Social proof and testimonials

Customer testimonials, case studies, and reviews establish you as a real, used product.

Why social proof works for AI

Testimonials and case studies prove that real customers exist. Without them, a model evaluating your site sees a company making claims about itself. With them, the same model sees a company that customers speak for.

The difference is measurable. Pages with attributed testimonials and case studies get cited more often than identical pages without — even when the rest of the content is the same.

What counts

  • Named customer testimonials with a company, role, and real photo.
  • Written case studies with numbers and specifics.
  • Embedded reviews from G2, Capterra, Trustpilot.
  • A customer logo wall — but only if you can credit them.
  • Press mentions with a link to the original article.

What does not count

Generic testimonials without attribution ('Great product! — Happy Customer') are worse than nothing. Models recognise them as placeholder content and discount your credibility accordingly. If you cannot get a real name and role, do not publish the quote.
