Should you choose secondary categories for your GBP?

Yes, you should choose secondary categories for your Google Business Profile (GBP), but only if they are relevant to your business. While the primary category is crucial for defining your core service, secondary categories provide Google with additional context about your offerings. This helps your business appear in more specific searches and can broaden your reach to potential customers looking for related services. For example, a "Plumber" might also list "Water Heater Repair Service" and "Drain Cleaning Service" as secondary categories. Irrelevant categories, however, can confuse Google and dilute your profile's focus, potentially harming your ranking for your primary services. Therefore, choose them strategically and accurately.
