Google Blacklisted Advertisers after Driving Down CPCs
Meanwhile SearchEngineLandGoogle report says that Google has already noticed the trend, and found out that some of its advertisers were indeed responsible.
The advertisers exploited the system to drive down Cost Per Click on Ads, which has negatively affected publishers’ earnings.
Google has addressed the issue by blacklisting those ad buyers and identified the issue going forward.
The advertisers were using “irresponsible campaign parameters,” which led to their being able to lower the query coverage for specific creative types in some countries.
“This was not a user interface bug or reporting glitch, Google confirmed. The CPCs that were relatively low for publishers over the past few days will not be updated, but going forward, you should see CPCs that do not surprise you.”
If noticed this, you’re not alone!
