You have probably read about some fortunate people with an income of over 1 million dollar per year only from Google’s Adsense

Webmasterworld has an interesting thread started by toldan called:

Adsense Millionaires Has anyone reached a million yet?

after a start, ezgo jumps in with some numbers:

If you mean make 1M in a year from AdSense.
so average. $83333.33/month
About $2777.77/day
Each click usually is from $0.03 to $2.00. Let’s assume averge $0.6 per click(I think this is still high) You need to have have at least 4630 clicks/day
If CTR is 1.5%. You need at least 308667 views on your site each day.

incrediBILL then ads more logic with numbers by addiing:

…Get motivated, you only need to make about $2,800 per day, which could be as easy as 547 web sites making as little as $5/day each…

Another interesting comment was made by Dollarshort who says:

Adsense now takes the back seat, I’m now making 4X the amount on an affiliate program.
