When a homeowner searches "emergency plumber near me" or "roofer in [town]", Google returns two types of results: the map pack (the three businesses shown with a map pin) and organic blue-link results below it. For most trade searches, the map pack captures the majority of clicks — so appearing there is the priority.
Google uses three factors to decide who makes the map pack:
- Relevance — does your business listing match what the searcher needs? This is driven by your GBP category, services listed, and website content.
- Proximity — how close is your registered business address to the searcher? You can't change geography, but you can compete on the other two factors.
- Prominence — how well-known and trusted is your business online? Reviews, citations, links, and website authority all feed this signal.
The practical implication: a roofer in a neighbouring town with a well-optimised profile, 80 reviews, and consistent directory listings will often outrank a local roofer with a sparse GBP and no reviews. Proximity matters, but it doesn't override relevance and prominence.
Understanding this framework is the starting point. Every tactic in this guide maps back to improving one of these three signals.
