for the past one week i noticed that CTR has gone down by 50% ... I read it at another forum there seemed to be an issue with Adsense can anybody here confirm this too ?
I don't think there is any issue with AdSense. If there was a problem then everybody would have faced it. CTR vary a lot. Go with weekly average assumptions.
You dont have to worry about it just try to get more and more traffic to your site and blend it with a site
That's odd. Did you change the placement or the colors? Maybe the hype around your product died down.
also too advertisers could have changed up a little bit so it's possible some of your ads are no longer as relevant as some of the ads that were displaying on your site before that were converting. It's the ebb and flow of adsense
