In plain English
An aggregated Search Console measurement of the highest position recorded for a property or page across relevant search appearances.
Why it matters
This instrument can help answer a focused measurement question when it is connected to a real objective and read alongside relevant context.
Example
A small organisation records this signal for a defined page and period, then compares it with related instruments before deciding whether to investigate a change.
Common misunderstanding
It combines queries, locations, devices and time, so it is not an exact live ranking that everyone sees.
