TikTok vs. YouTube vs. Instagram: The three-way battle of influencer marketing platforms
In short: The winner in the three-way battle of platforms depends on your e-commerce goals. TikTok dominates in terms of engagement with 18% for creators with under 100k followers (1), YouTube impresses with sustainable trust and the highest ad reach (67 million Germans) (2), while Instagram scores as a visual all-rounder with Reels and shopping functions.
Current development: With Instagram Plus, story visibility is extended to 48 hours - you can read what this means for the performance of story placements in our guide to Instagram Plus in Influencer Marketing.
The complexity of platform choice in modern e-commerce
Choosing the right social media platforms will be crucial for e-commerce success and ROI in 2025. With a projected market volume of $32.55 billion (3), companies face a complex decision between TikTok, YouTube and Instagram.
As your data-driven partners at Ad Specialist, we shed light on this three-way battle of digital giants. We don't just analyze superficial video views, we focus on measurable business outcomes for your e-commerce business.
TikTok: The King of Reach and Engagement
The unbeatable strengths of TikTok
TikTok masters the engagement game like no other social media platform. Creators on TikTok achieve an incredible 18% engagement rates for accounts with fewer than 100,000 followers (1) - a value that significantly exceeds Instagram (5%) and YouTube (3.5%).
Current key figures for Germany:
24.2 million people use TikTok every month in Germany (4)
69% of brands use TikTok in their marketing campaigns (5)
Videos on TikTok receive more views on average than on other platforms
Particularly strong performance for e-commerce content through shopping integration
The app particularly shines with Generation Z, where over a quarter (27%) of all users actively interact with influencer content (6). With TikTok, ByteDance has created a platform that has revolutionized the start of viral content.
The Challenges of TikTok: 1 Million Views, but 0 Sales
TikTok is cheap, fast - and everyone says it's really happening. But what's the point if you have 1 million views and 0 sales? TikTok is perfect for awareness, organic, rapid growth, which is cost-effective, viral hits - but really difficult to control.
The harsh reality of TikTok:
You never know if you'll go viral - and even if you do, that doesn't mean it'll convert
For e-commerce, this means high reach, but rarely predictable sales
Back then, we had a few brands that we started with on TikTok – some viral videos, but hardly any measurable sales
Works for impulsive products (cosmetics, lifestyle, cheap gadgets)
Offers with higher margins that require explanation? Gets hard
In the end, TikTok is like playing the lottery: if it works, everyone celebrates it. But is this really how you want to spend your hard-earned marketing budget?
In addition, political uncertainty influences the platform: investments in TikTok marketing fell by 17.2% due to regulatory concerns (3).
TikTok as an awareness tool, not as a primary sales channel
Combination with other platforms for complete funnel
YouTube: The Master of Storytelling Depth
The Sustainable Strengths of YouTube: Where Trust Turns into Conversions
YouTube dominates in terms of advertising reach with over 67 million people in Germany (2) - but that's only half the story. The real advantage: On YouTube we often reach much higher quality target groups who spend much more time consuming content from creators and therefore have much higher engagement. YouTube creator communities are also much stronger - if someone introduces a product they stand for, people are much more likely to convert.
Why YouTube Leads in Conversions:
You get 2-5 minutes in one iteration for creative storytelling
The users are focused while watching TV or on the computer, not in “swipe mode”
Long-lasting videos generate traffic for years
64% of users are between 18 and 34 years old – a target group with purchasing power (7)
A concrete example from our agency practice: Upway makes refurbished e-bikes with an average order value of 2,500 euros. After a lot of testing, they implemented a mega campaign with one of the biggest creators on the platform – Simplicissimus – which sold almost 250 e-bikes in just a few weeks. With this AOV you are welcome to work out for yourself what that means.
TheAd SpecialistFramework for profitable YouTube campaigns: We have developed a framework that we follow and with which we can almost always run successful and profitable campaigns:
Creator to Brand Match: Precise analysis of whether the creator really fits the brand
Audience Match: True match between creator audience and target group
Perfect Storytelling: Creative and credible storytelling with call-to-actions
Performance-driven execution: Campaigns are truly performance-driven
Skipping just one of these elements can end up burning an extremely large amount of money. YouTube performs particularly well with products that require explanation because you can combine storytelling AND call-to-action.
The Disadvantages of YouTube
YouTube requires more video production effort and shows slower growth compared to TikTok. Sponsored posts typically start at $2,500 per post (8), which means higher campaign costs for companies.
Conversion optimization through strategic call-to-actions
Use YouTube Shorts as a supplement to the main channel
Brand safety aspects of creator partnerships
E-commerce integration through shopping ads
Twitch: The underestimated platform for products that require explanation
The Myth: “Twitch is too niche and not worth it”
Most e-commerce decision-makers reject Twitch straight away: too nerdy, too small, too special. But that is often the biggest mistake in thinking. Twitch is not a mass channel - but that's exactly what makes it strong.
The hidden strengths of Twitch
Why Twitch works:
Live time means real attention
Community that listens - doesn't scroll
Users are often older, more affluent and more loyal than many people think
Perfect for products that need to be explained
Authentic, unscripted product presentation possible
Case Study: MagicHolz on Twitch For example, we scaled with MagicHolz via Twitch. The community there was active, the engagement rate was brutally high - and we were able to generate six-figure monthly sales within just a few months. People on Twitch are often older, more affluent and more loyal than many people think.
Plus, things were so bad on Twitch: We had almost written off the channel for MagicHolz for the time being. Even months later, conversions were coming in, which subsequently made the channel extremely profitable for us when we compare it with Instagram or YouTube.
It is extremely important to understand how these platforms work, how many conversions come in and when, and what the storytelling needs to look like in advance. You can now find all kinds of target groups on Twitch. That means saying “Twitch isn’t my target audience” is completely the wrong approach.
This is not a creator dart game - this is an extremely structured process:
Precise creator analysis for product fit
Live formats for authentic product demonstrations
Community integration instead of pure advertising messages
Long-term partnerships instead of one-shot campaigns

Instagram: The visual all-rounder for e-commerce
Instagram remains the visual powerhouse among social media platforms: 57% of all brands prefer Instagram for their influencer campaigns (10). The platform offers the widest range of formats – from Reels to Stories to shopping posts.
Current performance data:
Instagram reaches 2 billion users worldwide (11)
Reels dominate the platform with 50% of total usage time (11)
34 million potential ad reach in Germany (2)
Integrated shopping features for direct eCommerce sales
Meta ecosystem enables cross-platform marketing with Facebook
The development of Instagram shows constant innovation: new features such as shopping tags in Reels and Stories make the platform the ideal channel for e-commerce companies.
The Weaknesses of Instagram: Convenient, but Not Profitable
The hard truth: Instagram is the most popular, but not the best, channel. Almost every D2C brand starts with Instagram – because everyone does it. But is this really the best channel or just the most convenient?
The Instagram reality in practice:
Although Instagram brings views and reach, very few customers see predictable and profitable results in acquiring new customers
Conversions are often really bad compared to other platforms
The target group now simply continues to swipe when it comes to advertising because they are completely annoyed by advertising due to paid ads in the story feed alongside influencer campaigns
Usage fell from 76% to 47% for brands (10)
Case from our agency practice: We had a D2C brand from the food sector: invested 12,000 euros on Instagram, booked 6 creators, all in the same month. Result: high story views, low CPM - but not a single scalable creator who even came close to achieving a profitable CAC. After switching to YouTube with the same investment, we managed to immediately get the CAC into profitable regions of 20-30 euros - with a new customer rate of almost 100%.
Another customer told us: "I tried influencer marketing. It doesn't work." What came out of the audit? He had blown 20,000 euros on Instagram alone - without a decent strategy, without a suitable creator briefing and without looking at the most important KPIs such as target group and verticals. When we started with the customer on YouTube and Twitch, we earned back three times the investment within three weeks - simply because we approached it in a structured manner.
Instagram is of course convenient because the conception is also much simpler. But if you want sustainable sales, you definitely need marketing channels you can rely on.
We ourselves have been A/B testing campaigns on Instagram and YouTube for years with the same budget. The result was always: YouTube has similar CPM structures, delivers double to triple the number of new customers and we sometimes achieve up to 90-100% new customer rates.
YouTube leads in terms of reach with 67 million vs. 34 million for Instagram in Germany (2). Users spend more time watching videos on YouTube, while Instagram shows higher engagement rates on posts.
Which pays better: YouTube, Instagram or TikTok?
The ROI varies depending on the industry and target group:
TikTok: Lowest cost per engagement (12), ideal for awareness Instagram: Best conversion rates for e-commerce through shopping features YouTube: Highest long-term ROI through sustainable content performance (9)
Which social media platform makes more money: YouTube or TikTok?
YouTube generates higher absolute revenues through established monetization, while TikTok is rapidly catching up through e-commerce integration and shopping features. ByteDance is investing heavily in creator economy and shopping functions.
The Ad Specialist Conclusion: The best channel is not the one with the most views
What we've learned from over thousands of campaigns
Instagram, TikTok, Twitch, YouTube – every platform has its place. But if you're on the wrong channel, even the best creator won't help you.
The hard truth from our agency practice: The best channel is not the one that works best for other brands or the channel with the most views - but really the one that reaches the right target group at the right moment and is also able to sell through strong communities and engagement.
Not a single strategy – but an intelligent combination
For many e-commerce brands this means:
Less Instagram hype: Convenient is not profitable More data-driven YouTube & Twitch marketing: Structured processes instead of creator darts TikTok as an awareness tool: Not as a primary sales channel Platform mix based on product type: Products that require explanation need different channels than lifestyle items
The MagicHolz case as a blueprint:YouTube & Twitch brought us 1 million euros in additional sales within six months with a CAC of less than 20 euros. This wasn't a stroke of luck, but structured 3-stage marketing: Context → Creator Match → Conversion Trigger.
Modern e-commerce success requires cross-platform strategies (13). The most successful companies use:
TikTok for viral awareness and community building
Instagram for shopping integration and visual branding
YouTube for lasting trust and SEO benefits

Frequently asked questions & answers about TikTok, YouTube and Instagram
TikTok dominates in terms of engagement - creators with under 100,000 followers achieve an 18 percent engagement rate, far higher than Instagram (5 percent) or YouTube (3.5 percent). YouTube, on the other hand, impresses with its depth of storytelling and long-tail effect: videos continue to work for months and are found via Google. Instagram is the visual all-rounder with strong reach among Gen Z and Millennials, but weaker conversion than YouTube for products that require explanation.
That depends on your goal. TikTok offers more engagement and organic reach - especially for impulsive, affordable products like cosmetics or lifestyle gadgets. Instagram, on the other hand, has stronger shopping integration and is better suited for brand storytelling with a predictable result. But if you only look at the reach, you lose sight of the ROI. 1 million TikTok views with zero sales are worth less than 20,000 YouTube views with 40 new customers.
That depends on the product. YouTube works best for products that require explanation or higher prices, because creators have time for real storytelling and the community is highly engaged. Instagram is suitable for visual branding and quick reach, TikTok for awareness among young target groups. Twitch is often underestimated: With a 5 percent conversion rate for live viewers, the channel significantly outperforms Instagram and YouTube in the right niche. Our influencer marketing guide shows you how to turn your channel selection into an overall strategy.
Both formats are designed for reach and discovery, but with different strengths. Instagram Reels benefit from the existing community and shopping integration on a platform that many brands already trust. YouTube Shorts, on the other hand, benefit from Google's search engine power and can be indexed for a longer period of time. Which format performs better depends on where your target group is active and whether you are aiming for awareness or conversion.
Yes - and one of them is massively underestimated: Twitch. For gaming, tech and niche products that require explanation, Twitch delivers an impressive 5 percent conversion rate for live viewers and community loyalty, which other platforms can hardly achieve. Podcasts are another strong alternative, especially in the B2B and premium segments. LinkedIn is increasingly developing into an influencer platform for B2B brands where thought leadership and purchasing decisions are closely linked.
