How should I set up the YAN?

Question

Yandex.Direct

Is it worth it to expand the keys through programs to MF AND LF?
Or is HF enough? (I have taken keys from 10k-50k)
At the moment I have about 60 HF keys, 1 group of 7 ads has been created for them, which Yandex shows at its discretion.

Answer 1

Worth picking up and checking. There will be few impressions where - Yandex will remove it.
