I'm struggling to understand what has happened. CTRs were between 4% to 8% across various sites from 1st Jan to 12th Feb. Since the 12th of Feb, they have been at 0.5% to 1%.

Obviously, our revenue has plummeted. It's the same sites and we get our traffic from the same places we always have (social media, organic search, repeat visitors etc.) so why would the ads suddenly be unclickable?

I've looked at our sites through various proxy IPs as our traffic is worldwide, and the ads I see look relevant and perfectly fine for all countries I checked.

I have non-Google Network advertisers turned off - but I always have. I have various categories blocked - but I always have. The ads are the same size and in the same place. Just suddenly, on the 12th of February, no-one wanted to click the ads any more? It's been over a week now.

It doesn't make sense.
