Google Adsense is free. Step 1: Set up a website. Step 2: Create an adsense account via a google account Step 3: connect your adsense account to your website and get the code for placing ads - 4) There is often a wait period before adsense will place ads on your site - they want to know that you are posting consistent content 5) once approved, ads will appear on your site and when people click, you'll earn. I blog at tnedreport.com and have been using adsense for a long time there - it's a reliable source of income.
