I have blog that has 3000 visitors a day and I earn 50 dollars a day. To earn 15000 a month you need about 30 000 unique visitors a day and it makes about 1 million a month. Of course it depends on the niche. If you have a general blog you may need 3 million visitors per month.
It depends from content to content, all advertisers who are using adwords are not paying the same amount, for some content even a single click will earn $2, I had earned nearly $500 a month for quite a long time for a job site
Well, first of all, traffic and adsense earnings have no relation with each other. You could have the highest visited site but it doesn't mean that people will click on your ads. All you need in a good site with the right amount of views and perfect ad targeting and hopefully those interested will click the ad. best answer
it depend your content type and quality. if you publish good quality high adsense keyword basis website then you get more cpc.
It is too small because of his niche and his targeted traffic. Target a high pain niche and US traffic to get a high paying rate.
