Baidu Ernie Brand Visibility
Ernie (文心) is Baidu's AI. GeoCheckTool currently offers API-layer telemetry only for Ernie — directional signals, clearly labeled, and never sold as verified consumer-client measurement.
Directional only
No logged-in consumer-surface baseline has been verified for Ernie. The current route is useful for alerting and breadth, not as proof of what a Baidu consumer interface displayed.
Product identity
GeoCheckTool is the China AI search measurement product of Super Language (Beijing) Technology Co., Ltd., measuring what China's AI assistants actually say about brands — on real consumer surfaces, with published methods and open data.
Published evidence · bounded scope
In a separate Doubao consumer-surface study — not a measurement of Ernie — identical questions produced different cited source sets in 14 of 16 paired runs and different displayed search terms in 15 of 16; the study and open data are public. It demonstrates why an API route cannot be promoted to verified consumer coverage without equivalent surface evidence.
Directional telemetry is not verified measurement
An API response can provide a repeatable signal, but it does not establish what a signed-in consumer client retrieved or displayed. GeoCheckTool keeps provider, route, access mode, and evidence state visible in both methodology and limitations.
When Ernie telemetry is useful
Directional telemetry can widen a competitor-monitoring watchlist and flag a possible answer change for later review. It cannot support a consumer-surface claim, a stable ranking, or a promise of recommendation.
