That's a very frequent question: "If I rank in top 10 / top 5 in Google, how much money will I make?"
There are so many "It depends" here: Where exactly will you rank? #1 is not equal to #10. In fact ranking in top 10 is too vague!
Also, how is your site making money? Are you selling your own product or do you monetize through ads?
Lastly, it depends on how well your site is optimized for conversions.
The CEO of Internet Marketing Ninjas Jim Boykin is performing some conversions to give you some average.
The bottom line: Invest in your offering or your product, NOT in rankings!
