How Thorne Drove a 38% Conversion Lift with Creator-Led Media on YouTube

Summary:

Creator-led content is behind some of the highest-performing conversion ads. According to Google, Partnership Ads that run from a creator's own channel drive up to 20% higher conversion rates than brand-led advertising.

Thorne saw the opportunity and partnered with TRIBE to put creators and YouTube Shorts to the test. We worked with seven wellness creators to craft content for Partnership Ads that ran head-to-head against their existing Demand Gen creative.

The Objective:

Thorne’s goal was simple: acquire new customers through paid YouTube Shorts ads during one of the most competitive and expensive periods of the advertising calendar, while testing if creator-led content could outperform their existing YouTube ads.

The Solution: 

To bring the brief to life, TRIBE identified and briefed wellness and lifestyle creators with over 10,000 subscribers whose voices could make premium supplements feel like a genuine part of everyday life.

The brief was direct but deliberately open: be yourself, keep it conversational, and show the product the way you actually use it, captured in natural light, real moments, and everyday routines. TRIBE managed the creative process end-to-end, from briefing through to feedback and final delivery. Seven Shorts were activated as YouTube Partnership Ads across December and January, giving Thorne a direct comparison between creator and brand-led content, while optimising for new customer conversions.

The Content: 

From get-ready-with-me's to balancing the extra demands of the holiday season, the content focused on the tried-and-tested benefits of Thorne's supplements, meeting audiences at a moment when self-care is easy to deprioritise and harder to ignore.

@healthyemmie took an expertise-led approach, breaking down the science behind Thorne's creatine and ashwaganda in a way that felt genuinely informative rather than promotional. Her content clearly resonated beyond paid, racking up almost 4 million organic views.

@itsevetteerenee made it personal, weaving Thorne into her holiday survival routine; moving her body, staying on top of nutrition, and protecting her self-care when it matters most.

@quenchyouradventure kept it real, showing how he navigates busy family life with a second baby on the way and why that means taking care of yourself first.

The Results: 

Across the 60-day campaign window, the TRIBE creator content did some serious work, delivering over 16.6M impressions, 296.8k clicks, and 13,812 conversions. Performance held strong against Thorne’s brand-led content, with a +12% higher CTR (1.78%), 21% lower CPC, =11% lower CPM and a massive +38% higher conversion rate.

Head-to-head against Thorne’s brand-led YouTube ads, the creator’s Shorts won at every stage of the funnel. Impressions and clicks were cheaper, and most importantly, more of those clicks turned into customers. With a 24% new customer ratio, Thorne’s objective to acquire new customers was a success. 

The added benefit of YouTube Partnership Ads? The opportunity to gain organic results. Without a single paid media dollar spent, the seven Shorts gained almost 10 million views and 38,000 engagements. 

Key takeaway

YouTube has built one of the most powerful performance ecosystems in paid media, and creators and Shorts are at the centre of it. The Thorne campaign shows what happens when you meet it with the right creative.

Creator-led Shorts outperformed brand-led ads at every stage of the funnel, and when the paid campaign ended, the content kept working organically with no additional spend.

The opportunity for brands is clear. Fueling YouTube Shorts advertising with creators isn’t a brand awareness play. It’s a full-funnel performance strategy.
