Alarm bells have been ringing for many AdSense publishers this week after CPCs dropped by up to 75% over the weekend. The unprecedented drops appeared to be hitting one traffic geo at a time, starting with the US and Canada on Saturday.
Although dramatic, the drops have not been universal. The drops were widely reported to be affecting AdWords impressions from particular Geos, but many publishers escaped untouched. In fact, despite widespread reports of the issue our sample across AdSense publishers who’s data we can access showed a slight aggregated increase at the weekend.
The good news for affected publishers is that the issue has now been resolved by Google, but this was a drop in earnings rather than a reporting problem. That means that the bad news is that many publishers will have earned less whilst affected.
Communication from Google about the issue hints at deliberate manipulation by some buyers:
Over the past 48 hours, a number of AdSense publishers alerted us to an issue with declining cost-per-click for ads on their sites. We were able to identify the cause of the issue quickly and resolve it quickly: Several ad buyers were using irresponsible campaign parameters, lowering query coverage for specific creative types in some countries. The ad buyers responsible have been blacklisted and impacted publishers should see that their coverage is back to normal in their AdSense account.
Quite what “irresponsible parameters” were used is unclear. There has not yet been any statement to offer re-assurance that this issue has been resolved in a way that would prevent other ad buyers having a similar negative impact in the future.

Not sure why all of you are complainig about adsense it is working fine for me.
How can I achieve high cpc rate for my website.
After the new update of adsense my website is completely disabled on ad showing, my ads are limited by adsense, help me to move foreword
This issue won’t be related to the topic of this article. However, if you are seeing no ads on your website and are convinced that your adsense code is correct on page then you need to log into your account and check for policy messages.
Glad it recovered back. on that time, My business wasn’t that big enough to match up with the results in drop of CPC. anyway, its perfectly fine now.

This results in losing thousands of Money to Publishers.
I am having the same problem too, ever since the drop, CPC yet to recover.
Hi there from Germany…
Is it possible that non-english-speaking countries are effected delayed? On August the 6th and August the 7th 2017 my CPC, RPM and CTR seem to be normal. CPC starts dropping slowly on August the 14th and crashed down another 30% on August the 27th.
Has it recovered? The issue detailed on this page has been rectified and although CPCs on the affected days remains low, they have recovered since.
aha thanks!!
Man, so little info on this. My CPC dropped too, approximately 30%. I think it will take a few weeks for CPC to go up again?
