Your grid report is a map of your service area with a ranking checked at each point. Green means Top 3, orange means page one, red means invisible. The goal is a green centre that spreads outward.
Average rank is the headline number
One lucky green dot next to your front door means nothing. Average rank across the whole grid is the honest number, and it is the one we are paid to move.
Expect movement, not a straight line
Rankings wobble week to week while Google tests. Judge progress over a month, not a day, and compare the same grid every time.
