I have my own tracking system I programmed myself on my website but it doesn't currently calculate unique hits and I want to program it to do this ASAP. How are unique hits normally calculated, for example is it unique per 24 hours, per month, per year, or forever? And is uniqueness based on cookies and/or IP? This will help me program it to calculate unique hits like they normally would be. Thank you
I also think it's the one IP during 24 hours. But if you are programming it you may set it as you see fit according to your needs.
