Does anyone have any ideas as to what I might do?
How confident are you that all supposed visitors are genuine?
I have been ruthlessly locking my sites down and my CTRs and eCPMs are the best they've been for years YET my actual PIs and bandwidth (multi GBs) are way lower than ever.
How much of this has to do with, for me, an algo change at the beginning of October whereby all my thousands of images after 10+ years were removed from their SERPs...!...I have absolutely no idea HOWEVER my earnings seem to be now back to "normal".
Seriously, look at how much stuff is being leeched from your site(s) BUT still being recognised by AdSense as PIs...many, many, many of mine were attempted hotlinking of images...one image alone 200,000+ in one month!
Check everything, if it does not apply to you, fine, if this helps anyone else, check it.
