The smell of money - niche markets
The AdSense publisher program is attracting every day more and more webmasters.
I have maked a test with a website to see how niche markets are working. I made a website about audio players and posted there reviews for players and hacks. I promoted the site and maked some link exchange with some website owners on the same market and submited to some free directories.
After 2 weeks of daily work i make at this moment an average of $5/day only with that site, and another $200/month from Amazon sales.
My advice: find a niche and work on it - the money will follow.
