How can you earn money by just making a website?

I heard that some people make money by just making a website. How is that?

Put advertisements on it and everytime someone goes to the website or in some cases they must click on the advertisements you will get so much money... usually its only a few cents each time but if its a good website and somewhere people will go it could really add up.

Pay per view.

They put ads on the site. Look at all the ads on the web. They're making that website money.

everytime someone clicks an advertisment on your site, it makes money. try google adsense.

Ad sense from Google is the best way to earn money with your website. Once your website is approved by Google you will get advertisements in your site and can earn money. The important thing is your site should contain good and rich content to attract more viewers, which will turn into clicks in the advertisements published in your website. It is a good way to earn money
