Webtrends Analytics 9 Adminstration Guide, November 2012
If your web site content is dynamically generated and you do not use SmartSource Data Collector (SDC) or Webtrends Analytics 9, create a URL Rebuilding definition to specify in Webtrendswhich parameters in URLs identify pages on your site.
If your web site content is dynamically generated and you do not use SmartSource Data Collector (SDC) or Webtrends Analytics 9, specify in Webtrendswhich parameters in URLs identify pages on your site. You specify these parameters by creating a URL Rebuilding definition. The URL Rebuilding definition specifies not only the parameters that matter for identifying pages, but also the parameters in the URL that Webtrends should ignore during processing. For example, Webtrendsshould ignore sessionid or visitorid parameters because these unique values make every URL look like a unique page during processing. Also, if your web site has an internal search engine or a knowledge base, exclude the query strings for search engines and knowledge base-related parameters that can quickly fill up the table with unique URLs.
As a best practice, if you have a site with many products, the URL Rebuilding definition that you use for your SmartView profile should only include the parameters for top-level product categories, rather than the individual products. To report on products extensively, you should create a separate standard profile that uses a different URL Rebuilding definition.
Without a properly configured URL Rebuilding definition, SmartView is unable to differentiate links on your site's web pages, resulting in inaccurate link data.
