How to earn money in google adsense? -

It takes time. You would need to do some research, find a niche topic to create a website about, and then put the adsense code into your site. I ve been doing it for four years and make the most from niche sites. Even though I make some money from it, there are other ways to increase the profits online (for example, being an affiliate and promoting a product for someone, make 50% commissions on all sales through your link)
