Prospective clients don't believe claims — they believe evidence. A case study is the most persuasive piece of marketing most small businesses never get around to writing.
Start with the challenge, not your solution
Open with the specific problem your client faced, in terms a prospective client would recognize in their own situation. The more relatable the starting point, the more compelling the eventual result.
Be specific about the solution
Vague descriptions like "we improved their marketing" don't build credibility. Describe exactly what you did, in enough detail that a reader understands your process, not just your outcome.
Lead with measurable results
Numbers do the convincing that adjectives can't. "Increased qualified leads by 40% in three months" is far more persuasive than "significantly improved lead generation."
Include a direct quote
A short testimonial from the client, in their own words, adds a layer of credibility that your own writing can't replicate — even a single sentence helps.
Make it easy to find and share
A case study only works as marketing if prospects actually see it. Link to it from your proposals, your website, and your sales follow-ups.
