for it.
Being described somewhere you do not control. A directory listing, a chamber page, a supplier's dealer locator, a local news mention. Independent corroboration carries weight precisely because you did not write it.
Answering the question the way it was asked. People ask assistants full questions. A page with a heading that matches the question and an answer directly underneath is far easier to lift than a page that buries it in paragraph six.
Ask two or three assistants for your service in your town. Write down who gets named. That list is your real competitive set for this channel, and it is often not the companies you think you compete with.
What does not work
Assistants are not counting terms. They are summarizing meaning. Repetition adds nothing and reads badly to the humans who do arrive.
Forty pages that differ only by town name give a summarizer forty copies of the same nothing.
"The best in the region" is not quotable. "Rated 4.9 across 1,000 reviews" is, because someone can check it.
The short version
Write down true, specific, checkable things about your business in plain sentences, and make sure some of them appear somewhere you do not own. That is most of it.
