Wortspiel is a strategic marketing agency in Zürich, Switzerland. We help companies to win more customers faster with consulting, digital advertising and conversion optimization.

We don’t aim to become the largest agency, but rather the best. That’s why we rely on an experienced team and clear values.

So far we had the privilege of working with WordPress, Swisscom and American Express, among others. Maybe soon with you too:

Top performance is only possible with a high degree of specialisation. Therefore, we intentionally only offer the following three services. For everything else, we rely on strong partners.


As an agency we have insight into many companies. There we see which strategies work for which business models – and which do not. You are welcome to benefit from these insights. Together we analyze and optimize your company (vision, mission, values, goals), your offering (products, value proposition) and your marketing ( objectives, metrics, channels).

Digital Advertising

We help to increase the revenue and profit of your campaigns – on Google, YouTube and Bing. We are happy to over the complete management. Or we support you in improving your in-house know-how with audits, workshops, coaching and mentoring.

Conversion Optimization (CRO)

The more website visitors we convert into paying customers, the higher the return of Google Ads - and of all other advertising measures. We analyze your website, develop improvement hypotheses and test them for statistical relevance with Google Optimize.


In the video series Wortspiel.TV we celebrate what our clients have achieved with our help.

In the first episode we spoke with Wortspiel customer Laurent Decrue, co-founder and CEO of the largest Swiss relocation startup, MOVU.

Laurent explained how MOVU had become a market leader within a short period of time; how much of this success could be attributed to our Google Ads expertise and why he loves to ski.

Our values

While both the market and our offer will continue to evolve, our values will remain the same:

Wortspiel Values


Cooperation can only work well if we’re aligned on a personal level. We value honesty, humility and authenticity.


Trust is more important to us than contracts. As long as both parties are happy and continue to evolve together, we will keep working together. If this changes we will part ways.


The marketing landscape is changing so fast that long-term top performance is only possible with a high degree of specialisation. We prefer to do less and do it as well as possible.
