I compared the ad reports between two periods - in the old forum (2017) and discourse.
It looks like a combination of several factors are at work.
- A tenth of the earnings is THE problem of course.
- Fewer page views that never got back to the old numbers
- Even fewer impressions (the result of some blanks?).
- A quarter of page views but only a sixth of clicks - clicks’ drop is steeper.
- Lower CTR - why?
- Lower CPC - did it generally go down over the years?
