Right now, I get a check for $100 or so every couple months. I'm beginning to see the mistakes I've made and plan to correct that immediately.
Actually the earning is not stable at all. I have noticed, in some month the earning is increasing dramatically but in the very next month it is plummeting to a new low. I earn around $200 in an average from Google Adsense per month.

I can give you my niche, it's easy I have none with this site shetoldme.com it's the members's job to find niches and then post links to their web properties on my site. So that google sends visitors to my pages which are about lots of different topics, I don't know which niche is good or not, but as a whole, members are doing a good job because traffic is growing. At the moment it's over 5,000 unique visitors a day for a site just 6 months old.
