All blogs and all websites earn different amounts from Adsense even with the same traffic since earnings from Adsense depend on the cost per click and the topic your blog or website is on.
Some website topics and blog topics pay more per click than others so one blog on a lower paying niche such as knitting may earn 5 to 10 cents per click while another blog that blogs about things such as health, insurance, finance etc may earn $0.50 to $4.00 per click.
So you could earn anywhere from $40.00 per month to $1,000.00 per month from 100,000 monthly unique visitors.
The key to earning good money with Adsense is to write a blog or website about things that are highly searched in Google and other search engines and write on topics that have a high cost per click.
Usually though once you get to 100,000 monthly unique visitors you can expect to be earning some money and even may get a payout from Adsense each month.
