Case studies can be a really effective form of marketing.

Why? Because they show potential customers that your small business has helped people just like them solve problems just like theirs.

So how do you write an effective case study? One way is to focus on the problem and your solution. 

For example, imagine you run a cleaning company. A great case study for this would be about your customers, the Smiths, who had such busy lives they didn’t have time to clean their house. Your company now cleans their house weekly, and the Smiths can relax after a long hard day at work. Problem solved.
