How to protect ads from being clicked by Direct YAN?

Question

Yandex.Direct

How can you protect Rya ads from clicks and increased activity. We have been working in rye for 3-4 months. Over the past 2 weeks, traffic began to go 2-3 times more from there. Applications are gone. Money began to leave 2-3 times more than usual.
We started using the clickfrog.ru service.
So far, it has been used for 2 days. Added 4 ip addresses that made about 50 clicks in the last 2 days.
But the situation is not yet changing for the better. More than half of the visits are dead visits at 0.0 , 0.01 etc........

Answer 1

It is likely that it is not a matter of clicking. Yandex.YAN is becoming a very poor source, and it's more about sites. Every day there are more and more sites with large volumes of traffic, but low quality. Here are mobile applications, and the city Wi-Fi portal (if you are located in Moscow), advertising in mobile browsers.
You should analyze and test the work without such sites. See how applications are received from the Wi-Fi portal, from zen.yandex.ru, images.yandex.ru, mobile applications (names begin with com. and ru.). Segment the received traffic by device. Is there a difference in bounces and conversions between conversions from mobile devices? Perhaps you should put a negative adjustment for mobile in campaigns.
Remove third-party mobile app partners from sites: Smaato, Mopub, MobFox, Inner-active.
Sometimes such actions manage to save YAN campaigns.
