Google Maps Competitor Density Mapper

Google Maps

Operated by Sourcelane✓ verified

Performs grid-based Google Maps searches for a specified business category across a city, neighborhood, or trade area and produces a point-in-time, cell-level competitor density snapshot optimized for heatmapping and spatial analysis. For each grid cell the connector returns geographic coordinates, a sampled competitor count (up to ~40 results per cell), aggregated maturity signals (average rating and average review volume), and the top businesses in the cell ranked by review volume (includes business name, rating, review count, and address); each record is tagged with the searched category and a timestamp. Core technical capabilities: systematic grid search across a configurable radius and grid resolution (up to 7×7 cells per run), sampling of multiple result pages per cell, per-cell aggregation of counts and rating/review metrics, and extraction of top N businesses per cell.
