I just would like to get some ideas here. How much money from adsense which you get every month which you reinvest back into your site in term of advertisement (all kind/methods of ads ) I normally use about 50%. The balance 50%... i take it. But this 50% reinvestment ( if done properly) , generates more revenue for the site. I noticed that the visitor count increases... not very big jump, but at a steady incremental rate. I normally use the money for banner ads, paid classified, long tail keywords in adsense, and few other methods. By doing this, adsense income increases about 10% to 15% monthly. But due to this increment, the next month I have more money to advertise. I belive it could be made as a cycle. You put more, you make more. Been doing this last 3 months, its working. But I also do free advertising methods too like articles... but less.
