AI visibility is more stable on some providers than others
When comparing the same brands week over week, some providers barely move while others swing by double-digit percentage points. Across three weeks in May, one provider held steady within a 5 pp corridor for every tracked brand; another swung by up to 29 pp for a single brand over the same period. Both are scanned twice daily, so the difference is not measurement noise: it is platform behaviour. If your visibility score jumps or drops, check which provider moved before you change your content.
