Your best customer review sitting on G2 is free attention you're not using. A prospect reads that quote, sees their own challenge reflected back at them, and moves one step closer to a demo request. But the moment you drop that review quote into a LinkedIn ad, a Google Search campaign, or an email, you've crossed into territory where FTC rules apply and platform permissions matter.
Most B2B SaaS teams skip the legal checks because compliance feels like friction. The risk feels remote until it isn't. The FTC has clarified that using customer testimonials in advertising requires written consent from the reviewer, and you cannot tie compensation to review sentiment. Violations carry civil penalties up to $53,088 each. A single campaign using unvetted quotes across multiple platforms could rack up expensive problems fast.
The good news: turning review quotes into compliant, high-converting ad creative is repeatable once you know the system. You need three things: a clear reading of what each platform allows, a documented consent process, and a content strategy that stretches each quote across multiple formats. This guide walks through all three.
What you can and cannot do with quotes from review platforms
G2, Capterra, and Trustpilot own the content reviewers post on their sites. You do not automatically own the right to reuse that quote in paid ads just because a customer wrote it about your product. Each platform has different rules, and they enforce them.
G2's terms allow you to reuse quotes in marketing materials if you link back to the original review on G2. That means your LinkedIn ad, landing page, or email can include the quote if you include a hyperlink to the full review. Capterra has similar rules but is stricter about product context. If you quote a reviewer who specifically praised your customer support, you cannot move that quote to an ad emphasizing price. Trustpilot requires consent from the reviewer before you use their review outside the platform, period. No quote, no repurposing without asking first.
The practical move: treat platform terms as a baseline, not a ceiling. Even if a platform technically allows quote reuse, get explicit written consent from the customer who wrote the review. A quick email asking permission eliminates ambiguity and protects you against future policy changes. Most customers say yes. Those who say no are doing you a favor, because their hesitation usually signals a review that might not perform well in ads anyway.
The consent conversation that actually works
Your review request process can bake consent in from day one. When you email a customer asking them to leave a review on G2, add a second ask: 'If your review is positive, we may want to use a quote in our marketing. Can we have permission to do that?' Most customers will agree in that moment, and you have documented consent before the review goes live.
If you are working backward through existing reviews, a direct message works better than a template email. Something like, 'We came across your review on G2 and loved your point about how our reporting saved your team time. We'd like to use that quote in a LinkedIn campaign. Do we have your permission?' Personal and specific beats generic. Expect a 70 to 80 percent yes rate if the review is genuinely positive and recent.
Document the consent. A Slack message, an email reply, or a form submission all work. You just need proof that you asked and the person said yes. If you run ads using quotes and ever get a question from the FTC or a platform, that consent record is your defense.
Format matters more than you think for both compliance and conversion
A single customer quote can fuel multiple ad formats, and the format shapes both the legal exposure and the click-through rate. A static image ad on LinkedIn with a quote overlay is straightforward. A short-form video testimonial where the customer actually speaks the quote is more powerful but requires additional consent because you are now using their likeness. An email snippet using the quote is low risk and often outperforms paid ads for cost per qualified lead.
Here is the pattern that works: start with the simplest format that makes sense for your channel. A quote-card LinkedIn ad works fast and converts well for awareness campaigns. If the customer approves, layer in a video testimonial for retargeting and cold outreach. Repurpose that same quote in your sales enablement emails. A single review quote can live in five or six places, each with a slightly different angle or audience. That stretches marketing ROI and gives reviewers the feeling that their feedback actually shapes how you present yourself to the market.
One practical detail: always include attribution. 'According to Sarah, VP of Ops at MediTech Inc.' or 'Sarah M., G2 reviewer' provides credibility and signals that this is a real customer, not a marketing fabrication. Attribution also makes the quote feel less like an ad and more like earned social proof, which tends to improve performance.
Picking quotes that convert means looking past the star rating
The five-star review with a one-sentence comment is nice for your rating average. It is usually useless in ads. Specificity converts. A prospect reading an ad is asking 'Is this for someone like me?' A quote that names a specific problem, a specific outcome, or a specific role answers that question. 'This tool cut our reporting time by 40 percent' performs better than 'Great product, highly recommend.'
If you are moving beyond intuition into data, review analysis tools can now scan hundreds of reviews to surface recurring themes, pain points, and sentiment patterns. You can identify which problems your customers mention most often, which outcomes they value, and which reviewer roles or industries mention specific benefits. That analysis lets you pick quotes strategically rather than randomly. You pull the quote about onboarding speed for campaigns aimed at IT directors and the quote about ease of use for campaigns aimed at individual contributors.
Match the quote to the campaign objective, the audience segment, and the stage in the buying cycle. A quote about ROI and financial impact lands differently than a quote about user adoption or integration ease. Treating review quotes as atomic assets that you plug into every campaign is the mistake that kills performance. Treating them as precise tools that you deploy where they fit is what builds qualified pipeline.
Building the repeatable workflow
Set up a simple workflow so quote collection and consent become automatic, not a project. When a new five-star or four-star review lands on G2 or Capterra, add it to a shared sheet. Note the customer name, the quote, the topic (support, pricing, implementation, whatever), and the platform it came from. Each week, have someone reach out to the best new reviews asking for consent to repurpose the quote. Most take five minutes.
Once you have consent, treat that quote like inventory. Tag it by topic, industry, and reviewer role. Build a simple library. When a campaign is about to launch, filter the library for relevant quotes. Pick three to five that match the audience and the message, and start designing ad creative. This removes the guessing. You are not hunting for inspiration. You are pulling from a validated set of assets.
The last step is tracking. When you run ads using review quotes, tag them so you can measure performance later. Do carousel ads with rotating customer quotes outperform static ads? Do video testimonials drive higher quality leads than image cards? Over time, you build intuition about which quote types, which topics, and which formats produce the best ROI. That feedback loop is what transforms review quotes from one-off marketing fuel into a repeatable demand generation engine.
