Earn through AdSense

Start a website. Choose any topic you are interested most and can write with relax. For example if you can write on fitness, go and start a fitness advice website. Populate your website with useful content daily. Submit it into different search engines and directories to get few link backs. Remember, take care of your visitors and never thought about any money at least during the first month. Then go and sign up for google AdSense and embed AdSense ads in your website. Try harder, promote it and you’ll be getting $$ in your AdSense account.
Now start another website and double your income. Do it again and again. It needs time but it is the simplest method you can try.
