Understanding Internal Link Ratio
How we calculate. Internal link ratio % = (internal ÷ total links) × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Internal Link Ratio case uses internal links 24 and total links 30. Enter the same figures below to reproduce the worked path.
What is Internal Link Ratio?
A structural SEO metric for navigation and content hubs. Extremely low internal linking can weaken crawl paths and topical clustering.
- Count unique hrefs or raw anchors—be consistent
- Exclude #fragments if they are same-page only
- Hub pages often lean more internal
The Formula
Worked Example
Common Use Cases
- Content audits: orphan risk signals
- Template QA: footer/nav vs body links
- Topic clusters: reinforce pillar pages
Pro Tips
- Quality of targets beats raw ratio
- Don’t spam sidebars
- Use descriptive anchors
Limitations: Internal Link Ratio results are educational SEO planning aids—not guarantees of rankings or traffic. Search algorithms and attribution models vary.
FAQ
Is higher always better?
No—useful external citations are fine. Watch for pages with almost no internal paths.
Sitewide chrome links?
Decide whether nav/footer counts; body-only audits are often clearer.
