Google Retiring Referral Ads

Finally, the word is out - Google Adsense will retire Referral Ads which it introduced about a year ago. If you have been using Referral Ads, time to go back to the server and templates and start changing the ads. Replace them with the traditional Adsense ad units or else come August end, you will have a blank space staring at your face - matched by the drop in ad revenue from Adsense.
