In Search Engine Optimization: Comparison of Link Building and Social Sharing (Sonya Zhang & Neal Cabage, 2016) I found a troubling id est relation:
Using well-structured pages including sections and categories, self-documenting semantic URLs, well-selected internal linking and keywords, and effective navigation can get a user to any page of the site with fewer clicks, i.e., high click-through rates (CTRs).
This point is not further developed in the rest of the paper, and my question is: In which way the fact that a page is accessible in few clicks is equivalent to the page having a high CTR ?
