How & why a website owner gets profits when the users access that particular website?

you either get money from advertisers to advertise on the site, or people pay to use the site. if neither of those, then it's your money.

Well what kind of website do you want to make? And who is your target? When you find that out, you need to place relevant links to your site on all related websites to drive traffic to your site. THEN, once you have a descent amount of traffic, you can use known pay-per-click ad sites like AdBrite or Google's Adsense to place advertisements on your site. The more people that go to your site, the more likely they are to click on the ads and you will get paid after a certain amount. If you grow to a large amount of traffic then you can make a deal directly with anyone who wants to advertise on your site with an agreed amount of money and method of income (charge flat rate per x period of time or per click).

It really depends what type of website it is. There are the websites that offer premium memberships where a user has to pay to access that website. The most common way a website earns money is by advertisements which is why you see it on most websites. There are three types of advertisements: *Pay per click is when the website owners gets paid every time a visitor clicks on the ad *Pay per thousand impressions is when site owner gets paid every time the advertisement is seen a thousand times *Pay per sale/ lead is when the site owner gets paid when a visitor buys a product advertised on the website or performs a specific action like answering a survey after clicking on the advertisement.
