Click Depth

Click depth is the number of clicks it takes to reach a page from the homepage by following internal links. The homepage has a depth of zero, pages linked from it have a depth of one, and so on. Pages buried deep in a site tend to be crawled less often and seen as less important.

How click depth works

Click depth is measured by the shortest path of links, not by the URL. A page at /blog/2024/06/post/ might look deep, but if it is linked from the homepage its click depth is one. Equally, a page with a short URL can sit five clicks deep if the only route to it is through several layers of navigation.

It is closely related to site architecture, the way pages are organised and linked together. A flat structure keeps most pages within a few clicks; a deep one buries them.

Why click depth matters for SEO

  • Crawling: crawlers find pages by following links. Pages many clicks deep may be discovered more slowly and recrawled less often.
  • Importance: Google has said that pages linked from the homepage are generally treated as more important. Deep pages usually receive less link equity flowing through internal links.
  • Users: visitors give up if important content is hard to reach.

A common rule of thumb is to keep important pages within three clicks of the homepage. That is a practical guideline from the SEO community, not a Google rule. On a very large site, four or five clicks may be unavoidable for some pages; what matters is that key pages are easy to reach.

How to measure click depth

  1. Crawl your site with an SEO crawler, starting from the homepage.
  2. Look at the crawl depth column or report, which shows each URL’s depth.
  3. Sort by depth and compare it with traffic or value: important pages at depth five or more are a warning sign.
  4. Look for pages with no depth at all. These are orphan pages with no internal links pointing to them.

How to reduce click depth

  • Link to key categories and money pages from the main navigation or homepage.
  • Use contextual internal linking between related articles and products.
  • Add breadcrumbs so every page links back up through its category path.
  • Fix deep pagination by showing more items per page or adding links to subcategories.
  • Create hub pages, such as a pillar page, that link out to a whole topic.
  • Use an HTML sitemap or “popular pages” sections for large sites.

Common mistakes

  • Relying on an XML sitemap to make up for poor linking. Sitemaps aid discovery but do not pass internal link value.
  • Stuffing hundreds of links into the footer to flatten the site, which makes navigation less useful.
  • Confusing URL folder depth with click depth.
  • Burying new products or articles behind long “load more” buttons that crawlers may not trigger.

Key Takeaways

  • Click depth is how many clicks a page sits from the homepage.
  • Deep pages are usually crawled less often and seen as less important.
  • Keeping key pages within about three clicks is a useful guideline, not a rule.
  • Internal links, breadcrumbs and hub pages reduce click depth.
  • Click depth is about links, not URL structure.
