The most I have made online so far has been around $60 for doing random work online for others. I would love to e able to earn more online however it's finding the right kind of things to offer that people would be interested in and something that you know you could stick at.
A few dollars/pounds... I've never really tried properly to make real money, just a few things here and there that add up to barely nothing. Very soon I hope to be getting a regular income online. I have heard loads of stories about people earning millions through their websites, there was one 15 year old who set up his own web business and within a year had made $500,000
I do a ton of different things online and most of them don't pay a lot but I do monthly and yearly income reports and the most I've ever made in a year was last year (2012) and the exact total came to $600.75. Not much but every little bit counts. Plus I don't know anyone that would turn down an extra $600.
The two years before that I made about $300 each year.
