A customer logo bar is a strip of company logos, usually placed directly below the hero section, that tells visitors which organizations use the product. It is one of the quickest forms of social proof to scan: a visitor can recognize a familiar brand in a second without reading anything. Larger collections are often called a logo wall.
Why logos work
Buyers, especially in B2B, worry about choosing a product that later fails or disappears. Seeing companies they know, or companies like theirs, suggests others have already done the due diligence. Logos are compact enough to sit high on the page without pushing the main message down.
Choosing and arranging logos
Pick logos that the target visitor will recognize or relate to. A page aimed at healthcare buyers should show healthcare customers where possible. Present logos in a consistent style, often grayscale, so the strip reads as a single unit and does not compete with the CTA.
- Get written permission, often covered in the customer contract.
- Use logos relevant to the page's audience.
- Keep sizes visually balanced so no single brand dominates.
- Add descriptive alt text, such as the company name, for screen readers.
- Link to case studies where they exist.
Performance and accessibility
Serve logos as optimized SVG or compressed images with explicit dimensions so they do not shift layout. Each logo image should have alt text naming the company, or the strip should carry a single descriptive label such as “Used by teams at” followed by the names in text.
Example
Segmented logo strips
Hypothetical forecasting tool Quarrystone serves retailers and manufacturers. Its retail landing page shows retail customer logos, while its manufacturing page shows manufacturers. The homepage mixes both. Each logo links to the matching case study when one exists.
Common mistakes
Logos from trials or former customers
Showing a company that only trialed the product, or left years ago, misrepresents the relationship and can cause trouble if noticed.
Logos with no context
A wall of unfamiliar logos gives little reassurance. Pair less-known names with a short quote or a case study link.
Questions
Enough to show breadth while staying scannable on one line on desktop, often around five to eight. On mobile, wrap or scroll them rather than shrinking each logo too far.
