My goal is for $100 daily, but I'm not expecting to make this for a year. I'm going to put serious effort into this maybe 5 hours a day, I've finished uni and am postponing getting a job until I can decide whether I will make good money from Adsense. I'm targeting fairly competitive niches rather than going for lots of micro niche sites, I think this is the better option in the long run.
* Choose a good niche * Create a good site in that niche * Get lots of visitors to it * Add Adsense * Tweak the Adsense to get the best CTR hehe perfect idea.
