Just the other day we learned Google was changing their AdSense referral policy. But we have reports that many Google AdSense publishers are already seeing these referral options not appearing for them. But many of those publishers are US based, so the policy doesn't apply to them.
This is likely a bug.
There are two threads reporting this, one at Google Groups and the other at DigitalPoint Forums. Here are some reports from the thread that confirm it is not just "AdSense Referrals" but other Google products that are impacting, and should not be.
Is anyone having this problem or is it just me? Today my adsense firefox referrals just disappeared and are no longer being displayed. I am located in the US so I shouldn't be affected by the new "rules" as per the adsense blog.
Recently I noticed the FireFox referral button dissapeared on my site, so I went into my adsense account and grabbed a new code. Works. Later in the day however the referral button dissapears again and this time using any code won't bring it back up. I thought it was my browser (which was FireFox 3 beta) so I used IE 7.
I am missing one Adwords referral button too right now and I in the US..
My other types of ads are working good though..
So it appears that some buttons are working and some aren't for select users. They all appear to be working for me.
