Click depth refers to the minimum number of clicks needed to reach a specific page from a website's homepage. The shallower a page's click depth, the fewer actions users need to reach the information they want. Google Search Central's documentation on links (as of December 2025) recommends linking to important pages from at least one other page on the site.
Click depth also relates to crawlability. According to Google's SEO Starter Guide (as of December 2025), Google mainly finds pages by following links from pages it has already crawled.
With a short URL, users can move to the redirect destination in a single click even when it is a page deep in the site's hierarchy. Designing the dashboard so that each link's detail page can be reached within 2 clicks makes the admin screen easier to use. Combined with a well-designed sitemap, even a service with tens of thousands of links can keep click depth shallow.
As an implementation consideration, the design of breadcrumbs and global navigation affects click depth. As the number of pages grows, review the site structure regularly and check whether orphan pages (pages not linked from anywhere) have appeared.
