Glossary Authentication Technique that limits access to Internet or intranet resources to those visitors who identify themselves by entering a username and password. Average Time to Serve Documents Average amount of time it took to serve each document during the specified time interval. The time to serve spans from the time your server gets a page request until it transmits all the data. Average Time to Serve Dynamic Pages and Forms Average amount of time it took to serve each dynamic page or form during the specified time interval. The time to serve spans from the time your server gets a page request until it transmits all the data. Bandwidth Measure (in kilobytes of data transferred) of the traffic on a site. Browser A program used to locate and view Web pages. These include Netscape, Mosaic, Microsoft Internet Explorer, and others. Client The browser used by a visitor to a Web site. Client Errors An error occurring due to an invalid request by the visitor's browser. Client errors are in the 400-range. See the "Return Code" glossary entry for more information. Company Database The database installed and used by WebTrends to look up the company name, city, state, and country corresponding to a specific domain name. Cookies Files containing information about Web site visitors. This information can include the visitor's username, preferences, etc. The information is provided by visitors during their first visit to a Web site. The server records this information in a text file and stores it on the visitor's hard drive. At the beginning of later visits, the server looks for a cookie and configures itself based on the information provided. Documents Pages that were defined as "documents" in Options. Typically, pages are defined as a document if the content is static, such as complete HTML pages. However, you can define dynamic pages and forms as documents if you choose. Domain Name The text name corresponding to the numeric IP address of a computer on the Internet. For example, www.webtrends.com is a domain name. Domain Name Lookup The process of converting a numeric IP address into a text name (for example, 204.245.240.194 is converted to www.webtrends.com). Dynamic Pages and Forms Pages that are generated dynamically based on values selected by a visitor. They are generated with variables, and do not exist anywhere in a static, predictable form. WebTrends counts any file with an HTTP Post command or a Get command with a "?" as a dynamic page/form. Entry File The first file the visitor downloaded when entering your Web site. Entry Page The first page a visitor viewed when entering your Web site. If a visit consists only of hits to non-page files, that visit has no entry page. This can cause the total number of entry pages to be less than the total number of visits. Exit Page The last page a visitor viewed before leaving your Web site. If a visit consists only of hits to non-page files, that visit has no exit page. This can cause the total number of exit pages to be less than the total number of visits. File Type Identifies types of files by their file extension. For example, a file named graphic.gif is identified as type 'gif.' Filters A means of narrowing the scope of a report by specifying ranges or types of data to include or exclude. Forms Scripted pages which pass variables back to the server. These pages are used to gather information from visitors. WebTrends counts any file with an HTTP Post command as a form. HTML Hypertext Markup Language. It is the programming language for static Web pages. It usually includes hypertext links between related objects and documents. HTTP Hypertext Transfer Protocol. It is a standard method of transferring data between a Web server and a Web browser. Hit A single action on the Web server as it appears in the log file. A visitor downloading a single file is logged as a single hit, while a visitor requesting a Web page including two images registers as three hits on the server; one hit is the request for the .html page, and two additional hits are requests for the downloaded image files. While the volume of hits is an indicator of Web server traffic, it is not an accurate reflection of how many pages are being looked at. Home Page The main or introductory page of a Web site. The home page provides visitors with an overview and links to the rest of the site. It often contains or links to a table of contents. Home Page URL The URL for the home page of the site analyzed in the report. IP Address Internet Protocol Address. It is a series of four one- to three-digit numbers separated by periods. It is used to identify a computer connected to the Internet. For example, 212.6.125.76 is an IP address. Log File A file created by a Web or proxy server which contains information about the server's activity. Median Visit Length Median of non-zero length visits in the log. Half the visit lengths are longer than the median, and half are shorter. This number is often closer to the "typical" visit length than the average visit length. Numbers that are wildly atypical can skew the average, but will not skew the median so much. Page Any document, dynamic page, or form. Documents are user-defined in Options, but typically include all static content, such as complete html pages. Dynamic pages are created with variables and do not exist anywhere in a static form. Forms are scripted pages which get information from a visitor and pass it back to the server. Path Through Site The sequence of pages a visitor views, from the entry page to the exit page. Paths from Start With the exception of the starting page, the path a visitor takes to a destination or exit page. Platform Refers to the operating system, such as Linux or Windows 98. Protocol An established method of transmitting data from one computer to another. Referrer URL of a Web page that refers visitors to your site. Return Code The return status of the request which specifies whether the transfer was successful and why. Possible "Success" codes are: 200 = Success: OK 201 = Success: Created 202 = Success: Accepted 203 = Success: Partial Information 204 = Success: No Response 300 = Success: Redirected 301 = Success: Moved 302 = Success: Found 303 = Success: New Method 304 = Success: Not Modified Possible "Failed" codes are: 400 = Failed: Bad Request 401 = Failed: Unauthorized 402 = Failed: Payment Required 403 = Failed: Forbidden 404 = Failed: Not Found 500 = Failed: Internal Error 501 = Failed: Not Implemented 502 = Failed: Overloaded Temporarily 503 = Failed: Gateway Timeout Returning Visitors Visitors who already had a cookie from your site before they visited. Server A computer that hosts information available to anyone accessing the Internet or an internal intranet. Server Error An error occurring on the server. Web server errors have codes in the 500 range. Single Access Page A page on your Web site that visitors open, then exit from, without viewing any other page. To qualify the visit must be to a page with a valid document type. If the visit is to a document with a different type (such as a graphic or sound file), the file does not count as a single access page, and the visit is not included in the total. Such visits are often the result of other sites referencing a specific downloadable file or graphic on your site. In these cases, a visit may have a single hit to a non-document type file, and will not be counted in the percentage calculations. Spider An automated program which searches the internet. Suffix (Domain Name) See Top-Level Domain. Time Interval A one-year report displays monthly time increments. A one-quarter report displays weekly time increments. A one-month report or a one-week report displays daily time increments. A daily report displays hourly time increments. An hour-long interval marked 12:00, for example, includes all activity between 12:00 and 12:59. Top-Level Domain The suffix of a domain name is the top-level domain. A top-level domain is generic (.com, edu, .museum, .name, etc) or a country code (.uk, .de, .jp, .us, etc.). The top-level domain can be used to identify the type of web site. The following is a partial list of how this report categorizes top-level domains: ARPANET: .arpa Commercial: .com .co .com.[country code] .co.[country code] .firm.co .firm.ve .ltd.uk Education: .edu .edu.[country-code] .ed.[country code] .ac.[country code] .school.[country code] .k12.[country code] .re.kr .sch.uk .edunet.tn International: .int .int.co .int.ve .intl.tn Government: .gov .gov.[country code] .gove.[country code] .go.[country code] Military: .mil .mil.[country code] Network: .net .ad.jp .ne.kr .net.[country code] Organization: .org .or .org.[country code] .or.[country code] URL Uniform Resource Locator. It is a means of identifying an exact location on the Internet. For example, http://www.webtrends.com/html/info/default.htm is the URL which defines the location of the page Default.htm in the /html/info/ directory on the NetIQ Corporation Web site. As the previous example shows, a URL is comprised of four parts: Protocol Type (HTTP), Machine Name (webtrends.com), Directory Path (/html/info/), and File Name (default.htm). Unique Visitors Individuals who visited your site during the report period. If someone visits more than once, they are counted only the first time they visit. Visit All the activity of one visitor to a Web site. If a visitor is idle longer than the idle-time limit, WebTrends assumes the visit ended. If the visitor continues to browse your site after they reach the idle-time limit, a new visit is counted. The default idle-time limit is thirty minutes, but can be changed in Options. Visit Duration (Minutes) Number of minutes your Web site was viewed by a visitor. Visitor-Minutes Total number of minutes your site was viewed by all visitors during the specified report period.
