I've got a link shortener site with roughly 10k visitors a day. Nothing special, no extra functions, just a simple free script and some link building through article directories. Made some good money from AdSense but they decided to ban me and I've had nothing but trouble since. Tried a few different methods but can't even reach a dollar a day even though I used to make around $50 daily. I'm not interested in getting a new AdSense account so I'm wondering if you've got any ideas or experience about this. What would you recommend without annoying the hell out of the users. Don't want to sink the ship.
