Frewert Media GmbH - SEO & Online Marketing Agentur

I've worked with Jonas Frewert on two SEO projects – and I can only say: consistently excellent experiences! Precisely because SEO is a matter of trust and success doesn't happen overnight, you need a professional who thinks along, analyzes, and provides long-term support. Jonas brings precisely this experience. Each project is approached individually, reacts flexibly to changes, and the strategy is always adapted accordingly. I was never disappointed – thank you for the great collaboration!

I completed the agency's Udemy course on Google Ads. It's clear that Jonas has a very deep understanding of the subject and—very usefully—can also apply this knowledge to practical advertising campaigns. I really learned a lot. His approach is friendly, professional, and trustworthy.

I enrolled in Jonas' SEO 2026 course on Udemy. I can wholeheartedly recommend it. I started a blog four weeks ago and wanted to get SEO right from the beginning. The course is a mix of theory and practice. Jonas explains everything very simply, and I was able to follow along at my own pace. There's even a bonus, which I found extremely interesting. I've already implemented some of the techniques on my website, and my metrics have already increased from zero. I'm excited to see how things develop in the near future and am happy that the course filled in some of my knowledge gaps. Thanks, Jonas, and great work! Best regards, Carolin
