Short answer: Your primary Google Business Profile category is one of the clearest machine-readable signals of what you actually do. If it’s too broad, too narrow, or slightly wrong, AI models can miss you for searches you should be winning.
Business owners often pick a GBP category once, at setup, and never revisit it. That category is doing more work than most people realize — it’s one of the strongest structured signals available for both Maps ranking and AI recommendation logic.
Specific beats broad
“Contractor” is technically accurate for a lot of businesses, but “Roofing Contractor” or “Deck Builder” tells an AI model exactly what question you answer. The more specific the category, the more confidently a model can match you to a specific query.
Secondary categories widen your net, carefully
Secondary categories can capture adjacent services, but stacking irrelevant ones to “cast a wide net” tends to dilute relevance rather than expand it — both for ranking and for how confidently a model can describe what you do.
Check it against your actual services page
If your website’s services page and your GBP category don’t agree, that’s a small consistency gap that adds up alongside other signals AI models are weighing.
