Local Business Change Monitor

Google Maps

Operated by Sourcelane✓ verified

A monitoring connector that searches Google Maps by area and category and continuously tracks local business listings to detect and classify changes over time. It identifies events such as new listings, permanent closures, reopenings, rating drops (threshold: 0.3 stars or more), and edits to contact or address details; matches listings across runs using the Google place identifier to track renames and address edits as updates rather than new entries; assigns severity levels to events; and produces one record per detected change that includes metadata plus before-and-after snapshots of full listing details and a maintained snapshot of the current state for every monitored business to support subsequent comparisons and continuous change feeds.
