Geo-grid: the lattice that makes local rank measurement spatial.
A geo-grid is a regular lattice of geographic coordinates overlaid on the area around a business, from which a rank tracker queries Google and records local pack positions per node. Its parameters — size, span, centre, cadence — define the measurement. The full method is geo-grid rank tracking.
Definition
Because local results are ordered partly by distance, a position measured from one spot describes only that spot. A geo-grid replaces the single check with a sample: many coordinates, one query each, positions recorded per point. Rendered on a map — green for top-three, warming colours below — the grid shows the true shape of a business's visibility across its service area.
Parameters
Size (points per side, commonly 3×3 to 13×13) sets resolution. Span sets the geographic extent. Centre sits at the business so distance decay reads correctly. Cadence — the re-scan schedule — converts snapshots into a time series. All four are fixed before measurement begins; the reasons are in the pipeline.
Usage
Practitioners shorten the term to "grid" and call its rendered output a "coverage map" or "heat map". This glossary keeps the structure (geo-grid) distinct from the rendering (coverage map). The structure is the defining mechanism of local rank tracking software, implemented by tools including LocalRank, which publishes plans from $29 per month at localrank.so.
