Hi, Adsense earning is high and down in the same time! Here is a screenshot of the earning of two of my small sites: If you were in my place, would you close the low paying site and focus on the other one or keep them both?
I'd say that at this point you are getting too few clicks on both sites to be able to decide one way or the other, especially since eCPM tends to fluctuate. I'd say try to get your traffic up for both sites and see which is more consistent.
That same click you just got $5.16 may yield .07 in a few days so don't get too excited and start closing sites, just cause you think you figured this adsense thing out. take it easy RELAX!!
ur which site is under this CTR and my site gotoww.com alway under the CTR of 0.3 it's never higher than $1.2 and them what u will say?
That is a very big slide on your earnings on adsense. Sometimes Google is really having an erratic days... But it could also be on the performance of your ads on your blog.
Try to focus on traffic thru Search engine rather than social media or other referrals. Analyze the data for a longer time span and see what happens. I agree with Nonny, try to be consistent with your effort.
