I just want some suggestions, not theory. Please, don't start rambling about this and that and why and not and blah blah blah. I respect all of you, but you people do tend to go on random tangents that just gives me a headache.
Having said that, can you please tell me what YOU use to count your unique visitors, and let's leave it at that. Please, no loooooooong theories. Just tell me what you use. At the end, I'll take the most popular and use that.
Thank you.
Your best bet is just to choose a stats program, then use it for all of your reporting. It will still be only a "best guess", but at least it will be a consistent best guess.
Unique Visitors - These are the total number of visits by a unique IP address. This can be a bit misleading because dial-up visitors get a new IP each time they log on so you can have the same person visit different times and give a unique hit.
As I said before, any stats program that relies on server logs is only going to give you a "best guess".
Then you have to add in a certain percent that are viewing your site from places like AOL, which caches their own version of the web and serves requests from that, which means the only count you will get is the AOL proxy picking up your pages once. That number can represent 25-30% of your total.
Any unique type visitor stat always has to take factors like this into account, but they do give a decent idea.
Personally I do the following: I cound sessions, so same guy visiting in two different weeks counts as 2, I use IP+USER_AGENT to differentiate, and I tiem sessions out at 60 minutes. So if two folks brwose form the same IP usign the same user agent but more then 60 minutes apart I correctly detect them as two visitors. If one guy browses, takes a 3 hour break and then browses some more, IO falsly identify that as 2 visits (that's my inaccuracy). In tests I foudn that setting the timeout to 24 hours doesn't cahnge teh visitor count much. This shows me my measure is pretty good, and the inaccuracies introduced from folks taking long breaks in their browsing is minimal.

I have a little counter on my home page that says "You are visitor number N,NNN".
I think people are not paying attention to the original question. I need to know the unique number of visitors for my ENTIRE site, not just my front page. I have that. I use SiteMeter, and it works great, but of course not everyone who visits one of my pages goes to my home page, thus they don't count. I need to count ALL of my unique visitors, and since I have over 1,200 unique content pages, as well as about 3,000 other pages (with pictures), I don't think putting SiteMeter codes on each one would be viable.
