How the list is computed, what the two score parts mean, and why placement can’t be bought.
The list is computed at request time from published Voice AI providers mapped in the RankGlobal dataset worldwide. Order is the specialist score: how focused each firm is on this area and how much of it its own website shows, then client ratings and reviews. It is not a stored editorial pick.
No. Placement cannot be purchased. Commercial relationships do not change rank.
Absence from this shortlist means the firm is not a published provider mapped to this scope in RankGlobal, not that it does not exist. Coverage grows as profiles and reviews are added.
