My adsense income has dropped like a stone by 60% sharply at the end of March, from one day to the next. Until March 28th the income was hovering around a certain level, since March 29th the income has been hovering at about 40% of what the previous level was.
I didn't make any changes to the site, besides adding new content on a regular basis which I have been doing for years. I haven't made any changes to the ads (format, settings etc.)
The page views dropped a bit, but no by so much. The real issue is the page CTR which seems to have dropped to half of what is usually was (used to be around 1.something %, now it's around 0.5%).
Do you have any suggestions what might be going on?
