How to Audit Your Website's Internal Links for Better SEO
Learn how to audit internal links on your website to improve SEO, distribute page authority, and help visitors find your best content faster.
Internal links are one of the most underrated SEO tools you have. They cost nothing, take minutes to add, and can dramatically improve how Google crawls and ranks your pages. Yet most websites have broken internal linking strategies — or no strategy at all.
An internal link is any link from one page on your site to another page on the same site. Unlike backlinks (which come from other websites), internal links are entirely within your control. They tell search engines which pages matter most, how your content relates, and where to send link authority.
In this guide, you'll learn how to audit your internal links, spot common problems, and fix them to boost your rankings and user experience.
Why Internal Links Matter for SEO
Google's crawlers follow links to discover pages. If a page has no internal links pointing to it, Google might never find it — or might assume it's not important. Here's what proper internal linking does:
- Distributes page authority — Links pass "link equity" from high-authority pages to others
- Helps crawlers discover content — Every page should be reachable within 3 clicks from your homepage
- Establishes topical relationships — Linking related content signals to Google what your site is about
- Reduces bounce rate — Visitors find more relevant content and stay longer
- Improves indexation — Orphan pages (with no internal links) often don't get indexed
Sites with strong internal linking structures typically see 20–40% improvements in organic traffic after fixing issues. It's low-hanging fruit that most competitors ignore.
Step 1: Find Your Orphan Pages
Orphan pages are pages with zero internal links pointing to them. They exist on your site but are essentially invisible to both users and search engines.
To find orphan pages:
- Get a list of all your URLs — Check your sitemap or use a crawling tool
- Compare against internal link data — Any URL not linked from another page is orphaned
- Prioritize by importance — Your best content shouldn't be orphaned
Common orphan page culprits:
- Old blog posts that were never linked from newer content
- Landing pages created for ads but not integrated into navigation
- Category or tag pages with no contextual links
- Product pages removed from navigation but still live
Fix: Add contextual links from relevant pages, include in navigation menus, or link from your homepage or pillar content.
Step 2: Check Your Click Depth
Click depth measures how many clicks it takes to reach a page from your homepage. Pages buried deep in your site (4+ clicks) get less crawl attention and less authority.
Ideal click depth structure:
- 1 click — Your most important pages (services, main categories, key landing pages)
- 2 clicks — Important subpages and recent blog posts
- 3 clicks — Older content, specific product pages, archive pages
- 4+ clicks — Should be minimal; consider restructuring
If your best content is 5 clicks deep, Google treats it as less important than it should be. Flatten your structure by:
- Adding links to important pages in your main navigation
- Creating hub pages that link to related content
- Adding "featured" or "popular" sections on key pages
- Using breadcrumbs to create upward linking paths
Step 3: Analyze Anchor Text Distribution
Anchor text is the clickable text in a link. Google uses it to understand what the linked page is about. If all your internal links use generic text like "click here" or "read more," you're wasting SEO signals.
Good anchor text practices:
| Instead of... | Use... |
|---|---|
| Click here | Learn how to improve page speed |
| Read more | Our complete guide to Core Web Vitals |
| This article | How to check if your site is mobile-friendly |
What to audit:
- Do your anchor texts describe the linked page's content?
- Are you using varied (but relevant) anchor text for the same page?
- Are you avoiding over-optimization (exact-match keywords every time)?
A natural anchor text profile mixes branded terms, partial keywords, and descriptive phrases. Don't force exact-match keywords into every link — it looks spammy.
Step 4: Identify Broken Internal Links
Broken internal links hurt both UX and SEO. Visitors hit dead ends, and crawlers waste resources on 404s. Common causes:
- Pages that were deleted without updating links
- URL changes without proper redirects
- Typos in manually-added links
- CMS migrations that broke URL structures
How to find them:
- Run a site crawl that checks response codes
- Look for any internal link returning 404, 500, or redirect chains
- Check Google Search Console's "Crawl errors" report
How to fix them:
- Update links to point to the correct URL
- Set up 301 redirects from old URLs to new ones
- Remove links to permanently deleted content
SiteScore automatically detects broken links during your website audit, showing you exactly which pages have dead links and what URLs they're trying to reach.
Step 5: Review Link Distribution
Not all pages should have equal numbers of internal links. Your most important pages should receive the most internal link attention.
Audit your link distribution:
- List your top 10 most important pages (homepage, key services, best content)
- Count how many internal links point to each
- Compare against less important pages
If a random old blog post has more internal links than your main service page, you have a distribution problem. Fix it by:
- Adding links to important pages from high-traffic content
- Featuring key pages in sidebars, footers, or "related" sections
- Creating pillar content that naturally links to priority pages
- Removing excessive links to low-value pages
Step 6: Check for Redirect Chains in Internal Links
A redirect chain happens when a link points to URL A, which redirects to URL B, which redirects to URL C. Each hop loses a small amount of link equity and slows down crawling.
Example of a redirect chain:
/old-page → /newer-page → /newest-page
When linking internally, always link to the final destination URL. Update old internal links whenever you set up redirects.
Signs you have redirect chain issues:
- You've changed URL structures multiple times
- You use plugins that automatically redirect old URLs
- Your CMS creates multiple URL versions (with/without trailing slashes, www vs non-www)
Fix: Audit internal links and update them to point directly to canonical URLs.
Step 7: Evaluate Contextual vs Navigational Links
There are two types of internal links:
Navigational links — In your header, footer, sidebar, or menu. They're sitewide and pass less value than contextual links.
Contextual links — Embedded naturally within your content. They pass more value because they're surrounded by relevant text and are clearly intentional.
A healthy internal linking profile has both, but contextual links are where the real SEO power lives. If your only internal links are in navigation, you're missing opportunities.
Add contextual links by:
- Mentioning and linking to related posts within blog content
- Linking to service pages when you naturally mention a topic
- Creating "related resources" sections within content
- Using in-text links when a previous post explains a concept in more detail
