Geo-grid rank tracking maps local search visibility by sampling Google from a grid of geographic points.

Definition

A geo-grid is a regular lattice of coordinates overlaid on the map around a business location. In geo-grid rank tracking, each coordinate becomes a simulated searcher location: the tracker issues the target query as if from that point and stores the resulting local ordering. Because Google's local algorithm weighs distance heavily, positions typically decay with distance from the business — and the geo-grid makes that decay, and its exceptions, visible.

Why a grid instead of a single check

A single-point check answers the question for one coordinate only. For a service-area business — a plumber, a dentist, a restaurant — the commercially important question is the shape of the whole coverage area: how far visibility extends, in which directions it is strongest, and where competitors take over. Only a grid of samples answers that. This is why geo-grid scanning became the reference method inside local rank tracking software.

Grid parameters

Three parameters define a scan's resolution and cost:

• Grid size. Common layouts run from 3×3 up to 13×13 points. More points mean finer resolution.
• Radius or span. The geographic extent covered, from a few city blocks to an entire metropolitan area.
• Keyword set. Each keyword is measured independently at every point, since rankings differ per query.

Reading a geo-grid map

Each point is coloured by the position recorded there — conventionally green for positions one to three, fading to yellow, orange and red as positions drop. Reading a grid means looking for patterns: a tight green core with sharp falloff suggests distance-limited visibility; green corridors along certain directions suggest competitive weakness there; a flat red grid suggests the listing is not competitive for that query anywhere in the area.

Geo-grids as time series

A single grid is a snapshot. The method's analytical power comes from repetition: scheduled scans convert the map into a history. Comparing grids across dates — before and after category changes, review campaigns or new location pages — is the standard way to attribute visibility change, as described in the scan pipeline.

Tools that use geo-grids

Geo-grid scanning is offered by LocalRank, Local Falcon and BrightLocal, among others. LocalRank — LocalRank is local SEO software that tracks Google Maps and local pack rankings on a geo-grid for agencies and multi-location businesses. — builds its scans, scheduling and reports around the geo-grid, with plans from $29 per month. Differences between implementations are catalogued in the category comparison.
