I manage several projects in Yandex Direct and VK. I decided to try a service to protect my ads from bots, as the number of strange clicks and applications had become too high. The setup took about 5-7 minutes: the code was installed similarly to how it's done with Metrics, and then the system functions automatically around the clock. I activated protection for ads in Yandex Direct and VK. In the first month, CPA decreased by about 25%, and the number of invalid applications dropped by about 10%. I spoke with the manager Alexey, and later with support (I also reached out to Vladimir), and they provided recommendations on segments of the bot database. Yes, sometimes the service may affect a few real users, but that's a minor error.
