Latest / Social Media Marketing with Fexingo: Instagram, TikTok, LinkedIn, and Platform Strategy / Why Brands Are Turning Social Comments Into Ad Campaigns
Transcript
- Lucas: You know that feeling when you scroll past an ad on Instagram and it just looks like an ad — polished, staged, forgettable? Now imagine scrolling and seeing an ad that looks like a screenshot of someone's comment. It stops you because it doesn't feel like an ad. Luna: I've definitely seen those. Brands turning their own comment sections into ads. Or even taking a random user's hot take and running it as a Facebook post. It feels almost too low-effort to work, but apparently it does. Lucas: It works well enough that it's becoming a deliberate strategy. A friend of mine runs social for a direct to consumer brand and she told me their best-performing ad last quarter was literally a screenshot of a five-star review from a stranger, turned into a static image ad on Instagram. Cost per click was about forty percent lower than their studio-produced video. Luna: Forty percent — that's huge. Is that because people trust a random person's comment more than a brand's own message? Classic social proof. Lucas: Exactly. And it's not just reviews. I've seen brands take negative comments too — not to shame the commenter, but to lean into the honesty. One outdoor gear company ran an ad that was just a comment saying 'I returned this tent because it was too heavy to backpack with.' And the brand's reply underneath: 'Fair point. Here's our ultralight model.' That ad apparently had a click-through rate triple their average. Luna: So they're using criticism as a hook. That's smart because it signals confidence. If a brand is willing to show a negative comment, they seem more trustworthy. Lucas: Right. And the format itself is cheap to produce. You're not hiring a creative agency. You're not shooting a commercial. You're just screenshotting a comment, maybe adding a simple call to action overlay, and launching it as an ad. The barrier to testing is almost zero. Luna: But isn't there a legal gray area? If someone writes a comment on your brand's post, do you have the right to use it in a paid ad? I feel like that's murky. Lucas: It is murky. Most platform terms of service say that by posting, you grant the platform a license to use your content. But that license isn't automatically extended to the brand for paid advertising. I've talked to a couple of lawyers about this, and their advice is: always ask permission before using a user's comment in a paid placement. A simple DM can cover you. Some brands even offer a small product credit or a gift card as a thank you. Luna: That seems fair. And it probably makes the commenter feel special — like they're part of the brand story. I bet they even share the ad with their friends, creating more organic reach. Lucas: Exactly. It becomes a virtuous cycle. And it's not just text comments. I've seen brands repurpose TikTok comments as video ads — someone says something funny, and the brand stitches it into a response video, then boosts that response as a Spark Ad. Duolingo does this really well. Their social team is constantly pulling comments from their own videos and turning them into new content. Luna: Duolingo's social voice is already so playful. They can get away with things that a more formal brand couldn't. But what about B2B? Can a software company pull this off? Luna: It's a different tone, but the principle still applies. I've seen a CRM company run LinkedIn ads that are just a screenshot of a customer's LinkedIn comment saying 'This tool saved our sales team 10 hours a week.' That's incredibly specific and credible. No marketing copy needed. Lucas: And LinkedIn's ad platform actually rewards that kind of authenticity because the algorithm favors high engagement. A comment-based ad tends to get more comments, which drives it further. It's a feedback loop. Luna: So the key is selecting the right comment. Not every comment is ad-worthy. What's the filter? Should it be funny, insightful, critical? How do brands decide? Lucas: From what I've seen, the best comments for ads have three qualities. First, they're specific — mentioning a feature, a benefit, or a real use case. 'Great product' is too vague. Second, they're conversational — they sound like a real person, not a bot. Third, they have emotional weight — enthusiasm, surprise, even mild frustration that the brand resolves. One retailer I know uses a simple scoring system: they rate comments on specificity, emotion, and originality on a 1-to-5 scale, and only use ones that score 12 or above. Luna: That's a really practical framework. And then they probably A/B test them against traditional ads to see if the lower cost per click holds true for their brand. Lucas: Exactly. And the data from a 2025 Meta internal study — which was shared at their marketing summit — showed that ads using user-generated comments had a thirty percent higher conversion rate on average compared to brand-created ads in the same campaigns. The study covered over five hundred advertisers across retail, travel, and finance. Luna: That's a solid sample size. But I wonder if there's a diminishing returns effect. If every brand starts doing this, will people eventually get desensitized to the 'screenshot of a comment' format? Lucas: Possibly. But I think the format is less important than the authenticity. The principle is: real people saying real things about your product. Even if the screenshot format becomes cliché, the underlying truth — that user voices are more persuasive than brand voices — isn't going away. Brands that can consistently surface and amplify genuine customer sentiment will always have an edge. Luna: So it's more of a mindset shift than a tactic. Instead of thinking 'what should I say in my ad?' the question becomes 'what are my customers already saying that I can amplify?' Lucas: That's a great way to put it. And honestly, if these marketing conversations have sparked something you've actually used in your own work, that's the whole point of the show. Luna: Yeah, totally. A couple of dollars a month is genuinely what keeps these going — buy me a coffee dot com slash fexingo, if you've gotten something out of them. Lucas: And we really mean that. It's a small thing, but it makes a big difference in keeping this ad-free and focused on the actual ideas. Luna: Absolutely. Alright, so back to comments as ads — one thing I've noticed is that some brands are even running ads that are just screenshots of their own replies to comments. So the comment itself is from the brand, but it's in response to a customer question. That feels like a whole different layer. Lucas: That's a smart twist. It's like showing your customer service in action. I saw a luggage brand do this: a customer commented 'Do these suitcases survive being thrown by airport baggage handlers?' and the brand replied with a photo of a suitcase being run over by a forklift. They turned that entire exchange into an ad. It was hilarious and convincing. Luna: That's brilliant because it proves durability without a scripted demo. It's almost like a mini-case study compressed into a comment thread. Lucas: Exactly. And the ROI on that type of creative is hard to beat. We're talking about a few minutes of work per ad versus days or weeks of production. For small businesses especially, this is a game changer. Luna: But I do want to caution against one thing: if you're a brand that doesn't have a lot of social engagement yet, you can't just start pulling comments out of thin air. You need to build that community first. Otherwise you're just screenshotting crickets. Lucas: That's a fair point. The strategy only works if you have an active, vocal audience. But even a brand with a small but passionate following can find gold in the comments. I've seen a micro-SaaS company with only two thousand Instagram followers run a comment-based ad that outperformed everything else they'd done. Their followers were just super engaged. Luna: So it's about depth over breadth. A hundred loyal fans commenting can be more valuable than ten thousand passive followers. Lucas: Right. And one more thing: the best time to start collecting comments for ads is when you launch a new product. That's when excitement is highest and people are posting their first impressions. If you can capture that wave and turn it into paid creative, you're riding momentum. Luna: I love that. It's like real-time marketing meets paid media. And it ties back to something we've said before on this show — the line between organic and paid is blurring more every year. Lucas: It really is. And comment-based ads are a perfect example of that blur. The ad itself is organic content, just boosted with a budget. So it doesn't feel like an interruption — it feels like a continuation of the conversation the audience is already having. Luna: That's the ideal state for any advertiser, isn't it? An ad that doesn't feel like an ad. Lucas: Exactly. And if you can get there by simply screenshotting what your customers are already saying, why wouldn't you?
