Link Depth †

Link Depth is defined as an index for indicating the extent to which a user has moved deeper into the Web following links from search engine result pages (SERP).

Link Depth is defined as follows：

• Link Depth to a viewed page reached through a link from a search engine Result Page (SERP) = 1.
• Link Depth for a page reached through a link from a page with a Link Depth of 1 = 2; Depth increases by 1 for each link followed.
• If the user moves back using the Back button on the browser, the Link Depth is -1 of the previous page; if the Next button is used, the Link Depth is +1 of the previous one.
• If the user moves to a bookmarked page or a page shown in the browser history, the Link Depth is the same as the original bookmarked page or the original page shown in the history

Result †

In the trip task, most of the participants explored more deeply on the Web than in the report task. This result reflects the relationship between tasks and the physical characteristics of the Web.
