Managing Visitor History Data

The profile's Visitor History database maintains a history of unique visitor activity over time. You can optimize the performance of profiles that use Visitor History by enabling visitor history trimming and configuring trimming settings to retain the visitor data most valuable to your business.

You can qualify the visitors to trim based on their number of visits, lifetime value, visit recency, and purchase recency. Keep in mind that if trimming is not enabled, the memory required to process a Visitor History-enabled profile may not be sufficient, which prevents Webtrendsfrom analyzing the profile.

Note: If you want to track new visitor statistics, be careful how you trim. When visitors who are deleted from the visitor history database return to your site, Webtrends identifies them as new visitors because there is no history of them.

  5. In the Minimum number of visitor to store... text box, specify the number of visitors to store before any visitors are removed from the database.
  6. In the Maximum number of visitor to store... text box, specify how many visitors to store at most in the visitor history database.
  7. Under Primary Trimming Criteria, specify the criteria to use for removing visitors from the database once the minimum trimming limits are met.
