Pages with high click depth — buried four, five, or more clicks from the homepage — tend to get crawled less frequently and receive less internal link equity, both of which can suppress their ranking potential regardless of how good the content itself is. This is a common, easy-to-miss problem on large sites with deep category hierarchies or a glossary/resource section that isn't well linked from higher-traffic pages. Reducing click depth doesn't require flattening a site's entire structure; it usually just means adding more internal links from high-authority pages (the homepage, popular blog posts, navigation menus) directly to important deep pages, rather than relying purely on the default hierarchical path to reach them.
Example
A glossary with 190 terms is technically reachable but sits five clicks deep from the homepage; adding a footer link and cross-links from relevant blog posts drops the average click depth to two.
