Why Affiliate-Led Brands Are Winning on TikTok Shop UK
3 September 2026
TikTok has become the platform where challenger brands build a presence and take on the multinational conglomerates. For a lot of big, established brands, justifying a TikTok strategy is still a challenge, the platform doesn’t sit neatly inside a P&L, and it means giving up a fair bit of control over the narrative. That’s largely where the challengers have won: less red tape, and a much more direct route to an audience that’s paying attention.
When I dug into the category-level data behind that shift, one number stood out above everything else: across the top 50 categories on TikTok Shop UK, 72p in every £1 of revenue runs through affiliates – creators promoting products in their own voice, rather than a brand pushing an ad. Brands doing their own promotion (their own lives, their own shop content) only account for 12%, with the rest running through TikTok’s Shopping Mall.
That split isn’t neutral, it’s doing a lot of the work behind which categories are growing and which are stuck. The categories where affiliate revenue dominates, and where a handful of sellers have pulled well clear of everyone else, are the fastest-growing on the platform. Vacuums & Floor Care is a good example: 70% of its revenue sits with the top 3 sellers, it’s grown 74% year on year, and 87% of that revenue is affiliate driven. Skin Care Kits and the appliance categories (Household, Home and Kitchen) tell the same story, all sitting at 85-88% affiliate revenue and growing anywhere from 29% to 54%. Then we see the exact opposite in the likes of Collectibles which runs 66% self-promotion and only 6% affiliate, and it’s crawling along at 4.6% growth. Food & Beverages and Snacks look similar, both leaning heavily on self-promotion, both roughly flat or slightly down.
Womenswear & Underwear is the one that stops this being too neat, though. 68% of its revenue is affiliate-driven, which should put it in the fast-growing bucket, but it’s up just 0.8%. The difference is concentration: over 12,500 shops are splitting this category, and the top 3 sellers only hold 9% of it. So affiliate-heavy on its own isn’t the whole answer, it needs to be paired with a market that isn’t hopelessly fragmented.
I think what’s going on here is much simpler. Affiliate content works best when a creator can point at something specific and show it working – a vacuum picking up more dirt, a serum doing something visible to skin, an ingredient doing what it says on the tin. That lines up with something I’ve noticed across client work for a while now. Consumers are far more educated on products than they used to be, and I’d give TikTok a lot of the credit for that. I’ve seen first-hand the drop-off in people searching for generic “anti-ageing” or “anti-wrinkle” products – now they’re searching by ingredient such as Hyaluronic Acid, Salicylic Acid or Retinol, just to name a few. You see the same thing with food, where influencers are pointing out what’s overly processed to the despair of many, or comparing a budget dupe of a premium hair tool against the real thing on results rather than the name on the box. When a creator can demonstrate something rather than just claim it, people trust that over a polished ad, and I suspect that’s a big part of why the affiliate-heavy categories are pulling ahead the way they are.
Medicube’s a good example of a brand that’s built its growth on exactly this over the past year. It’s a challenger skincare brand, and rather than pouring money into traditional advertising, it leaned on its Korean skincare heritage and its ingredient story and let influencers do the demonstrating. The brand supplied the story and the creators validated it.
None of this means brands should drop self-promotion altogether. But the data’s clear: on TikTok Shop, growth is going to the categories where a handful of sellers have built proper affiliate distribution around a product that’s easy to demonstrate, not to the ones with the biggest ad spend. The brands doing well here are the ones treating affiliate strategy as a proper part of the plan, working out which products and which influencers actually make sense together, rather than bolting it on and hoping – even if, in the end, a chunk of that demand converts somewhere else entirely whether that’s Amazon, a retail channel or on a DTC website.
