Selected reviews. You can read every one of them on the public profiles:
Trustpilot“Good analyses, well-developed concepts and good, professional execution of the plans. Regular video calls round off the good support.”
Trustpilot“We are a B2B SaaS company and have been working with Trustfactory on our Google Ads and SEO for more than a year, and we can recommend the collaboration without reservation. The whole team stands out for deep expertise, fast communication and proactive suggestions that always serve our goals. We would especially like to mention Gökhan, Philipp and Mijo, who have looked after us competently, reliably and with great commitment throughout. If you are looking for an agency that doesn’t just execute but actively thinks along, Trustfactory is the right place. A clear recommendation from us.”
Trustpilot“Outstanding advice on SEO and competitor analysis. I am very satisfied and can definitely recommend Trustfactory.”
“We have been working with Trustfactory for about eight months. During this time we have seen a clear improvement in our domain ranking on Google. Trustfactory stands out for professionalism and reliability. The regular meetings are effective and provide valuable information. A first-class provider in SEO.”
Trustpilot“Great service. Everything worked as promised.”
“So far only very good experiences with Trustfactory. Great work and super support for our online business!! Great work and great support month after month, highly recommended!”
Trustpilot“Super! A great short consultation with an honest result, I thought it was really great :)”
Trustpilot“We have been working with trustfactory for quite a while and couldn’t be more satisfied. The whole team simply deserves a really big compliment, especially our SEO consultant Jonas. What you have built and offer us as clients is simply outstanding. With other service providers you often feel like you’re slipping into mass processing. With you it’s different. We value the personal contact with you, our regular meetings and above all the extras you offer us on top (e.g. the free SEO Academy). And all of that on more than fair terms. We are sure that we will be working together with you for a long time!”
“Very good service, fast and competent advice.”
Trustpilot“Very good support”
Trustpilot“I have been working with Trustfactory for almost a year and I love this collaboration. They are a young, passionate team that tackles every project with full commitment. The cooperation is not only successful thanks to Trustfactory’s focus on goals, it is also enormous fun. I hope for a continued successful and awesome collaboration.”
Trustpilot“Phillip Mettman from trustfactory is a numbers person and clearly has a lot of experience with “getting found on Google and AI” and a lot of expertise in SEO. In a pleasant conversation on equal footing we took away a lot of information, and Phillip took the time to work out what is best for our company, without trying to push his offer on us.”
Reviews.io“Since we started working together, our traffic and SEO numbers have improved significantly. Transparency and communication are very professional as well. Thank you, and keep it up!”
“Absolutely satisfied with the service. We have regular calls, and my SEO numbers improve every month. I see Trustfactory as an absolutely transparent and reputable SEO agency, and everyone knows how many dubious companies there are out there in SEO. When I have questions or something is unclear, they make an effort to clear it up right away. I have already recommended Trustfactory to colleagues. […]”
Trustpilot“Have been working with Trustfactory for more than a year and can only recommend them for SEO in the DACH region.”
“I have been working with Trustfactory on SEO for several years. The team is extremely professional and experienced. This also shows in the excellent results we have achieved together so far.”
Trustpilot“I have had great experiences with Trustfactory. The team does very good work, is there for questions and is reliable.”
“A strong agency and a good contact person. As an agency owner myself, I can certainly confirm this.”
Trustpilot“Thank you for the friendly contact.”
Reviews.io“Great SEO agency, recommended for anyone who wants to do SEO in depth. Strong know-how and friendly service :-)”
Trustpilot“I gave Trustfactory a completely new website without trust, authority or any other SEO-relevant data, and within three months the result was already excellent. Domain Rating keeps rising, and with it the rankings and the traffic. Communication is first-rate, and that is everything I expect from an SEO agency. […]”
“A client for almost 3 years, with a break in between. Outstanding customer service! No other SEO agency comes anywhere close in performance and customer satisfaction!”
Trustpilot“We have been working with Trustfactory for half a year now and have had only good experiences so far. From communication to delivery, the workflow runs perfectly! Big praise to Daniel, who is driving our SEO project forward with full energy! We will keep working with Trustfactory and try to build further on the great successes of the last months 👍”
“During the enquiry phase, a very open and honest conversation about potential. Good, relaxed atmosphere. Even though we decided not to work together, they gave us some tips and help. For a small side business the agency is less suitable, because the budget required is too high.”
Trustpilot“I had around 20 comprehensive guide texts for product categories created, including the briefing. The texts were then written in a very transparent process. I always knew what the next step was, could step in with corrections and make suggestions for improvement. A really successful process with excellent texts, all of which also entered the Google rankings well.”
“I find it a good collaboration: clear goals were defined, and they are always analysed with me in great detail. I also really like that everything is included in one price and there are no extra costs. The dashboard also shows me very precisely where things stand, and questions are answered quickly. Unfortunately, at the end some budget was left over and we couldn’t change the contract early, so we had to switch to other goals.”
Trustpilot“We are very satisfied, and our website has reached good visibility in Google search. Trustfactory works transparently and with focus, with good regular reporting.”
“Very good SEO consulting and analysis.”
Trustpilot“First-class.”
“Very professional service. Have been seeing great results and am very happy with the service I have been given.”
FAQ
Questions about our reviews

Your question isn’t here? Ask Philip in a free strategy session. He replies within one business day.
How many reviews does Trustfactory have?
383 reviews with an average of 4.8 out of 5 stars (as of October 2026): 173 on Trustpilot (4.7), 96 on Google (4.7), 73 on Reviews.io (5.0) and 41 on ProvenExpert (5.0).
Do you show every review here?
No, a selection. Each one is shown as published, with platform and month; reviews written in German are shown in translation and marked as such. Every review shown here, and the lower-rated ones too, can be found on the profiles: Google, Trustpilot, ProvenExpert and Reviews.io.
How is the average calculated?
Each platform counts with its number of reviews: 173 × 4.7 (Trustpilot), 96 × 4.7 (Google), 73 × 5.0 (Reviews.io) and 41 × 5.0 (ProvenExpert) give an average of 4.79, rounded to 4.8.
Why do you count only 41 reviews on ProvenExpert?
The ProvenExpert profile also shows reviews imported from Trustpilot. Those are already part of the Trustpilot number, so to avoid counting anything twice we include only the 41 reviews left directly on ProvenExpert.
Who speaks in the videos?
People from our clients’ companies, on camera and in their own words (in German): owners, board members and marketing leads. The result next to each video comes from that client’s case study. Where the same person or company also left a review, it appears below the video, translated from German.
