| /category/shoes/running/nike-pegasus/ | 4 | 4 | 5 | 9 | 9 | Depth is high for a priority product |
| /blog/technical-seo/internal-links-guide/ | 3 | 3 | 4 | 14 | 6 | Balanced informational content |
| /support/account/billing/invoices/download/ | 5 | 5 | 5 | 4 | 5 | Useful page but structurally deep |
Formula Used
Weighted Structure Depth = (Click Depth × 0.45) + (URL Levels × 0.20) + (Breadcrumb Depth × 0.15) + (Link Support Penalty × 0.10) + (Priority Mismatch Penalty × 0.10) + structural penalties.
Link Support Penalty = max(0, 4 − min(4, Internal Links ÷ 5)). This lowers the penalty when the page receives stronger contextual linking.
Recommended Max Depth is based on page type and page importance. High-priority pages are expected closer to the homepage than low-priority pages.
Overall Score = average of Structural Efficiency Score, Crawl Accessibility Score, and Link Equity Reach Score. Higher values mean a cleaner, more accessible structure.

FAQs
1. What is site structure depth?
It describes how many steps users and crawlers need to reach a page from the homepage or major hub pages. Lower depth usually improves discovery and authority flow.
2. Why does click depth matter for SEO?
Deeper pages often receive less internal equity and slower crawler attention. Important pages that sit too far from strong hubs can underperform in indexing and rankings.
3. Is URL depth the same as click depth?
No. A short URL can still be hard to reach, while a longer URL may remain well linked. This calculator uses both because they signal different structural issues.
4. What counts as a good depth score?
Priority commercial pages usually perform best when reachable within two or three clicks. Supporting or archival pages can sit deeper if strong internal linking still exists.
5. How do internal links affect the result?
More internal links reduce the support penalty and increase the link equity reach score. Relevant contextual links matter more than large blocks of repetitive footer links.
6. Should orphan pages always be fixed?
Yes, in most cases. Orphan pages are difficult for crawlers and users to discover naturally, and they usually miss out on the authority passed through internal links.
7. Can this calculator help with large sites?
Yes. It is useful for ecommerce, publishing, SaaS, and support sites where page templates vary and structural depth can quickly become inconsistent across sections.
8. What should I improve first?
Start with high-importance pages showing excess depth, weak hub access, few internal links, or missing sitemap inclusion. Those fixes usually create the fastest technical SEO gains.
