Highlight your accomplishments and build social proof with case studies.
Ideally choose a client with whom you’ve had the most success, but if you want to focus on a particular aspect of your business, you can choose a client who is relevant. Consider the one thing you did best for each client, and focus on that.
Ask questions such as what was the initial problem or goal, why you were chosen for the project, and what were the outcomes.
Send your questions to a few people in different departments as they may each have a unique perspective.
Pay attention to readability - for example, use boxes, bullets or other design elements to make it eye catching and easy to digest.
Write in clear layman’s terms not technical jargon, unless your audience speaks like that. Keep it simple, no padding or fluff.
Write your case study using a structure of problem, solution and results, and include a customer quote with photo if possible.
For example, introduce your client, identify their issue, explain the plan of action you took, and present the results using data and facts. The more measurable the results, the better. For example, "we increased downloads/user retention/sign-ups/followers by x% in this amount of time”.
Present data in numbers. The details you provide will make your case study stand out from a testimonial.
If you lack data or prefer another approach, you might want to conduct a Q&A with your client. Both methods work best with quotes.
Don’t share it only on your social media pages. To reach a wider audience, look for groups and communities where the users that you want to attract are hanging out, and share some insights there. If the community rules allow it, provide a link to the full case studies for those interested in reading more.
