ctr is very low. It depends on your niche how much you can earn, but no matter which niche it is, with this CTR rate, you are earning like %10 max, what you can actually earn.
Clicks are good, but page views are not enough to earn well , according to my knowledge but i can say it like under 150 to 200 $ a month ?
CTR is very low, you should get a prof. suggestion with your ad placement to have a higher CTR. You should earn at least 2-3X more.
what i mean is, you should actually get more clicks with this page-view numbers. You should get a feedback about your ad placement on your website, so that you can get more click with the same pageviews. This is what i mean. Basically, you should make changes on your ad placement. And you should get professional suggestions, so that it prevents that you are get banned from adsense but also you can get more clicks on your ads.
Page views are good and CTR is decent, but CPC is very low, which is most likely because of your niche. However, my experience from last few weeks is the same - from CPC around 0.30-0.40 down to 0.6 - 0.10 (very f. bad) and the niche is usually good paying /at least was so far/ - travel. This of course is likely to be due to the lower bids from the advertisers. Still depending on your niche I'd recommend you to forget adsense and try some affiliate sales. With 20K page views per day you can achieve some good results, depending on what KWs and where you are ranking for them. Info about your niche will help more... Good luck!
I noticed your site was a forum. I read somewhere that forums had a lower ctr than non forums using adsense. You should listen to abraxas's idea about the affiliate sales.
I haven't worked within your niche (finally saw your post with the URL), but you can have a look around Commission Junction (cj.com). Most likely you will find better affiliate programs, I cannot recommend you simply because I am not familiar with that niche... Actually what about amazon? Haven't worked with them so far, but maybe it is a better idea?! Maybe you can sell some electronic gadgets? p.s. 10-20K page views per day are way too much to waste 'em with 50-100 so cheap adsense clicks........ If you make couple or even a single sale per day, it is very likely that you will get at least the same result+! Check out the available options and give it a try
