Testimonials and case studies on your website

Short answer

Testimonials and case studies work on your website when they are specific, attributable and placed next to the decision they support. A review that names the job, place and result, beside the call to action on the relevant service page, does far more than a page of anonymous five-star quotes.

• Specific beats glowing: job, location, problem and result in the customer's words.
• Attribute every testimonial: name, town or company, with permission.
• Put proof on service pages and near every call to action, not on a separate page.
• Short case studies follow problem, approach, result, with a real number if you have one.
• Publish genuine reviews only; UK law bans fake and concealed incentivised reviews.

Testimonial or case study: what is the difference?

A testimonial is a short statement from a customer about their experience with a business. A case study is a structured account of a specific piece of work, describing the customer's problem, what the business did and the result, usually with more detail and evidence.

Testimonials build general trust quickly. Case studies prove capability for a particular kind of work and suit larger or more complex purchases where buyers want to see how you think.

Why do most testimonials not persuade anyone?

Most testimonials fail because they are vague. "Great service, would recommend" could have been written about anyone, and visitors know it. They also fail when they are unattributed, or when they sit on a testimonials page most visitors never open.

Persuasive proof answers the specific doubt a buyer has at that moment: will they turn up, will it cost what they said, will the result last, will they deal with problems properly.

How do you collect testimonials that are specific?

Ask better questions at the right time, usually straight after a successful job. Instead of asking for a review, ask two or three questions and use the answers, with permission.

• What were you worried about before choosing us?
• What happened during the job that stood out?
• What is different now the work is done?
• Can we use your name, town and a photograph of the work?

• Website trust signals that make visitors enquire

How should a case study be structured?

Keep case studies short and scannable, between 300 and 700 words for most SMEs, and follow a predictable structure so buyers can compare them.

• Headline with the result: Kitchen refit completed in nine days, on the fixed price.
• Client context: sector, size, location, with permission to name or anonymised.
• The problem in their words.
• What you did, in three to five steps.
• The result, with a real figure and time period if you have one.
• A quote from the client and photographs of the work.

• How to write a service page that wins enquiries

What are the UK rules on reviews and testimonials?

The Digital Markets, Competition and Consumers Act 2024 bans fake reviews, commissioning fake reviews, and publishing reviews in a misleading way, including concealing incentivised reviews. The CMA has published guidance for businesses that publish consumer reviews and can fine businesses directly.

In practice: use genuine reviews only, get permission to use names and photographs, disclose any incentive, and do not selectively hide negative reviews in a way that gives a misleading overall picture. The ASA's advertising code also requires that testimonials are genuine and supported by evidence.

When should you anonymise proof?

Anonymise when clients are bound by confidentiality, work in sensitive sectors such as healthcare or finance, or simply prefer not to be named. An anonymised case study that gives sector, size and region, such as a logistics firm with 40 staff in the Midlands, still carries weight.

The trade-off is credibility. Named proof is more persuasive, so ask every satisfied client, and use anonymised examples to fill gaps rather than as the default.

What does this look like in practice?

A pattern in hospitality and trades: dozens of strong Google reviews, none of them on the website, and a testimonials page with five undated quotes signed with initials.

Pulling the most specific recent reviews onto each relevant service page, with names and towns where customers agree, and linking to the full review profile, puts proof where decisions happen. It uses what the business already has and costs almost nothing.
