It's difficult respond as you have asked very general questuon.
Case 1 : small business with a retail shop - idea is to increase footfall. other than normal market hours, keep your shop open for few more hours. This way your ship will more attention and visibility; may lead to increased footfall.
Case 2 : Small Office - Home Office, on case yiu best-selling consumer products, fashion apparel and similar product then simply keep.adding your contact list and pong product / item pics on what's app with price list.
With clarity on type of services, owners profile and monthly sales figure - I can suggest more ways to market small / local business.
Quite disappointed to see, without knkwing the type of small business, type of customer's they deal with -
People are only interested in promoting their services.
