Glossary Terms

A bounce occurs when a visitor exits a page without visiting any other page on the site.
The quantity of network bandwidth used by the files requested during the selected date range.
A successful request to your web server from a visitor's browser for any type of file, whether an image, HTML page, or any other type. A single web page can cause many hits - one for each image included on the page, etc.
A request from a visitor's browser for a displayable web page, generally an HTML file. Images and other embedded content, such as style sheets and javascript, are not considered to be page views.
An external URL that brought traffic to your site.
A series of clicks on your site by an individual visitor during a specific period of time. As session is initiated when the visitor arrives at your site, and it ends when the browser is closed or there is a period of inactivity.

UTM vs. Standard Session Tracking

When initially setting up a site for Urchin statistics, you have a choice on the method you wish Urchin to use when tracking visitors. With standard session tracking, Urchin uses the visitor's IP address, browser and platform (e.g. Windows 2000/Internet Explorer 6.0), and a 30 minute session timeout. Standard session tracking requires no site modifications and is available for all domains. However, it is not as accurate as UTM tracking and will include robot traffic in session analysis.

UTM (Urchin Traffic Monitor) tracking utilizes javascript and cookies to track visitors. It is the most accurate tracking method and will also filter out robot traffic from session analysis. UTM also enables additional reporting on unique visitors and sessions plus visitor screen resolutions, colors, language, and more. UTM tracking does require you to modify all pages on your site and is only available for sites hosted by CWS on a domain (e.g.,

Date Range Tool

date range selectorBy default, reports are generated using data from the last 7 days. The reporting period can be changed to a single day, week, month, year, or any arbitrary date range. To view a specific day, month, or year simply click the day, month, or year of interest. To view a specific week, click the arrow to the left of the week you wish to analyze. To specify a date range, click the "Enter Range" link and select the start and end dates of your range.

Sorting Results

On most reports, you may sort by any field or collumn displayed in a table. To change the sort order, simply click one of the small up or down arrow icons next to the field you wish to sort by.

Using Filters

You may optionally apply a filter on the first column of any report that generates a sorted list of entries. Simply type the text you wish to filter, then click the plus button to include only entries matching your text. Alternatively you may click the minus button to exclude all entries matching your text. You may also use the special characters '^' and '$' in your filter text. '^' matches the beginning of an entry, while '$' matches the end of an entry. See the following examples:

Filter text Include result Exclude result
cws Only entries containing "cws" will be shown Entries containing "cws" will be excluded
^/cws Only entries starting with "/cws" will be shown Entries starting with "/cws" will be excluded
html$ Only entries ending with "html" will be shown Entries ending with "html" will be excluded

Printing Reports

A print-friendly view of any report can be generated by clicking the printer icon in the top-right of any report. The print-friendly version will open in a new window.

To quickly print an entire set of reports, click one of the "Print All with Defaults" links in the reports navigation menu. All reports in the section will be generated in a single window using the current date range and default parameters. It is not possible to customize this mass report using filters, sorting, or drilldowns. Generate each report individually if customization is desired.

Exporting Reports

Reports can be exported to Microsoft Word, Excel, and tab separated text formats. To export, simply click on the icon of the desired format. Note that the Word and Excel files do not embed any images, but rather link to the Urchin reporting website. To make the Word report more suitable for viewing off-line, you can manually embed the linked images in a Microsoft Word document using the following steps:

  1. Open the Word document report.
  2. Navigate to Edit->Links in the Word menu. This will bring up a Links dialog box.
  3. Highlight all the listed links in the window and click the Break Link button.
  4. Navigate to File->SaveAs and enter the desired File name, with Save as type of Word Document (*.doc)
  5. The saved document will contain all the required images and should load properly in Word regardless of whether the computer has access to the internet or not.


Note that the above method does not work in Microsoft Excel. There is currently no known workaround for embedding the external links in Excel reports.

UTM Setup

If you requested to use the optional UTM session tracking for your statistics reports, then you must modify all pages on your site that you wish to be included in Urchin's session statistics. Include the following 3 lines in all your html pages (either inside the <head> or <body> of your pages). If your site has a common header file included in all your pages, then you should only need to modify that included file.

<!-- Start Urchin Trafic Monitor code -->
<script type="text/javascript" src="/cw_tools/stats/__utm.js"></script>
<!-- End Urchin Traffic Monitor code -->

Below is an example of a webpage properly modified to use UTM.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="" xml:lang="en" lang="en">
<title>Page Title</title>
<link rel="stylesheet" href="style.css" type="text/css" />

<!-- Start Urchin Trafic Monitor code -->
<script type="text/javascript" src="/cw_tools/stats/__utm.js"></script>
<!-- End Urchin Traffic Monitor code -->

All I'm seeing is "Execution of urchin.cgi timed out." What happened?!
This error condition will sometimes occur when generating reports over a large date-range for sites that see a large amount of traffic. This is due to the archiving mechanism that is used on data that is more than 2 months old. When requesting older data, it takes extra time for Urchin to retrieve and prepare it for reporting. Once prepared, the data is retained for a short while (cached) so that subsequent requests will be much faster. The workaround is simple: refreshing the page in your browser will instruct Urchin to continue processing where it left off, and will usually provide enough time to finish generating larger reports. If the report still fails to complete before the timeout, it may be necessary to shorten the date range of your requested report.
Why are Page Views higher than Downloads for some Adobe Acrobat (PDF) files?
Requested Pages reports may report higher numbers for PDFs than the Downloads report. Some web browsers make multiple requests to a multi-page PDF for a single visitor. This counts as 1 download in the Downloads report, but multiple requests in the Requested Pages report. This is explained in more detail at the official Urchin help site.
The old WebTrends reports showed some useful information. Which Urchin report can show me the same or similar information?
Most WebTrends reports have an equivalent or similar Urchin counterpart. Please see the WebTrends to Urchin report equivalency table.
