it depends on how many clicks your site could make, and how much cost per click your adsense keyword. you can answer it by your self
It depends on so many different things such as keywords, ad placement, content, click location and many other factor exist.
well, it's depends upon territory. if you have unique 1000 visitors per day from Europe side you will earn 5 to 10 dollars, it's very easy earning money from adsense but you need unique content and unique visitors, you need to show authentication to Google increase page rank of you website or blog then you will earn more money.
US, UK, Canada, Australia traffic will give you around $3-5 while sub continent traffic may get you less than $1 for that amount of traffic. It also depends on niche. Normally, entertainment niches pay less while Finance keywords may much better.
It honestly depends on what keywords you're hitting for. If you're hitting a high value keyword, you could make a nice chunk. Otherwise, 1$ a day maybe.
Earnings depend on site topic, CTR, no of clicks, ad placement. You can earn from $0-$100, totally depends on your site.
I have 400-500 unique visitors everyday and I am making $250-$350 per month from adsense. My site is a business directory with mixed niche. This should give you some idea how much one can make from adsense.
That depends upon your RPM, for a country like India RPM is around $1.50, but for US and UK it is around $4 to $5
Sounds some hope, otherwise I have very bad notion upon adsense, only waste of your space in webpages and thought it would be a wise choice to get directs ads from parties(product, service etc).
