I don't understand this coachm, traffic volumes the same but earnings decimated?
One previous suggestion was that you may have a different audience but that seems far-fetched. Maybe the factor influencing the drop in income is that the ads served on your pages have suddenly changed in nature.
But that doesn't match your remark about a similar drop in income from Amazon. Unless the Adsense ads driving traffic to Amazon have also detrimentally changed.
Even if the above was the case, I can't offer even a thought as to how to correct the situation.
Good luck though, same volumes in traffic but a massive drop in income seems very unfair.
