You will not get our answer back, and you should not expect to. A single reply varies by the day, the account and the wording; the board is what several engines named across a fixed set of buying questions, recorded over time. What you can check is the part that matters — whether the products we say the engines name are the ones you are shown.
What decides a position
Four signals, chosen because a vendor cannot buy any of them directly. Each is a measurement of what the market does, not of what a company says.
What AI engines answer when buyers ask what to use for a job.
Where the product stands in the search results buyers actually see for the category’s buying queries — including who owns the answer box.
How many buyers search for the product by name.
Whether the product is gaining or losing ground against the others in its market, measured between dated captures rather than claimed.
A product is scored on the signals we could actually measure for it, and a signal we could not measure is left out rather than counted as zero. This is not a quality rating and not a recommendation. It measures how present and how well-regarded a product is across public surfaces — a different question from whether it is right for you.
