Who knows why the number of ad impressions, as well as the CTR on YAN, drops dramatically over time and how to increase them?

Question

contextual advertising

Good afternoon.
I ran into a problem: in a week, the number of impressions of ads in YAN in Yandex.Direct decreased from 144,000 to 55,000, CTR also fell from 0.5% to 0.2%, and the number of page views also fell from 7 to 2.5.
I didn’t change anything in the settings, texts, 20 ads work in groups. The rates have been adjusted, but only slightly.
Can you please tell me if you faced the same problem and how did you solve it?
Thank you!
