@AhsenAli What is new in this question!
Simply Make a Blog with valuable content then submit your site to AdSense to review it then they will give you a account. Where you will get your ads codes and put it on your website then for each legitimate click Google will pay you and you will be able to see your daily earnings in your AdSense account. That is the whole of summary of Monetize your website with Google AdSense.
Hope that will help you!
