"After a total of 12 months of collaboration and an investment in the mid-five-figure range, my conclusion is unfortunately very disappointing. Before signing this contract, I had already been with another agency for 12 months. The sales manager here spoke very negatively about them, while simultaneously promising faster and significantly better results. Specifically, he said that with the six selected keywords (keywords 1-6), I could be in the top 3 within just six months. I believed him. After six months without the promised results, he admitted that these goals were not so easy to achieve. Fearing that the first few months would otherwise be a waste of money, I extended the contract. Subsequently, I was informed of new target positions – but these were largely missed. Objective comparison of target vs. result after 12 months: • Keyword 1 Target: Rank 1 → Result: Rank 1 (Start: Rank 2) • Keyword 2 Target: Top 3 → Result: Rank 6 (Start: Rank 5) • Keyword 3 Target: Top 3 → Result: Rank 5 (Start: Rank 6) • Keyword 4 Target: Top 5 → Result: Rank 19 (Start: Rank 34) • Keyword 5 Target: Top 10 → Result: Rank 22 (Start: Rank 51) • Keyword 6 Target: Top 10 → Result: Rank 33 (Start: Rank 84) Yes, there were improvements – but the agreed-upon target positions were largely not achieved. In the end, results count, not sales promises. Instead of clear results, we received justifications and excuses. I would like to give a special mention to Khashayar from Semtrix, who understood our frustration and provided expert support. However, this doesn't change the overall result. I'm deliberately not publishing our company's name. The bottom line is: a lot of money invested, but the promised and later redefined goals were not achieved. This review is intended to help other companies critically examine their sales promises."

"Semtrix GmbH provided us with excellent support with SEO optimization. From the initial consultation to the completion of the contract, and especially afterward, everything was very professional. You receive a very quick response by email, and they even call you back even if you can't reach anyone immediately by phone. When we encountered problems with our hosting provider during the transfer of our existing website, Semtrix GmbH created a much more attractive and professional website for us at a very reasonable price and in no way exploited our unfortunate situation. Our Google rankings for the agreed-upon keywords have improved dramatically. We recommend Semtrix GmbH to anyone who wants to improve their online presence and is looking for a friendly and professional team."
