I haven't encountered a better service for developing a website promotion strategy in the Russian internet. I like that I only pay for the actions that are truly necessary. Usually, I conduct an analysis of donor sites, exclude low-quality ones, and create a whitelist of suitable resources. Based on this, I plan further promotion. Prices vary, but I can say that they are quite reasonable; automated checks are cheaper than services from live people at PR agencies. This allows me to save both money and time. The weekly check on Seolib includes an analysis of the site's positions, keyword research, evaluation of the quality of external links, and analysis based on TCI and PR metrics. In the end, a full check costs about 5 dollars, which is quite inexpensive. There are many analysis tools available—around 500 for new users—allowing for detailed examination of each page, working on tags and meta fields, which is cost-effective. This helps identify which pages are most interesting to visitors and develop in that direction. The system is very useful and functional; for this price, I haven't found anything better in the Russian internet, so I regularly work with it.
