Searching from your own driveway tells you very little about your rankings. Here's what a rank grid shows instead, and why your visibility drops off a few miles from your door.

Every owner runs the same test. They pull out their phone, search for the service and the town, and see their business at the top of the map. Everything looks fine. Then a customer eight miles away runs the same search, and the business doesn't appear at all.
Local results are built around the customer's location rather than yours. When you search from your own shop, Google already knows you're sitting next to the business you're looking for, so the result you see isn't the result your customers get. Drive fifteen minutes in any direction and run the search again. Most owners see themselves drop from first place to somewhere well down the page.
Instead of one search from one spot, a rank grid runs the same search from dozens of points spread across your service area and records where you appear at each one. The result is a map of your real visibility, town by town. Two things usually stand out. The drop off starts closer to home than anyone expects, often within a few miles. And the competitor beating you two towns over is rarely the one you had in mind.
Proximity is the one thing on that list you can't change. The rest you can. Build a real page for every town you want work in, with the services you run there and the jobs you've finished nearby. Keep your Google Business Profile complete and current, using the steps in our guide to the Google map pack. Ask for a review on every job, including the routine ones. Then measure the grid again in a month and see which towns moved. You don't need to rank everywhere, only in the places worth driving to.
