Word: Pogo Sticking

Definition: A user navigates to a page deeper in a site's hierarchy, only to immediately navigate back to the page in which she came from -- typically happening multiple times in a row.

Thoughts: Pogo sticking tends to occur because of usability problems like misleading links or omitted information. This increased interaction, providing no value to the user, can be extremely costly to a site and can result in decreased engagement over time.  This is different from a "bounce rate" because it happens within the site itself. This behavior pattern likely demonstrates that users are having difficulty finding the content they are looking for.

Question: Can you think of a time that it may be useful to have users bounce back and forth from page to page or should such patterns simply be avoided?
