How to Read a Local Ranking Heatmap

The first time you see a local ranking heatmap, it looks like a weather map — a grid of colored squares over your city. Once you know how to read it, it becomes the most honest picture of your local visibility you'll ever get. Here's how to interpret a Google Maps ranking grid without guessing.

What the grid and colors mean

A local ranking heatmap is the output of a GeoGrid: a grid of points across your service area, each one a real rank check for your keyword run from that exact spot. Every cell is colored by the position you hold there:

• Green — you're in the top of the local pack (roughly positions 1–3). This is where customers actually find and click you.
• Yellow — mid-pack (roughly 4–10). You exist but you're below the fold of attention.
• Red — outside the top 10, effectively invisible to searchers standing there.

Some grids also print the exact number in each cell. The color is for pattern-spotting; the number is for precision. (For the underlying concept, see our GeoGrid glossary entry.)

Read the center first

Start at the cell over your business. It's almost always your best — often green — because proximity works hardest for the searcher standing closest to you. If your center isn't green, that's a red flag that your relevance or prominence is weak, not just your reach. Fix the fundamentals before worrying about the edges.

Then read the shape

The pattern around the center tells the real story:

• Green center fading to yellow then red at the edges — normal and healthy. Proximity decays with distance; the question is how far your green reaches. Wider is better.
• Red pockets inside a green zone — a competitor is beating you specifically there. This is the most actionable pattern on the map. Find who ranks in that cell; they're your true rival for that neighborhood.
• Lopsided green (stretching one direction) — your relevance signals are pulling that way. Great if that's where your customers are; a problem if your best neighborhoods sit on the weak side.
• Mostly red with a green speck — you're only visible right at your door. There's a large, clear runway to grow.
• Uniform yellow — you're relevant everywhere but dominant nowhere. Usually a review-velocity and prominence problem.

Turn the map into a plan

A heatmap is only useful if it changes what you do. Three moves:

1. Measure coverage, not position. Count the green cells as a percentage of the grid — that's your real visibility score, and the number to grow.
2. Attack the pockets. Pick the red cells nearest your best customer areas, identify the competitor winning them, and out-optimize for that specific area.
3. Re-run and compare. The same grid a month later, side by side, shows whether green is spreading. The trend matters far more than any single snapshot.

Read this way, a Google Maps ranking grid stops being a pretty picture and becomes a prioritized to-do list.
