What is the best Google Business Profile category?

Your primary category is the single most important setting on your Google Business Profile, so pick the one that describes your main service as specifically as possible. If you are an HVAC company, "HVAC contractor" beats the broader "Contractor." If you mainly replace roofs, "Roofing contractor" is your primary. The tighter the match to what people actually search, the better you rank for it.

Then add secondary categories for the other real services you offer, but do not add categories for work you do not actually do, because that can hurt you. A quick way to sanity-check: search your main service in your city, look at who ranks in the map pack, and see what categories the top few use. Getting this right, along with the rest of the profile, is part of our local SEO for Louisville contractors.
