How to add proof to your website when you have no case studies yet

Seven kinds of proof work without formal case studies: a named customer, a short quote, a specific number, a before and after, usage figures, third-party signals, and a worked example of your method. Proof is often missing. In Outfly's Growth Gaps 2026 sample, no case study, testimonial or client wording was found on 30 percent of 628 UK company websites.

Seven kinds of proof you probably already have

  1. A named customer. One name a buyer recognises, with permission, carries more weight than a paragraph of claims.
  2. A short quote. Two sentences from a real customer, with their name, role and company. Ask while the result is fresh.
  3. A specific number. Time saved, cost reduced, conversion improved. Say how it was measured and over what period.
  4. A before and after. What a customer did before, and what changed. It does not need to be long.
  5. Usage. Customers served, projects delivered, years trading, if they are true and you can back them up.
  6. Third-party signals. Awards, certifications, press mentions, investors, partners, each with a link where possible.
  7. Your method, shown. A worked example of how you approach a problem proves competence before you have results to publish.

Why it matters

A buyer who does not know you needs a reason to believe the claims on your page. Without proof, every claim reads as an opinion about yourself. With it, the same claim reads as something that happened.

In Outfly's Growth Gaps 2026 report, a keyword scan of 628 UK company websites found no wording about case studies, testimonials or clients on 30 percent of them (189 sites). Among UK startups the share was 40 percent (129 of 325). The full figures are in the report.

Where to put it

Put each piece of proof beside the claim it supports. The homepage headline, the pricing page and any page paid traffic lands on all need proof in the first screen. Write proof as text as well as logos, because a wall of logo images is harder for search engines and AI assistants to read, and some visitors skim straight past it.

Keep it checkable

Use only names and numbers you have permission for and can substantiate. A single result a buyer can check is worth more than several they cannot.

If visitors are arriving and leaving, start with this guide. If you are paying for traffic that does not convert, see paid costs more than it returns.
