It all depends on your niche, ad placement and CTR. $3 from 15 clicks is really a good EPC, so, you need to work on getting more traffic.
this is not really normal and i want to tell you there must be some problem with google adsense because i m daily working on my blogs and i didnt get any money from that and yeah it is not normal because i was getting $5 with 1000 impressions everyday now i m not getting anything
It's really depends on many factors, I got one of my site has page impressions few times more than you have but get less clicks. This mainly depends on how you place ads and whether there are enough interesting ads for your kw ( content). So you should monitor and filter ads from time to time.
Like people have said, much be your niche. The keywords the crawl bots are grabbing are generating ads the have low cost per clicks.
Your site is a forum which usually has low CTR. So I think your earning is quite normal with that much traffic for a forum site
http://slayo.com/category/adsense-seo check this, I have wrote based on my experienced about how to make adsense ads relevant, the best place to put adsense and combining adsense targetting with SEO.
i hade seen a lot of sites like pay to click but its not trustable things its only a time wastage nothing else i think
since its a forum thats why it has such such a low ctr, try to place your ads in different spots to see if it increases your ctr.
With that many impressions like that I'm no wondering since it is a forum site. Agree with people's opinion above, try to replace your ads position regularly.
it all depends on niche... my fren. I was getting 41K uniques and only 50-60 clicks earning less than $10. Its all niche u choose...
The standard earning from adsense is like for 1000 Page Views you should get nearly $3. But it depends on many factors like origin of traffic, Niche of the website,ads placement etc.
you can try experimenting on your ads placement..but remember. adsense on forums will not earn well..
Your CTR is pretty low. Where did you get the traffic from? Is it from social bookmarking sites or search engines?
One of the reasons for low earning is irrelevant ads by google because, your site is new. Google might take time (Its automated system) to figure out which ads works best on pages.
using VB wont effect your adsense earnings, it depends on your site niche and traffic source, ad placement. make sure you have better ad placement in the future. and see what you will have! good luck!
