# Page of Interest Parameter

#### WT.pi

`WT.pi=Page identification` This parameter identifies a page on your site that is critical to evaluating performance. `Page identification` can be any string. When you enable **Page of Interest Unique Visitor Tracking** in the Visitor History dialog of a profile, Webtrends stores the values for the `WT.pi` parameter for each unique visitor in the Visitor History database. You can limit the amount of disk space used to store these values by keeping the strings as short as possible.

As a best practice, you should only identify key pages on your site with this parameter because Webtrends stores a maximum of 20 pages for each unique visitor for each profile.

Use this parameter to create a Page of Interest dimension that can be associated with a measure based on the `WT.vr.piv` Visitor History parameter. For more information, see `WT.vr.piv` on “Visitor Tracking Parameters.”
