Service-area vs. location pages: which do you need?
How you handle local pages depends on your business model. A shop customers visit is different from a plumber who travels to them — and Google treats them differently too.
Location-based businesses
If customers come to you (a clinic, a restaurant, a shop), your physical location matters. Focus on your address, your Google Business Profile, and pages for each actual location you operate.
Service-area businesses
If you go to customers (trades, mobile services), you serve an area rather than a storefront. Create genuinely useful pages for the areas you cover, and set your service area correctly in your Business Profile.
Either way: be genuine
Whichever model fits, the rule holds — make each area page truly useful, not a thin duplicate. Relevance and honesty win local search.
