What is the optimal click depth of a page?

The optimal click depth for a page is generally considered to be less than 4 clicks from the homepage. This ensures that important content is easily accessible to both users and search engine crawlers. Pages buried deeper in the site structure may be less likely to be discovered and indexed, potentially impacting their search visibility. While some pages might naturally require more clicks due to their niche content or extensive site architecture, a shallow click depth is a best practice for most websites to improve user experience and SEO. "Depends on the page" is too vague for an optimal recommendation, and "More than 4" indicates a potentially problematic site structure.
