Short answer
A case study tells the real story of how you helped one customer: their situation, what you did and what changed. Before writing, get the customer's written permission covering their name, photos, quotes and any numbers you will share. Let them read the final version. Never invent or round up results, and never let AI create quotes or figures that the customer did not give you.
Why case studies persuade
Prospective customers want to know whether you can solve a problem like theirs. A specific story, such as how an interior designer fitted storage into a narrow Chandigarh flat or how a CA firm sorted a trader's backlog of GST notices, answers that far better than a list of services. It also gives search engines and AI tools concrete evidence of what your business does.
Asking for permission the right way
- Ask after a successful job, when the customer is happy, and explain where the story will appear: website, social media, ads, brochures.
- Say exactly what you want to use: name, business name, photos, a quote, any figures.
- Offer an anonymous version, such as a family in Mohali, for customers who prefer privacy.
- Get the agreement in writing. An email or signed form is far better than a verbal yes.
- Agree that they can see the final text before it is published.
- Respect a later request to remove it.
Extra care in sensitive fields
Clinics, dentists, counsellors, lawyers and financial advisers handle private information. Before and after photos, health details or money details need explicit consent and often more than ordinary marketing rules require. Some professions have their own advertising codes. In India, advertising standards also expect testimonials to be genuine and claims to be supported. When in doubt, make the story anonymous and leave out identifying details.
A structure that works
- The customer and their starting point, in two or three sentences.
- The problem in their words, ideally quoted with permission.
- What you did, step by step, including anything that did not go to plan.
- What changed, using only figures the customer confirmed.
- A short quote, and photos if allowed.
- A link to the related service page.
Honesty rules for results
Only report outcomes that actually happened and that the customer agreed to share. Do not turn one good result into a promise that every customer will get the same. Add a simple line such as Results depend on each situation where readers might assume otherwise. If you have no measured results, describe the work and the customer's reaction instead; that is still persuasive.
Where AI can and cannot help
AI is useful for turning your rough notes and the customer's own words into a tidy draft, or for shortening a long story into a social post. It must not add quotes, numbers or details that did not come from you or the customer. In AI Marketing Master, result claims count as claims: unless a matching claim has been approved in your Business Profile, a draft that states a result is blocked by the quality check. Photos of people can be marked with their consent in the media library, and images with unknown rights are flagged.
What it does not do
- This page is general guidance, not legal advice. Check the rules for your profession and country.
- AI Marketing Master can store consent for people shown in photos, but it does not collect case study agreements from customers for you.
Questions people ask
Can I write a case study without naming the customer?
Yes. Anonymous case studies are common and respectful. Describe the type of customer and location in general terms and remove identifying details.
What if a customer changes their mind later?
Remove or anonymise the story promptly, including from social posts and ads where practical. Keep a record of the request.
Can I use a Google review as a case study quote?
Ask the reviewer first. A public review is not automatic permission to reuse it in your marketing.
