I created a report that begins with Categories, but it's showing sites with many categories.
Google.com is showing many categories.
Using the "Web browsing per site" shows sites with more than 4 categories per site, sometimes more than 20.
Site reports that include users, show many categories.
Any report based on site will show many categories, especially if it's a generic site, or hosting site. This is because modern sites now can contain many sub-domains with their own categories.
NOTE: Most search related sites such as google.com, yahoo.com, bing.com , or baidu.com will show this symptom.
In one case, one customer created a report as per the instructions below.
The above report showed Google.com as containing many categories, but drilling down to individual URLS we discovered that each URL off of google.com was properly rated with up to 4 categories.
If you are using Bluecoat Webfilter, URLs will show a maximum of four categories, but sites can show more. For more information on how Bluecoat Web Filter/Webpulse works at categorizing sites please see 000010005 .
