Latest / Social Media Marketing with Fexingo: Instagram, TikTok, LinkedIn, and Platform Strategy / Why Brands Are Using Private Instagram and TikTok Groups
Transcript
- Lucas: You know how every brand spent the last five years chasing the algorithm, trying to get their Reels in front of as many eyeballs as possible? Luna: Right. The whole 'go viral or go home' mentality. Lucas: Yeah. Well, there's a growing counter-movement, and it's actually pretty counterintuitive. Brands are starting to pull their content out of the public feed entirely. They're building private, invite-only groups within Instagram and TikTok. Luna: Private groups? You mean like Facebook Groups, but on the newer platforms? Lucas: Exactly. Instagram launched Broadcast Channels last year — they're basically one-way announcement channels that followers can join. And TikTok has Group Chats, which are more conversational. But the strategy is bigger than the feature. Brands aren't just sending push notifications — they're treating these spaces as exclusive clubs. Luna: So instead of shouting into the void of the For You Page, they're whispering to a curated room. What's the evidence that it works? Lucas: Let's start with Sephora. They have a private Instagram Broadcast Channel called 'Beauty Insider Circle.' It's invite-only for their top-tier loyalty members. In that channel, they post early access to new products, exclusive tutorials from their top creators, and they ask for direct feedback on upcoming launches. Luna: And the engagement numbers? Lucas: Sephora says their Broadcast Channel sees a click-through rate of about 14 percent — versus maybe 2 or 3 percent on a typical Instagram Story. That's massive. And the sentiment is overwhelmingly positive because members feel like insiders. Luna: Makes sense. When you're invited, you feel special. But isn't there a risk of alienating everyone else? The non-members? Lucas: That's the trade-off. You're trading reach for depth. But the argument is that a deeply engaged 10,000-person community is worth more than a loosely engaged 100,000-person follower base. Especially if you're a brand with a high customer lifetime value. Luna: So who else is doing this besides Sephora? Lucas: Nike is a big one. Their 'Nike Member' TikTok Group Chat is invite-only — you have to have made a purchase in the last 90 days and follow their main account. Inside, they share limited-edition drops, training tips from Nike trainers, and they even crowdsource ideas for new sneaker colorways. Luna: So they're literally using the group as a focus group. That's smart — you get real-time product feedback from your most loyal customers. Lucas: Exactly. And it's not just retail. We're seeing it in media, too. The Athletic, the sports journalism site, has a private Instagram Broadcast Channel for subscribers. They post breaking news an hour before it hits the public feed. Their retention among channel members is something like 90 percent after six months. Luna: That retention stat is wild. But I have to ask — doesn't this fragment the audience? I mean, if every brand starts doing this, the public feed becomes a ghost town of reposted content, and all the real value is locked inside these private rooms. Lucas: That's the fear. And I think it's a legitimate concern. But from a brand's perspective, the public feed is already getting more crowded and less organic. The algorithm is pushing paid content. So retreating to a private space where you control the experience is a rational response. Luna: Yeah, I can see that. Let's talk about the downsides though. What happens when a brand has a bad week — a product recall, a PR crisis — inside a private group? That group could become a breeding ground for negativity. Lucas: That's a really good point. You lose the ability to manage the narrative publicly. If a hundred angry superfans are venting in a private chat, you can't just delete comments like you can on a public post. You have to engage directly. Some brands are actually hiring community managers specifically for these channels. Luna: So the cost goes up. You need dedicated staff to moderate and nurture these groups. That's not a small investment. Lucas: Right. But for brands with high margins — like luxury, beauty, premium apparel — the ROI can justify it. Lululemon has a private Instagram Broadcast Channel for their 'Sweat Collective' — fitness instructors and trainers. They don't just post content; they host weekly live Q&As with their designers. The feedback loop is incredible. Luna: I want to zoom out for a second. Is this a TikTok and Instagram thing, or are we seeing it on other platforms too? Lucas: You're seeing early versions on LinkedIn — they have 'LinkedIn Groups' obviously, but those are mostly public or open. The private, invite-only newsletters are actually the closest parallel on LinkedIn. Some creators are gating their best content behind a paid newsletter subscription. Same psychology, different format. Luna: So the unifying principle is exclusivity. You get access because you've proven loyalty. That's a big shift from the 'everyone is welcome' ethos of early social media. Lucas: It really is. And I think it's a response to the algorithmic fatigue we've been talking about for the last couple of years. Users are tired of being sold to in their feed. But they're okay with being sold to in a private channel where they opted in and where the content actually feels curated for them. Luna: Before we go further — you know, if this episode is useful to you, and you want to keep the show ad-free, we do have a support page. It's buy me a coffee dot com slash fexingo. That's literally what funds these conversations — a handful of listeners who chip in. No pressure, just if you find value. Lucas: Yeah, it's a small ask that makes a big difference. So back to private groups — let's talk about what happens to the audience that's not in the club. Luna: Right. If you're a brand with a million followers but only 20,000 in your private channel, how do you keep the other 980,000 engaged? Lucas: That's the challenge. Most brands use the public feed as a funnel. They'll post teasers — 'Want early access to our summer collection? Join our Broadcast Channel.' So the public content becomes a recruitment tool. But if the best content is always behind the gate, the public feed starts to feel like a second-tier experience. Luna: Which could hurt your overall brand perception. You're basically telling your mass audience that they're not special enough. Lucas: Exactly. That's why some brands are experimenting with tiers. Sephora, for example, has three levels of their private channel. Level one is open to anyone who follows them — you get weekly tips. Level two requires a purchase — you get product previews. Level three is by invitation only — you get to co-create products with their team. Luna: So it's a ladder. You can climb your way to deeper access. That feels more inclusive while still rewarding loyalty. Lucas: Right. And it creates a clear incentive for customers to engage more. I think that tiered model is going to become the standard. Because the data is pretty clear — private channels drive 3 to 5 times higher engagement per post compared to the public feed. Luna: But engagement isn't the same as conversion. Do we know if these groups actually drive sales? Lucas: There's some early data. A case study from a direct to consumer skincare brand called 'The Ordinary' — they launched a private TikTok Group Chat for their top 500 customers. They shared a link to a new product two days before the public launch. The conversion rate in that group was 22 percent. Their typical email campaign conversion is about 4 percent. Luna: Twenty-two percent? That's insane. But it's a tiny sample — five hundred customers. Can you scale that? Lucas: That's the million-dollar question. Sephora has about 200,000 members across their Broadcast Channel tiers. Their overall conversion is lower, obviously — but still 8 percent, which is double their public feed conversion. So it does scale, but the intimacy drops as the group grows. Luna: So there's a natural ceiling. You can't have a 'private' group with a million members and expect the same vibe. Lucas: Exactly. And that's where the community management cost comes in. Most brands are finding that the sweet spot is somewhere between 5,000 and 50,000 members for a single channel. Beyond that, you need to subdivide by interest or region. Luna: That's a lot of overhead. But if the return is there, I guess it's worth it. What about the risk of platform dependency? If Instagram or TikTok changes the feature or kills it, you lose your community. Lucas: That's a huge risk. And both platforms have a history of deprecating features. Remember when Instagram killed the 'Following' tab? Or when TikTok experimented with 'Stories' and then dropped it? Brands are aware of this, so some are dual-posting — they run a private group on Instagram and a parallel one on their own website via a forum or a membership app. Luna: So the private group on the platform is a front door, but the actual community lives on owned channels. That's smart. Lucas: It is. And I think that's the direction we're heading — brands using social platforms as acquisition funnels for their own private communities. The platforms become the drawbridge, not the castle. Luna: I like that metaphor. So for a marketer listening right now — what's the first step? How do you decide if this strategy is right for your brand? Lucas: First, look at your customer lifetime value. If your average customer spends $50 once and never returns, a private group probably isn't worth the investment. But if you have repeat purchasers, subscription models, or high-ticket items — luxury goods, software, coaching — then absolutely test it. Start with a small group of your top 100 customers and see how they respond. Luna: And don't just broadcast. Actually talk to them. Ask questions. The magic is in the reciprocity. Lucas: Right. The brands that succeed are the ones that treat the group as a two-way conversation, not a one-way megaphone. Nike's group doesn't just announce drops — they ask members what colorways they want. Sephora asks for ingredient feedback. That's what builds genuine loyalty. Luna: Yeah, I think that's the real insight. It's not about gating content — it's about creating a feedback loop that makes customers feel heard. And that's something the public feed can't really do. Lucas: Exactly. The algorithm optimizes for engagement, but it doesn't optimize for relationship. Private groups are a relationship-first strategy. And as the public feed becomes more transactional, that's going to be the differentiator. Luna: So we might look back in a few years and see this as the moment social media marketing split into two tracks — mass broadcast and intimate community. Lucas: I think that's exactly what's happening. And for marketers, the question is: which track do you want to ride? Luna: Good place to leave it. Thanks, Lucas. Lucas: Thanks, Luna.
