I searched for and compared tools for a long time, specifically for the Russian-speaking segment. Although there are quite a few, the truly quality ones can be counted on one hand. After studying the functionality and reading numerous reviews (it was this review that prompted me to try the Seolib tool), I want to note that everything mentioned in the Seolib reviews and independent surveys really corresponds to reality. The prices and features match. However, there are some questions about quality, especially regarding the speed of working with large volumes of data and the response time of technical support. No one is perfect, and Seolib certainly has its place in the SEO services market. The decision to use it is up to you.
