Best I made was around $400 in a month, wish I could that every month but I lost motivation and I'm only getting back into it now. Still doing $100+ a month though so I'm happy !
define: a living it really depends, I'm sure some of the richer digitalpoint members would say anything under $300 a day isn't a living to them. I make a decent amount, I wouldn't consider it a living and I don't think minimum wage laws here would consider it a living either. But it's better then nothing, and I haven't spent a dime of it, just saving it till I can think of something stupid to splurge it on. From what I've heard from the early adopters of Adsense, the riches are not as great as they were when Google was willingly to work with webmasters a bit more, now it's more about advertisers and turn-over rates. So it's best to always look for other monetization options, but Adsense will net you a decent somewhat stable amount - so congratulations.
Thanks GarySinh, now I know why I started this thread, for a moment I thought I was telling people about a useful service that makes me money. If anyone knows of any other service that makes good money take my advice and don't post it here.
