Sample: 35 answers from 12 of the 12 assistants asked, on 3 question phrasings, edition of October 1, 2026. 22 unverifiable names (likely hallucinations) dropped.

Business links point to each company's own website — found in what the assistants cited or wrote, a business listing that returned this exact business by name, or the business's own domain — and every one was loaded and checked to name that business before it was published. A name without a link is one we could not confirm.

Asked the ways customers actually ask

The same assistants, the same week, three phrasings of one need — ranked separately. A business that wins “best” but loses “most affordable” is losing a different customer each time.

Is your business in this answer?

12 assistants answered “Who are the best solar installers in Riverside, CA?” this month and named 25 solar installers in Riverside, CA. Which side of that list you are on decides whether a customer asking that question ever hears your name.

On the list, and want to be higher?

Rank here is set by how many assistants repeat your name and which sources they read to decide it — the 25 sources above are the ones that shaped this answer. Our platform measures exactly that for one business: the same 12 assistants, daily instead of monthly, which of those sources you appear on and which you don't, and every fix tracked until the answer changes.

How is this ranking measured?

Fixed, unbranded consumer questions — including "Who are the best solar installers in Riverside, CA?" — are put to the same assistants every month.

No business can pay to appear or to rank higher.

The prompt set is fixed and unbranded, so month-over-month movement means the assistants changed their answer — not that we changed the question.
