$20/month. I sold that site and am now working on another project that I hope will bring in more traffic and therefore a higher monthly adsense income.
My highest so far is just under $300. I have about 15 sites, so this isn't too good really. It is increasing though.
Why are you so obsessed with blogs? If you get a lot of traffic you can potentially make good money, it does not matter whether its a blog or a site.
My site is new. Tell me anyone that how I can increase traffic on my site sothat I can earn more from adsense.
There are some big earners. They just don't disclose what they earn. Some of them have actually said in the past how much they earn, but they probably don't want to repeat themselves over and over again.
Just short of $200 last month and I am at $150 for this month... so it's looking like it will be $330 - $400 as traffic is growing steadily. I am hoping to hit $1k/Month in the next 2 - 3 months.
