I believe my websites are under a new kind of invalid traffic attack that generates invalid clicks on Adsense. There has been some news report on this recently:
Our websites are based in south america, and all of a sudden last week we started receiving high traffic with over 90% bounce rate and ridiculous CTRs on Adsense for United States. US is not a targeted audience at all.
I wonder if there is any way we can intensify bot filtering specifically for US IPs?
What would you guys do in my position?
Thanks a lot
