I have tried many services, but I chose Click.ru because of their comprehensive approach to work. They offer not only tools but also analytics, tagging, reports, documents, click fraud protection, parsers, and much more. The functionality is truly top-notch. There is also a rewards system, and at first, I was confused with the percentages and miscalculated my estimated cashback, as the percentage varies depending on the amount spent, the platform, and other factors. Now it averages around 10%, and sometimes even more.
