Alytics.ru has proven to be quite effective in its work. I use it often, and now, thanks to this tool, I can analyze and optimize advertising campaigns on Yandex and Google without much effort. I admit that this tool has extensive capabilities, and it would be great to add detailed statistics to the reports, but quality analysis requires some time spent on settings. Considering all aspects, it has significantly increased the efficiency of my advertising and helped to substantially reduce costs.
