For those who are already working with this company or planning to start a partnership, it's worth paying attention. I encountered that their algorithm provides incorrect data. In customer support, I gave an example where the algorithm showed a competition level of 2 for a keyword, but in reality, if you enter that keyword in Yandex, you can see that all the sites in the title contain it. This indicates that it's impossible to reach the top for that keyword. Mutagen acknowledged their mistake and refunded me all the money I spent on using their service. They deleted my account to cover up the traces of the checks. It's unknown how long Mutagen has been deceiving users in this way. I recommend everyone to stand up for their rights. Mutagen should be held accountable for the errors of their algorithm and refund all clients. Be careful, friends. Here’s a small selection of keywords that show competition levels of 1-2-3, but in reality, you won't make it to the top with them: "DIY parquet board installation step-by-step guide" 1, "which side to lay vapor barrier towards insulation" 3, "vapor barrier for ceilings in wooden floors" 2, "can you glue wallpaper on water-emulsion paint" 2. Demand a refund from them! This is a scam!
