When a prospect is evaluating you, they rarely stop at your website. They open a second tab and look you up on LinkedIn — to see whether the company is real, active, and vouched for by people who are not you. That makes your LinkedIn company page a proof surface whether you treat it as one or not. A visitor arriving there finds either a living page with evidence that customers are happy, or a neglected shell that quietly undercuts the confidence your homepage just built. A testimonial belongs on that page, but the reasons it works there are different from the reasons it works on your site, and so is the way you should present it.
Why the LinkedIn context changes the job
On your own website, a testimonial is one element in a page you fully control, sitting near a headline and a call to action you designed. On LinkedIn, the same quote lands in an infinite scroll of other companies' updates, on a platform the prospect trusts more than your marketing precisely because you do not own it. That borrowed credibility is the whole advantage: a customer praising you on a third-party network reads as less staged than the identical words on your landing page. But it comes with a constraint — the feed is skimmed at speed, and a wall of text scrolls past unread. The quote has to earn a stop in the first line, which is a harder bar than a static testimonial section on your site ever has to clear.
Post it, don't just park it
The most common mistake is to treat the LinkedIn page as a filing cabinet — dropping a testimonial into the "About" section or a pinned graphic and considering the job done. The About section is read by almost no one; it is checked, not read. The place a testimonial actually earns impressions is the feed, published as a post, because that is what LinkedIn distributes. Turn the customer's words into a short update: lead with the outcome they described, attribute it clearly with their name and company, and let the platform push it to your followers and, if it earns engagement, beyond them. A testimonial parked in a profile field reaches the handful of people who go looking; the same testimonial posted reaches the audience LinkedIn decides to show it to, which is the point of being there at all.
Adapt the format to the feed
A testimonial that works on your website often needs trimming to work in the feed. A three-sentence quote that reads well beside a photo on a landing page is too dense to stop a thumb mid-scroll. Pull the single strongest line to the top so it survives the "see more" truncation, then let the rest follow for those who expand it. The same discipline that produces a good on-site pull quote applies here, and the tradeoffs are the subject of ProofShow's guidance on how many testimonials do you need on a landing page — a few sharp lines outperform a paragraph nobody finishes. If the endorsement started as a recorded clip, a short native video often outperforms text on LinkedIn, for reasons covered in video vs written testimonials.
Let the attribution do the vouching
The reason a LinkedIn testimonial can outperform the same words on your site is that the person quoted is a real, clickable profile on the same network. Lean into that. Tag the customer and their company when you have their permission, so a skeptical reader can click through and confirm the person exists, works where you say, and is not an invention. That verifiability is the credibility engine of the platform, and it is why a named, tagged endorsement on LinkedIn can carry more weight than an anonymous five-star quote on a landing page. Whether to include a face alongside the name — here as much as on your site — is the decision examined in should you put a photo with every testimonial. The more concretely the reader can locate the person, the harder the proof is to dismiss.
Get permission before you tag
Reposting a customer's private praise as a public LinkedIn update, with their name and employer attached, is a more exposed act than quoting them on your own site. Their name now appears on your marketing inside their own professional network, where their colleagues and their own prospects will see it. Ask first, and ask specifically: confirm they are comfortable being tagged, named, and associated with your company publicly on the platform. Most happy customers say yes, and many will engage with the post once it is live, which extends its reach further. But the permission has to be explicit, because a customer surprised to find themselves featured is a customer you have converted from an advocate into a complaint.
The honest answer
Yes — put a testimonial on your LinkedIn company page, but publish it as a post rather than burying it in a profile field, trim it to survive the feed, tag the named customer with their permission, and let the platform's borrowed credibility do the work your homepage cannot. Done that way, it reaches an audience you do not have to pay for and carries a verifiability your own site can never quite match. Done as a static line in the About section, it reaches almost no one and might as well not exist. The page is a proof surface prospects check whether you cultivate it or not; the only question is whether they find evidence there or an empty shell.
