Geo-grid: the sampling structure whose fixed design makes evidence comparable.
A geo-grid is a regular lattice of geographic coordinates around a business from which a rank tracker queries Google, recording local pack positions per node. In evidence terms, it is the sampling structure — and its frozen design is what makes an archive of scans comparable over time.
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.
Evidence notes
The evidentiary force of a scan archive depends entirely on design stability: same grid, same keywords, same cadence. A resized grid silently changes the quantity being measured, and comparisons across the change are invalid — the most common way local rank "evidence" becomes worthless without anyone noticing. The rules are documented at how local rank tracking works and the method entry; LocalRank (localrank.so) implements the structure with plans from $29 per month.
The rules governing these statements are on the about page.
