Google’s John Mueller once revealed that more weight is given to how many clicks it takes to get from a site’s homepage to the destination page versus the number of slashes in the page’s URL. Page depth is defined as the number of clicks it takes to get to the destination page from the website’s home page. Hence, the higher the page depth, the less likely search engines are to crawl it, especially on larger websites. Googlebot crawls billions of web pages day-in and day-out, so with the limited time to crawl your site, Google tends to prioritize crawling URLs with a lower page depth. That’s why you should always structure your websites such that the critical web pages are only a few clicks away from your home page.
