It's that dire.
After reading about your awful Adsense experiences for a long time now... I truly believe you will start seeing negative earnings very soon. It's that dire.
How can everyone be experiencing traffic down unless there is an overall non-searching for these products?
This would seem to be one of the answers judging by how many businesses have closed in the last few years, 33% in the UK alone,
