Customer Marketing
Logos vs Quotes vs Case Studies
All three are customer evidence. They serve different purposes. Here is when to use which.
Customer evidence comes in three forms. Logos prove credibility (the buyer recognizes a peer brand). Quotes prove value (the buyer hears a peer's voice). Case studies prove transformation (the buyer sees the journey). All three matter. Most B2B sites use them interchangeably, which dilutes the impact of all three.
The right placement: logos on the homepage hero (trust signal in the first 3 seconds), quotes throughout product pages (proof that the feature delivers value), case studies on a dedicated /customers section (deep evidence for buyers in late-stage evaluation). Each format earns the right to the next. A logo gets attention. A quote builds interest. A case study converts.
The ratio that works: 6-10 logos in any logo bar (more starts to look desperate, fewer looks weak), 1 quote per product feature on relevant pages, and 8-15 case studies organized by industry/size/use case. Refresh the logos quarterly. Refresh the quotes annually. Add 1-2 new case studies per quarter. The cumulative library compounds.
The case study format that wins: 1-page format with the customer's name and logo at the top, a 1-paragraph problem statement, a 1-paragraph solution description, 3-5 quantitative outcome bullets, and a customer quote at the bottom. PDF and on-site. No 4-page narratives. The buyer skims. Make the skim productive.
