What customers say about Kontexter

Kontexter is our long-standing and reliable partner for search engine marketing. Without him, Save the Children Germany would not be where we are today. Mac Mueller is always on hand when we need him and is always ready with new ideas, lots of expertise and sound experience.

Kontexter understands how an NGO can use the opportunities of the Internet to achieve great impact. The combination of new ideas, great expertise and concrete recommendations for implementation is great.

With Kontexter, we have an expert at our side who continuously supports us in using our Google Ads budget effectively. We particularly appreciate his reliability and his initiative in trying out new things and at the same time optimizing the campaigns with a focus on performance. As a result, Mac Mueller has played an important role in effectively marketing Carlsen very heterogeneous program to our diverse target groups via Google Ads since 2014. We are all the more pleased that Kontexter has also been implementing this expertise for us with Amazon Ads since 2019.

Over the past year and a half I have worked very closely together with Mac and his agency Kontexter. As digital is not my background I really appreciate all the extra support I always receive outside of the ’normal‘ services Kontexter provides. Not only has this really helped me find my way a lot quicker in the digital world, it has also enabled me to not only optimise our campaigns but also ensure I spend budget where it most makes sense for the best possible results. What I also love is the great personal relationship we have developed during the course of our campaigns and working together, as well as knowing I can always count on Mac, even when a humanitarian emergency happens outside of working hours.

Kontexter successfully initiated our application process with Google in 2009 and has managed our Google Ad Grants account ever since. Thanks to this work, almost 30,000 additional Internet users come into contact with our NGO Reset every month.

Thanks to Kontexter’s excellent work, SAES has gained attention and relevance on the Internet. Kontexter’s targeted, reliable and effective work has enabled us to grow as a company, acquire new customers and expand product segments. As a medium-sized company, Kontexter’s really great work is our main marketing tool that we can no longer do without.

Thanks to the collaboration with Kontexter, we were able to introduce efficient and performance-driven search campaigns in the Swiss market. Save the Children Switzerland was able to significantly increase its SEA performance and successfully position itself on Google in various subject areas, particularly in fundraising.
