Content Agency

Strategy beats chance: we plan before the camera rolls. From concept and in-house production to motion graphics and sound — all from a single source, measurably optimised for reach and engagement.

Advertising Agency

Performance marketing is a craft. We build systems that turn strangers into paying customers — from Meta, Google and TikTok Ads to outdoor advertising. The result: a typical ROAS between 4 and 12.

Online × Offline

We manage events that stay memorable. Whether a global trade fair stand, a roadshow or a live sports event: our boxing event sold out in record time and had more media presence than any show since Max Schmeling.

Our DNA

Three levers. One goal: growth.

#1 Cross-Media Dominance

Real brands show up everywhere. We combine the viral power of TikTok, Instagram and YouTube with the massive reach of TV spots, streaming ads and outdoor advertising (OOH). On-site too, as your trade fair agency for the perfect brand presence.

Cross-Media →

#2 Content Creation: UGC & Viral

Classic advertising gets skipped — authentic content gets consumed. We produce user-generated content and high-end assets that build trust, tell the brand story and directly drive sales in your store.

UGC Agency →

#3 Performance at Sales Level

Reach is good, ROI is better. We dominate Google Ads, Google Display Ads and Amazon Ads. High-converting sales funnels, smart newsletter and email marketing build long-term customer loyalty. Also for your social recruiting.

Frequently Asked Questions

Advertising agency, outdoor advertising & performance at a glance.

What makes a modern full-service advertising agency?

A modern full-service advertising agency combines offline and online channels from a single source: from outdoor advertising (OOH/DOOH) to social media and content creation to data-driven performance marketing — with a team that thinks strategy, creative and media buying at the same time.

How do you effectively combine outdoor advertising (DOOH) with performance marketing?

Outdoor advertising creates broad brand awareness in public spaces, while performance marketing converts the resulting search and demand directly into clicks, leads and sales. We plan both channels cross-media and measure the interaction via brand-search uplift and attribution.

Which budgets and company sizes does Social Media One work with?

We work with international corporate brands such as Mercedes-Benz, DAZN and Toyota as well as growing mid-sized companies and startups — with scalable campaigns from the first social ads campaign to a nationwide outdoor advertising push.

What role does content creation play in the media mix?

Content is the raw material for every channel: the same UGC and high-end assets power social ads, outdoor advertising, streaming ads and the online shop. We produce in-house and through our 200+ creator network, so every campaign has enough material for all touchpoints.
