"We work with companies across every sector." That line does not build trust. What does is seeing, within the first few seconds, real client logos your visitor recognizes or perceives as credible.
In this article you will learn how to choose which logos to display, where to place them on your website, how to ask for permission, and which mistakes to avoid so the section turns visits into inquiries.
What client logos add to your website
Logos work as visual social proof: the brain reads "if these companies trust them, maybe I can too." They do not replace testimonials or case studies, but they reduce friction before the visitor reads a long paragraph.
They are especially useful on B2B websites, agencies, consultancies, SaaS products, and professional services where visitors compare several options and need fast credibility signals.
Which logos to show (and which to avoid)
Before designing the section, define clear criteria:
- Real clients with a demonstrable relationship: only logos from delivered projects or active contracts. Never invent brands or use logos from companies you only spoke with once.
- Recognition for your audience: one well-known logo in your sector beats ten generic brands nobody identifies.
- Variety of sectors or company sizes: if your ideal client is an SMB, mix mid-market logos with one stronger reference to anchor quality.
- Written permission: ask before publishing. A short email is usually enough: explain where the logo will appear and for how long.
Avoid endless rows of pixelated logos, brands irrelevant to your target audience, or direct competitors of your ideal visitor (yes, it happens).
Where to place the logo section on your website
Placement matters as much as selection:
- Right below the hero: ideal on your homepage while the visitor has not yet read your value proposition.
- On service pages: logos tied to a specific service ("we have built websites for…") reinforce specialization.
- Before the contact form: at moments of doubt, a visual trust bar can push visitors to submit.
- On landing pages: if you buy traffic, logos reduce bounce on the first screen.
How to design a logo section that converts
Design should help scanning, not distract:
- Use grayscale or monochrome logos for consistency; color can appear on hover.
- Keep 6 to 12 logos visible on desktop; on mobile, use a slow carousel or two compact rows.
- Add a clear heading: "Companies that trust us" works better than a block with no context.
- Pair with a concrete number when you have one: "+120 projects delivered" next to logos strengthens the message.
Client logos and SEO: what helps and what does not
Logos do not rank on their own, but they improve indirect signals: lower bounce rate, more time on page, and higher trust toward your CTA. Use descriptive alt text on each image ("Logo of [client company]") and do not stuff hidden text with brand names.
If you link to a case study or the client's website, keep links natural and avoid empty pages created only for SEO.
Common mistakes when publishing client logos
- Showing logos without permission: besides legal risk, a takedown request forces removal and hurts credibility.
- Unreadable logos on mobile: test on a real smartphone; if they are not recognizable, reduce quantity or increase size.
- Outdated section: logos from clients ten years ago can send the opposite message.
- Replacing testimonials with logos: complement them with written social proof and cases with measurable results.
How to measure whether your logo section works
With web analytics, compare bounce rate and CTA clicks on pages with and without the section. In A/B tests, try different headings ("They trusted us" vs "Recent projects") and different numbers of visible logos.
In sales conversations, ask: "Did you see any brand on our website that felt familiar?" That qualitative answer often correlates with higher-intent inquiries.
FAQ: client logos on business websites
How many logos should I show? Between 6 and 12 on desktop. Fewer if you lack recognizable brands; more only if readability stays strong.
Can I use a client's logo without a formal assignment contract? Best practice is explicit permission. Many companies accept when use is informational and does not imply endorsement.
What if a client asks to remove their logo? Remove it within 24-48 hours and update sales decks or PDFs that include it.
Do logos replace testimonials? No. Logos open the door; testimonials and case studies close the sale.
