|Log File Explanation|
Why they are not accurate.
I am working on a presentation to some high level executives at my company. I need to articulate in a non technical way, how and why log files are not as accurate as Page Tagging (Java Script).
Has anyone seen a written example of this? Can anyone help me with their own way of pitching this?
It's all nonsense. Period.
Log files, report, accurately, requests to the http server. And that is ALL.
In simple terms, most companies use a router between their LAN and the Internet. So while every work station in the company has its own IP address, this IP address is local. To the Internet, all stations go through a single router with its own, single IP address, presenting to destination web sites requests (if they get that far and don't get handled by ISP caches along the way) of requests made by a single IP address, which many misleading packages reveal as a single user.
With complex cookies you can do some tracking of run-of-the-mill users, but technicaly savvy users may disable cookies or even delete them during a session, so again results are not to be relied upon.
The issue isn't whether log files are or aren't more accurate than page tagging. Log files and page tagging measure different things. Simply put, log files measure activity as seen by the web server, whereas page tagging measures activity as seen by the web client (browser/UI).
What I would do (have done) in such a situation is to determine what my clients needs are, and provide them with the solution that best meets their needs.
