Final answer:
Pogo-sticking occurs when a user quickly navigates between pages in search results, indicating they did not find what they were looking for.
Step-by-step explanation:
The term that occurs when a user quickly navigates back and forth between pages in search results is pogo-sticking. This behavior is not to be confused with bouncing, which refers to when a visitor lands on a website and leaves without browsing any other pages. Pogo-sticking can indicate that the user did not find the content they were looking for on the initial page they visited and thus kept returning to the search results to try other pages.
