Our group have been using Analog since Apr. 2002 to see how often
people
access our website. In our reports, the average monthly #reqs under
"OS unknown" in "Operating System Report" is as following:
Year #reqs
------------------------
2002 1600
2003 2400
2004 4500
2005 8300
2006 19000
You can see that the number is increasing each year. It seems not
reasonable to count those #reqs as people "actually" using our
websites. How can I determine if these OS unknown includes robots
or search engines?
You can find a fairly comprehensive list of known Robots, nicely confgured
as a ROBOTINCLUDE list at:
http://www.wadsack.com/robot-list.html
How can I decrease the OS unknown numbers?
Browser strings usually indicate the OS that the browser is running on. If
you do a full Browser Report (BROWSERREP ON) you should be able to pick out
browsers that don't specify an OS. You can make this easier by specifying
commands like
BROWREPEXCLUDE *Windows*
etc to exclude the known ones.
Once you get a list of Browser Strings that aren't recognized as Robots
(with ROBOTINCUDE commands) and that don't include OS strings, you can use
BROWALIAS commands to assign an Operating System.
Here's an example that changes a Browser from "OS Unknown" to "Windows XP":
BROWALIAS Microsoft-WebDAV-MiniRedir/5.1.2600
"Microsoft-WebDAV-MiniRedir/5.1.2600 (Windows NT 5.1)"
