In smaller Indian towns, Facebook is still where people look up a shop, a coaching centre or a wedding photographer before calling. The first thing they notice is how many people like the page.
Most services here add page likes and followers together (Facebook shows both numbers on modern pages). Choose a refill option for your main business page — 30 days, 90 days, 365 days or lifetime — so any drop gets topped up from your orders screen.
If your customers are local, consider Indian Facebook followers for at least part of the order.
