International strategy: One briefing, 16 markets
Every international campaign starts with a global briefing – and local implementation. We translate your brand positioning into platform content for every market. What converts in New York needs different hooks than what works in Paris or Stockholm.
The result is not a one-size-fits-all campaign, but a coordinated multi-market rollout: the same brand voice, market-adapted creative, standardized reporting. We have already implemented this simultaneously in several countries for Catrice, Wacom and Tesa.
Content Production: Europe & USA
We produce content remotely and on location in Europe and the USA. Photo & video, UGC, reels, TikToks, YouTube productions – all from a single source. What converts today: authentic video hooks, product in real context, no glossy ads that scroll away.
Platforms:
Community Management: Global brand voice
Community management in multiple languages and time zones requires structure and precision. We manage brand voice in English, German, French, Spanish and more – active daily, response times under 60 minutes. The algorithm rewards active profiles with organic reach that costs no additional advertising budget.
Influencer marketing: local creators, global impact
Every market has its key creators. We maintain personal relationships with top creators in London, Paris, New York, Los Angeles and more. Influencer marketing with us means real relationships – no cold booking via platforms.
For product launches, seeding campaigns or influencer events across Europe and the USA – we connect your brand with the right people in every market.
Reporting: One dashboard, all markets
Monthly international reporting – clear KPIs per market: reach, engagement, follower quality, cost-per-click, ROAS. All markets are compared with each other. What works is scaled. Used by Wacom, Tesa and Unicef – with demonstrable results.
International social ads: Meta, TikTok, YouTube
Social ads are the fastest way to build international reach and sell directly. Meta Ads (Instagram + Facebook), TikTok Ads, YouTube Ads – each platform has its own strengths, creative requirements and algorithm logic per market.
The difference to local advertising: international campaigns require market-specific creative, localized copy and regional target group segmentation. We take care of it all – from London to New York, from Paris to Los Angeles.
Cross-market campaign workflow
- Target definition: reach, leads, sales – per market and globally
- Audience setup: Custom audiences, lookalikes, geotargeting per city and region
- Creative production: video, static, carousel – market-adapted and A/B-tested
- Launch with close monitoring per market in the first 72 hours
- Cross-market optimization and budget reallocation based on performance data
What do international social media ads cost?
Advertising budgets and agency fees vary depending on the market, platform and target. What counts is not the price of the ad, but the ROAS achieved in each market. We calculate backwards together: What can a conversion cost so that the campaign is profitable internationally? Initial consultation: free of charge. Inquire now.
Full-Funnel International: From awareness to conversion
Social ads alone are not a complete international strategy. TikTok builds awareness in new markets, Instagram retargets interested parties – Google Ads completes the purchase decision. Performance marketing that thinks across channels and markets turns clicks into customers – worldwide.
