Does advertising on one's site work ?

What do i mean by making money on the Internet?

I simply mean the get rich quick ones am not saying that good websites,blogs etc, with good content does not make money they do make money. So that explains why i have advertisement's on my page am not trying to get rich quick. I don't expect much returns from it either. Now AdSense , ad volcano ,Cpx advertising, yahoo advertising and all are genuine advertisement providers that is they provide advertisement to people like you and me and share the income that is generated thus. Each have their own methods of going about the deal but that is the basic idea.
Now when can we say people abuse this proper act of displaying other peoples content ones site, simple when they abuse the system. Why would some on want to be on your site ? only when they believe to benefit from it, its plain business. So why would you expect any company to pay for you clicking on your own site or your Friends clicking on ads which they are in no way interested ? Would you pay a plumber who comes to you home and stands there talking on his cellphone all day? like that they ( the advertisers) are paying you to do a job.

So is it possible to make money from advertising on your space ? yes it is but only when your are really into what your doing and not doing it for the money it brings. That brings me to sincerity to work , a website owners work is his site or a blogger work is his blog.
Let me explain what am trying to convey before starting this blog i spent a decent amount of time talking to my friends , family, neighbors etc. I also spent time trying to figure out the legitimacy of many of the get rich quickies. Now the most important thing is that it should not be all about making money from your site blog etc. Spent time trying to make it as help full to the targeted audience as possible display ads to your hearts content but, let it have content too keep it updated always. Is there a formula to a site ,blog forum or anything that will work ? no there is absolutely no such formula like that. I cant tell you how to make your blog work (i mean both making people like it and it bringing returns) nor can anyone. That is simply because there are no hard and fast rules about it. Always remember that even if it doesn't bring money it should bring satisfaction that you have got your word across that is most important and also try to learn as much as possible when your doing something so that if it fails it will benefit you may be later on in life. Now i close this post by saying it is possible to earn from advertising on any legitimate site or blog.
