Yeah! I know it's normal. I'm just expecting advertisers to return from Holidays soonGuys it's normal, advertiser know that people spent their money during holidays. From mid-February things will start to get back to normal.
I am from 150e/day to 40e in terms of earnings even if the CTR it's the same. CPC for some kw went from 1e/click to as low as 0.18-0.20.
Nothing to worry. Just continue to work.
