in the last days I’m seeing an horrible decrease in AdMob fill rate, localized in the USA.
I’ve always had a 98% fill rate, instead from tuesday I have a dropdown for United States from 98 to 76%, globally dropped from 98 to 90%.
Requests per day are the same, I have decreased impressions (obviously) and a costant number of clicks, with an increasing CTR (around 0.9% in thursday).
Having the same clicks and revenue, I didn’t worried too much, reporting errors I thought. But since tuesday and still no corrections, and only in the USA?
Am I the only one experiencing this problem? What do you suggest to do?
