CHINA SPOTLIGHT: Douyin’s Double-Edged Sword by Kelly Zheng
A deep dive into one of the most powerful growth engines in China by Kelly Zheng.
Douyin is one of the most powerful growth engines in China. It has compressed the traditional funnel into a single environment, combining discovery, persuasion and purchase in one continuous experience. It reaches audiences at scale, converts them quickly, and, in many cases, introduces entirely new customers who do not exist within traditional e-commerce ecosystems.
For many brands in China, it has delivered exactly what they needed at the right moment: rapid, measurable growth. And yet, for a growing number of those same brands, something has begun to change. Growth slows, efficiency declines, investment continues to rise, but the incremental return begins to flatten. Not suddenly or dramatically, but persistently enough to raise the question:
What if the platform that accelerated your growth is also limiting it?
The mechanics of early success
Douyin’s strength lies in its ability to generate demand rather than simply capture it. Unlike traditional marketplaces such as T-mall or JD, where consumers arrive with a degree of intent, Douyin operates upstream. It creates interest through content, often before the consumer has actively entered the category. This makes it particularly effective for customer acquisition.
The data reflects this clearly. Douyin now accounts for approximately 18% of China’s total e-commerce market, and brands entering the platform typically experience a strong uplift in sales during the first one to three years.
This early phase can feel transformative as new audiences are reached, sales grow quickly and performance media appears highly efficient. From a planning perspective, it is easy to extrapolate this trajectory forward…which is exactly where the risk creeps in.
The plateau effect
Over time, the dynamics on Douyin shift. As brands increase spend, particularly in performance media, they move beyond the point of optimal investment. Additional budget continues to drive sales but at a diminishing rate, which means efficiency declines, even as absolute spend rises.
According to our China client data, around 80% of brands’ investment in Douyin performance media has already passed the optimal spend level . At the same time, the spend-to-sales ratio on Douyin performance media is typically between 1.0x and 3.5x higher than on T-mall .
These are not marginal differences, they point to a structural shift in efficiency. The pattern is consistent; initial growth followed by a gradual plateau, often beginning around year three. And yet, despite this, investment rarely declines.
The “new battlefield” effect
One of the more revealing dynamics is behavioural rather than technical. Many brands recognise that they are overspending on Douyin performance media. The data is often visible internally and the diminishing returns are understood but reducing investment feels risky. Why? Because Douyin is perceived as the new competitive battleground. Visibility within the platform is tied directly to spend. In at least one case I personally know of, when a brand switched off all Douyin media, sales on the platform dropped to zero!
This is the defining characteristic of a pay-to-play environment. It creates a feedback loop where continued investment is required to maintain performance, even as efficiency declines.
A full-funnel platform, misused
What makes this dynamic more complex is that Douyin is not simply a performance channel. It is one of the few platforms that genuinely operates across the full funnel. It can build awareness, shape consideration and drive conversion within the same ecosystem.
It also delivers unusually strong halo effects. Investment on Douyin, both in awareness and performance, has been shown to drive sales on T-mall, JD and even offline channels. This is not typical of most e-commerce platforms, which tend to capture demand rather than create it. The issue, therefore, is not the platform itself. It is how it is being used.
Many brands approach Douyin primarily as a performance channel, optimising for immediate conversion. In doing so, they underinvest in the very elements that sustain long-term efficiency: brand building, creative consistency and broader demand generation. The result is predictable; performance peaks early, then becomes increasingly expensive to maintain.
The ROI of Douyin performance media is, on average, 25% higher when awareness investment is at least half of performance spend .
Rebalancing the investment mix
The data points towards a different approach. When brands allocate a more balanced mix between awareness and performance within Douyin, outcomes improve materially. Our own data shows that the ROI of Douyin performance media is, on average, 25% higher when awareness investment is at least half of performance spend.
This reflects a broader principle seen across markets: brand investment enhances the effectiveness of performance activity. In Douyin’s case, this effect is amplified by the platform’s content-driven nature. Strong creative and consistent brand presence improve engagement, increase conversion efficiency, and extend impact beyond the platform itself.
From optimisation to calibration
For marketers, the implication is clear; Douyin should not be treated as a channel to maximise, but as an environment to calibrate. This requires moving beyond linear optimisation, where spend is increased as long as returns appear positive, towards a more deliberate approach based on scenario planning.
What happens to total business performance if Douyin performance spend is reduced by 15% and reallocated to brand-building activity?
How does the balance between Douyin, T-mall and offline channels affect overall growth?
At what point does additional Douyin investment begin to cannibalise returns elsewhere?
These questions are the essence of of incrementality and cannot be answered through platform metrics alone. They require a holistic view of performance, incorporating cross-channel effects, diminishing returns and long-term brand impact.
A more measured approach to growth
The implication is not that brands should reduce their presence on Douyin, but that they should treat it with greater precision. This means understanding where investment is genuinely incremental, where it is sustaining existing demand, and how activity on the platform is influencing performance across the wider ecosystem.
The commercial risk is rarely that Douyin ceases to deliver, but that it continues to deliver at a lower level of efficiency while consuming a disproportionate share of budget that could be working harder elsewhere.
