This article is for you if you:
- Are considering starting TikTok advertising for your e-commerce brand
- Want to understand what it takes to succeed on TikTok
- Are looking for an agency with documented TikTok expertise
- Want to see concrete results from a Danish TikTok campaign
An official TikTok Success Story is a case that TikTok itself has selected and published on their global Business Center. It's not something you buy or apply for — it's a recognition TikTok gives to campaigns that demonstrate exceptional performance and can inspire other advertisers.
Having an official TikTok case study is a validation of expertise at the platform's highest level.
The Starting Point
Sistie is a Danish jewelry brand founded by Kamille Carolina Østergaard as a sister brand to Izabel Camille. The brand had never advertised on TikTok, but had an organic presence with 33K+ followers.
The Objective
- Introduce Sistie to TikTok advertising
- Drive website conversions and lead generation
- Build brand awareness among young Danish women (18–35)
- Make TikTok a scalable sales channel
Our Approach
We developed a full-funnel strategy with:
- Spark Ads with 200+ creators: Creator whitelisting performed significantly better than standard video ads. We collaborated with both large profiles (Victoria Flintholm, Signe Kragh, Xenia) and micro-influencers.
- Platform-native content: All content was designed specifically for TikTok — POV formats, wishlist content, UGC-style production and seasonal hooks.
- Systematic A/B testing: We tested creative formats, audience targeting, campaign structure and messaging to identify winners.
- Multi-format campaigns: Catalogue Ads, Smart+ Shopping, Lead Generation and Traffic Campaigns worked together in one coordinated effort.

Based on this case — and our experience as a TikTok Platinum Partner — the most important factors are:
1. Platform-native content
TikTok is not Facebook. Content must feel authentic, trend-driven and native to the platform. Polished product videos perform worse than UGC-style content.
2. Creator partnerships
Spark Ads with creator whitelisting significantly outperform standard ads. Invest in creators who resonate with your target audience.
3. Full-funnel approach
Isolated campaigns don't work. You need a coordinated effort from awareness to conversion.
4. Systematic testing
A/B test everything: creative formats, audiences, campaign structure, messaging. Let data drive decisions.
5. Peak period optimization
Black Week, Christmas and other peak periods require a dedicated strategy and budget allocation.
This official TikTok case study is part of our broader TikTok expertise:
- TikTok Platinum Partner — Maintained all quarters in 2025
- Official TikTok Case Study — One of ~3 in Denmark
- Full-funnel capabilities — From Spark Ads to Smart+ Shopping
- 200+ creator network — Access to both large profiles and micro-influencers
As part of our E-Commerce Operating System we integrate TikTok with Meta, Google, Email and CRO to create synergy across all channels.
1. How much should I spend on TikTok to see results?
It depends on your audience and goals, but we recommend a minimum of 30,000–50,000 DKK/mo. in ad spend to be able to test and optimize effectively.
2. Does TikTok work for all e-commerce brands?
TikTok performs particularly well for brands with visual products and an audience under 40. Fashion, beauty, accessories and lifestyle brands typically see strong results.
3. Do I need to produce a lot of content?
Yes, TikTok requires ongoing new content. We recommend creator partnerships and UGC production to maintain a constant flow of fresh material.
4. Can you help with TikTok Shop?
Yes, we work with both TikTok Ads and TikTok Shop integration for brands that want to sell directly on the platform.
5. How long does it take to see results?
Typically 4–8 weeks to collect enough data to identify winning combinations. After that we can begin scaling.
Summary
An official TikTok Success Story is a strong validation of performance marketing expertise.
The case with Sistie shows how TikTok — with the right strategy — can develop from an experimental channel into a central driver of growth and profit in e-commerce.
