There’s just no one-size-fits-all with marketing. How you market an online business looks different than a local business, how you market a restaurant is different than how you market a construction company, and how you market a web design company is different than how you market a retail or ecommerce business. Each one requires a slightly different strategy.

Think about implementing referral links to incentivize your subscribers to spread awareness about your brand, too. Referral links allow your current customers to promote trackable links for your business. In exchange for sending new paying customers your way, you can give them incentives like discounts, coupons, vouchers, cash, prizes or redeemable points.
