One month Adsense has gave me an average of $0.20 for each click, and from this november I noted that the money I am earning is very less even there are considerable clicks. The average money per click is way down to $0.05 and some times it is $0.01. This is irritating me a lot. Is this a temporary one or a permanent one. If Adsense pays me like this in future then I have to re-think about it. Also suggest other CPM advertising programs please!
It is normal for the low pay niche. You might try on bidvertiser which allow you to choose the high pay ads
it could be due to advertisers paying less because of the current economic conditions, because a fair few people have been saying they are experiencing less per click.
