Make money online: Annual Revenue of different websites
I don't know how many times in my life I heard someone ask me why I spent time to make website. I always answer the same thing : "To make money online". But then comes the question "How can you make money from it ? It's free !". It's not because you don't charge your visitors to use your site that you will not make money from it.
There is 2 major types of income on the web: advertisment and monthly fee. If you want your site to be free you will have to place banners that display ads. Advertising can generate a lot of cash if you have enough traffic. If you don't want to put banners, you will have to make your visitors (members) pay a one-time fee or monthly fee.
There is another way to make money with a website and it is by selling it. If you have enough of running your website and want to retire from it, you can sell it. Normally a website is sold for 5 times it's annual revenue. It can be sold for more or less depending on the potential of your website.
At first when I started my own (dating) websites I read a lot on the potential of those kind of websites. In this article I'll show you some stats about existing websites on the web and their annual revenue. I focus more on dating sites because this is that kind of websites that I have (iseduction and QuebecSexy).

POF is a 100% free dating site. It is by far the most money-making free dating site on the web.

If you want to see what it was looking on the past, just visit the WaybackMachine.

In the end...
In this article I only showed big websites that has been on the industry for years. If you start a website, don't imagine you will be competing with them at an early stage. You will be among 1000's of litle and medium sites a long time before being big ! I wrote stats for 6 dating sites but on the web we can find more than 1000 different dating sites. Because we can't really count them, the number may be a lot higher than this.
