Google's knowledge graph recognizes explicit subtypes like `RoofingContractor` and `HVACBusiness`. When homeowners search for emergency repairs or commercial bids, entities tagged with explicit industry schemas earn priority placement in the Google Maps 3-Pack over sites with generic business definitions. ### How do geo-coordinates (latitude & longitude) help Google Maps rankings? Providing explicit decimal latitude and longitude anchors your physical dispatch hub in Google's database. This reinforces proximity signals for localized searches, matching mobile users near your service area directly with your verified location. ### Can I use this schema on WordPress, Webflow, or custom code? Yes. The generated JSON-LD code is platform-agnostic. You can inject it into WordPress headers (via code snippets or themes), embed it into Webflow custom code embeds, or paste it directly into raw HTML/PHP templates.
