Google Adsense Bug Showing No Ads on Sites

Are Google Adsense Ads not showing on your site? It seems an Adsense bug is affecting many Adsense publishers which is causing no ads to display for last many hours, which is leading to loss of revenue for many Adsense users. We are also seeing no Adsense ads on our site, but only blank ad spaces (check this post on our site yourself).

No  Adsense Ads

When I found the issue, I was surprised and at first it stuck me that its possible the ads were disabled. Then quickly checked my email for any Adsense warnings for policy violation etc., but there were none. I though it might be a browser issue, cleared the cache, then checked my site in other browsers – no ads. Then I checked the site in my Android mobile phone browser and still no ads.

Then I tried to see if the code was properly inserted, as sometimes you can break the code if you use WYSIWYG html editors. But the code was inserted properly. Then I went searching for possible causes for non displaying Adsense ads, and Adsense Help provides some answers like

1. JavaScript disabled in your browser
2. Personal firewall software with ad blocking / other ad blocking software
3. Disapproved site
4. Pages with potentially adult or mature content
5. Adsense policy violation
6. Account risk to advertisers or generating invalid clicks
7. Too many ad units on your site

But we always take care to strictly adhere to Adsense policies as it is an important advertising  revenue source for this site.  When I checked the Adsense account, the earnings were not zero, in fact Adsense Search was generating clicks and income. Indeed the Adsense ads were displaying on the site, and Adsense for Search was actually showing ads.

Then I posted to Twitter and checked the forums and realized many people are affected and a member roycerus says they have “verbal confirmation from Adsense directly” and this is an “Adsense bug which is being corrected [no eta for a fix yet] and many sites have been affected”.  Even the Adsense forum is full of such complaints and requests.

What is strange is that Google Adsense has not put up any blog post or update informing Adsense publishers of this Adsense bug as many webmasters and bloggers panic for fear as that their Adsense account may be disabled. It will also be interesting if Google Adsense team plans to reimburse publishers for the revenue loss, as some big publishers are losing thousands of dollars every hour!

Is you site affected? Do you see Adsense ads on your sites?
