Free Internal Link Checker

Internal links distribute authority and guide crawlers — but dead anchors and stray nofollows silently waste them. NToolHub's free Internal Link Checker extracts every internal link from your HTML, showing anchor text and href with automated issue flags. Link builders and site auditors use it to squeeze more value from existing pages.

Links pointing to this domain (or relative links) count as internal.
Private by design. This tool runs 100% in your browser — your content is never uploaded to any server.

How to Use the Internal Link Checker

  1. Enter your domain so links can be classified correctly.
  2. Paste the page HTML and click Check Internal Links.
  3. Review the table: fix empty anchors, dead # hrefs and stray nofollow.
  4. Use descriptive anchor text that tells readers (and Google) what the target page is about.

Features

Enter your domain and paste HTML to classify links accurately (relative URLs resolved against your domain), then get a full table of internal links with anchor text, href and flags for empty anchors, dead '#' hrefs and accidental nofollow attributes.

Benefits & Use Cases

Strong internal linking spreads PageRank to deep pages, speeds up indexation of new content, and keeps visitors exploring — directly lifting rankings and engagement on pages that were previously orphaned.

Tips

Use descriptive, varied anchor text (not 'click here'), link deep pages from high-authority pages, and never nofollow your own internal links — you're telling Google not to trust your own site.

Frequently Asked Questions

What counts as an internal link?

Any link pointing to the same domain — including relative links like /about. The tool resolves relative URLs against the domain you enter.

Why is nofollow bad on internal links?

Nofollow tells Google not to pass ranking signals through the link. On your own internal links it just wastes authority you'd otherwise distribute.

How many internal links per page?

There's no hard limit. Link where it helps readers — contextual links within content outperform footer link dumps. Every important page should have several.

What makes good anchor text?

Descriptive text that tells readers what they'll find — e.g. 'technical SEO audit checklist' instead of 'click here'. Vary phrasing naturally across the site.
