Games were always popular on the internet and now more and more games are online and free for the people to use. Most of these free gaming sites are very popular and new are coming up all the time. So the question arises. Why a webmaster will build such a site. As always the answer is simple. Money. Because these websites become quite popular very fast especially with some kind of advertising promotion their repeating visitors user base is growing fast. The result is thousands and thousands of hits every time and this easily converts to clicks and money for the webmaster.
On the other side building such a website is not very easy except if you buy a commercial package with thousands of free games. But doing this you are competing with a thousand other websites that are using this software as well. This is not good in the eyes of the search engine bots because of duplicate content and other issues.
Talking about return of investment for such websites to my knowledge is very low or in some cases very late. With all this competitions this kind of websites cannot depend on search engine traffic and must rely on paid advertisement. Until the user base will grow large enough the return of investment is poor. An example of such a website you can find to the following link. Free games online.
By taking a look in his alexa stats we can easily see that this site is new and search engines just started to index it.
Let’s wish it good luck!
