Full method, query battery and reliability protocol: how scoring works. Machine-readable copy of this table: /index.json.
Where the grade comes from
Payment never touches the grade. Every business here is scored free, whether it has heard of us or not. We are the referee, not a vendor of the fix — we sell watching, never the ranking, never leads, never placement. An agency measuring its own AI visibility is a student grading their own exam; this table exists so somebody who isn't paid by the outcome keeps the record. A Lodestar score can only be earned.
