There are several ways to earn money in AdSense. You can apply to AdSense through the blog. If your blog gets Adsense, you need to place the AdSense code. When the reader comes to read your blog, if they click on the ads, you will get money from it. Ads will show on your blog through google. Your main goal should be to bring traffic to your blog, as much traffic as it will earn.

But you should not ask your friend or family to click on ads repeatedly for more income. If you take an invalid route hoping to get more clicks, then Google will terminate your Adsense account. Once the AdSense account is canceled, it becomes much harder to get it back.
