Re: Large Log FIles [ In reply to ]
Thanks Alan,
Here is the thing my host told me I recieve 2,000 request (hits) per second. What if I count the amount of images I have on the page and from there divide by the number of request (hits)? How does that sound?

The numbers in ( ) are usally for the last 7 days.  Near the top of your report there is a line that'll tell you.

IP addresses can give you some idea - but some IP addresses are just firewalls or NAT boxes etc that are masking groups of computers from the internet.  Some ISP's give each access its own IP so you may have 1 webpage (1 x html, 9 images) and '10' visits which is just a single person fetching a page.

Unfortunatly a lot of people want 'exact' and can't/won't understand that even when presented with it as 'x' piece of software does it.  Remember the quote - Lies, Damn Lies and Statistics.  Analog reports what it can - it doesn't attempt to 'guess'.  Cookies, sessions help but, as Jason says - you can't change how the web works.  It's a fundamental but it also works very well.

WOW! It seems a little hopeless. Unique IP addresses can't count as visits? I was thinking I can use "Successful requests for pages" as visits. On Analog, what are the numbers in ( )'s ?

There is no way to accurately determine visits or visitors. It doesn't help to take the additional steps (sessions, cookies etc), that just gives you different results, not better results.

This is a fundamental issue in how the web works. There is no solution, only approximations. There isn't even a standard for how to do the approximations. Various groups use different approaches to approximating the results.

All kinds of trouble comes from this. Everyone always wants to know the number of visits/visitors. Since we can't know either of those, some approximation is made and used as if it is true. However, every approach to making an approximation gives different results, so when someone challenges your approximation they will always be able to come up with some "authoritative" source that gives conflicting results, no matter where you got your numbers to begin with.

Dr. Seuss books . . . can be read and enjoyed on several levels. For
example, 'One Fish Two Fish, Red Fish Blue Fish' can be deconstructed
as a searing indictment of the narrow-minded binary counting system.

Re: Large Log FIles [ In reply to ]
Since, request (hits) are not "visits", would it be safe to say that "succesful request for pages" comes close? Would that be safe to tell an advertiser?
