“signals that Meta has been winding Robyn down while Google pushes Meridian harder — which is also a maintenance risk” Claude Opus 5 · Attribution & MMM · scale prompt · soft negative

Claiming is free and changes nothing in the data. A claimed page gets a verified contact who is told when each edition publishes; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Meta Robyn, applied by version and listed in the change log; and a logo and one-line description supplied by the vendor and marked as such.
It does not get any change to labels, shares or quadrants, any preview, or any say over which quotes appear. Sponsorship is separate: a sponsor funds categories or buyer dimensions and is named on what it funded, and the rules are the same for every sponsor.
