Not sure what field your in. When I started my business, I did pop-up events with alot of the popular businesses in town. The networking and the follows you get help build your brand. Once I built a solid social media presence, I opened my first location. Quality and service keeps them coming in. I make ice cream lol.
Word of mouth is always important but i would say, show case your work whatever it is. On fb or ig. Just keep posting and use your hashtags. Do giveways and games. Interact with your clients to get more views. Good luck
