Content
Write good quality content because "Content is King". The question is how much content can give you how much traffic. Its simple. You can get more than 100 visitors if you've a bit more than 1000 articles on your niche. These 100 or so visitors can give you 200-250 impressions daily. Now you can think what you need to do. Importantly, if you have not 10,000 monthly impressions then adsense can only do a little for you. There are big fishes who are earning 500$ a day. Its up to you. How big you can think?
