I am creating a click counter using a php script so i can log the amount of clicks to a certain url. I need to know this so I can bill my advertisiers.
However, I am aware that one of the main problems with cost per click campaigns is fraud.
I intend to use the $_SERVER['REMOTE_ADDR'] to get the ip address of the 'clicker' & use this to separate unique clicks.
- Is this an acceptable method?
- How can IP addresses be faked?
- What other methods of fraud prevention can i use?
