Short testimonials outperform long ones

A real customer says: "Switched from Competitor. Saved 4 hours a week." That's credible. It's specific. It sounds like something a person would actually say.

A three-paragraph testimonial that covers the customer's background, their decision-making process, the implementation, and the results reads like marketing copy. Even if it's genuine, it sounds ghostwritten. Length creates suspicion.

Short testimonials work for the same reason short product reviews work. Real people communicate in short bursts. They don't write essays about software they use. "Works great, saved us time" is how actual humans talk. Polished paragraphs are how marketing teams write.

The format matters too. Name + company + one sentence is the template. Photo helps credibility. Logo helps authority. But the quote itself should be short enough to read in 3 seconds. If it takes longer than that, most visitors will skip it entirely and you lose the social proof you worked to collect.
