The single most important word on your Google Business Profile for local search ranking is your **primary category**.
The "IS vs. HAS" doctrine in relation to Google Business Profile categories states that your categories must describe what your business *is*, not just list the products, services, or amenities it *has*. For example, a motel with a swimming pool *is* a "Motel," it *has* a swimming pool. Choosing "Swimming Pool" as a category would be a mistake.
A business can use one primary category and up to nine secondary categories on their Google Business Profile, making a total of ten categories.
