Internal Link Audit: The Complete 2026 Audit Checklist

Before starting the audit, ensure you have:

• A full crawl of your website (Screaming Frog, Sitebulb, or similar)
• Google Search Console access
• Server log access (recommended but optional)
• A list of all pages in your XML sitemap

Run the crawl from your homepage with default settings. Ensure the crawler follows all internal links and does not exceed a reasonable depth (10+ clicks).

Orphan pages are the highest priority issue in any internal link audit. Use the crawl comparison method:

1. Export all URLs discovered by your crawler (internal link graph)
2. Export all URLs in your XML sitemap
3. Subtract the crawl URLs from the sitemap URLs
4. The remainder are orphan pages

For each orphan page, decide: keep (add internal links), merge (301 redirect to a related page), or delete (return 410).

Map how equity flows from your highest authority pages. Identify:

• Pages with zero inbound internal links (orphans, covered above)
• Pages receiving more than 50% of their inbound links from navigation/footer
• Pages with more than 100 outbound links (equity dilution)
• Pages with fewer than 3 internal links pointing to them
• The average number of clicks from the homepage to each page

Prioritize pages that are 4+ clicks from the homepage. These pages often suffer from equity starvation and need direct links from higher tier pages.

Extract all internal anchor text from your crawl data. Look for:

• Generic anchors ("click here", "read more", "learn more")
• Over-optimized exact match patterns (same anchor text used repeatedly)
• Broken links (404s) that produce dead anchor text
• Missing alt text on image-based links
• Anchor text that does not match the target page content

Create a fix list sorted by the authority of the source page. Fixing anchor text on a high authority page has more impact than fixing it on a low authority page.

Check that link attributes are applied intentionally:

• Nofollow should be used on login pages, privacy policies, tag pages, and user-generated content
• Sponsored should be used on affiliate and paid links
• UGC should be used on forum posts, comments, and user submissions
• Follow (no attribute) should be the default for all editorial links

Misapplied attributes can accidentally block equity flow to important pages.

Ensure your internal linking reflects your intended site structure:

• Verify that pillar pages link to all cluster pages
• Confirm that cluster pages link back to pillar pages
• Check that silo pages rarely link outside their silo
• Validate breadcrumb schema implementation
• Confirm URL structure matches the logical hierarchy

Link rot occurs when internal links break over time. Identify:

• 404 links (pages that no longer exist)
• 301 redirect chains (links that redirect multiple times)
• Links to pages that have been merged or moved without redirects
• Broken anchor links (hash links that no longer match a heading)

Fix all broken links and replace redirect chains with direct links.

Document all findings in a structured report. Track:

• Total orphan pages found and fixed
• Pages with improved anchor text
• Equity distribution improvements
• Average click depth reduction

Set up monthly automated checks for new orphan pages and broken links.

• [ ] Crawl full site and compare against sitemap to find orphans
• [ ] Fix all orphan pages (link, merge, or delete)
• [ ] Identify pages with zero inbound internal links
• [ ] Check pages exceeding 100 outbound links
• [ ] Audit anchor text for generic or over-optimized patterns
• [ ] Verify link attributes (nofollow, sponsored, ugc) are intentional
• [ ] Validate pillar-cluster linking structure
• [ ] Check for broken links and redirect chains
• [ ] Confirm breadcrumb schema markup is present
• [ ] Document findings and set up automated monitoring
