Mutagen will be useful for copywriters, marketers, webmasters, and SEO specialists. I recommend paying attention to this service, as I use it quite often and believe there is no simpler tool for finding competitive keywords. To start checking, you need to register and top up your balance, and then everything is quite straightforward. There is a detailed instruction and an FAQ section for beginners. You enter your query, and after the system analyzes it, you receive a brief report that shows the competition level of the query (based on the analysis of the top 30 Yandex sites), the number of views, and the number of long-tail keywords (not exact matches for the query). The lower the competition level, the easier it is to get into the top. If the competition is high (for example, 20-25), it's better to use long-tails with a lower value. The service is paid, but it's worth it; I recommend it.
