Most property businesses have testimonials on their website. They say things like 'excellent service, would highly recommend' and sit alongside a five-star rating. They are better than nothing. But they are far less persuasive than a well-written case study, and the gap between the two is visible in enquiry quality.
What a testimonial does
A testimonial provides a social proof signal. It tells a prospective client that someone else used this company and was satisfied. That is a useful function. It reduces a small part of the trust deficit that every unfamiliar company faces. It is not, on its own, persuasive enough to make someone choose you over a credible alternative.
What a case study does differently
A case study tells the full story: what the client needed, what was done, and what the result was. It gives context that a testimonial cannot. It allows a prospective client to see themselves in the situation described, which is one of the strongest persuasion mechanisms available. When a visitor reads a case study and thinks 'that sounds exactly like my situation', the trust that takes weeks to build through other means is established in minutes.
The anatomy of a case study that works
- Service and location: specific enough to be relatable and searchable
- The challenge: what the client needed to solve, in concrete terms
- What was done: specific enough to demonstrate genuine expertise
- The outcome: numbers wherever possible, not adjectives
- A short client quote if available
Why numbers matter more than adjectives
'Great results' is a testimonial. '48 hours to first lead, £100,000 project value booked within the first week' is a case study. Numbers create trust in a way that adjectives cannot. They signal specificity, which signals honesty. A claim that something was 'amazing' could mean anything. A claim that cost per lead dropped from £180 to £62 over 90 days means exactly one thing.
Use project values, timelines, conversion rates, lead volumes, or whatever metrics are relevant to your service and available to share. If the numbers are good, they will do more work than any copywriter.
How to structure case studies for SEO
A dedicated page for each case study, titled with the service and location, targets specific searches and creates indexable content that a testimonials page cannot. A page titled 'Luxury Villa Renovation, Marbella: Google Ads Campaign Results' is searchable. A paragraph on a testimonials page is not. Over time, a library of case study pages becomes a significant SEO asset.
How to get the numbers
Many business owners are reluctant to ask clients for result details. The simplest approach is to frame it as: 'Would you mind if I wrote up what we achieved together? I would love to be able to share it as an example of the work.' Most satisfied clients are pleased to be featured, and most will be happy to confirm the key numbers you already have on your side.
