A local business needs a page of its own. The Instagram bio and the WhatsApp chat need somewhere to send a person.
The first screen should say what the business is, where it is, and what to do. For Ek Chaay that was a landing page, live in 48 hours. For Kerala Unani it was a clinic site with appointments. For Aloomi it was a Shopify store, with orders from the GCC in the first week.
Local search follows the same idea. The page has to match the place. Calicut and Kozhikode are one city with two names, and the site should not pretend otherwise. If you also serve Malappuram or clients abroad, say that on a page, not in a footer nobody reads.
I build those sites from Calicut. WhatsApp is the fastest way to describe the business.
