Internal Link Checker

Audit internal links from HTML or URL lists, classify link scope, and flag crawl-risk patterns before publishing.

About this tool

Audit internal linking inputs before release so malformed href values, duplicate targets, and weak anchor coverage do not degrade crawl paths and on-site SEO signals.

Internal Link Checker audits the anchor elements on a page to verify that internal links use crawlable href values, avoid unnecessary nofollow attributes, and point to live, indexable destinations. It surfaces the linking patterns that determine how search engines discover and distribute authority across your site.

  • Parses HTML anchor tags or plain URL lists with optional anchor text and rel attributes.
  • Classifies links as internal, external, or non-crawlable and flags unsafe or malformed href values.
  • Highlights duplicate destinations, missing anchor text, and potential orphan URLs from an optional indexable URL inventory.

How to use Internal Link Checker

Provide a page URL or paste its HTML, and the tool extracts every internal link, categorizing them by status, anchor text, and any attributes that affect crawlability. The report highlights empty hrefs, JavaScript-only links, nofollow tags on internal URLs, and links pointing to redirected or error pages.

When this tool is useful

  • Audit page HTML before release to confirm important URLs are linked internally.
  • Check template or navigation changes for nofollow, empty href, and non-crawlable link patterns.
  • Compare page links to your indexable URL inventory to catch potential orphan pages early.

Practical tips

  • Use descriptive anchor text on key internal links so relevance signals remain clear.
  • Avoid adding UTM parameters to internal links unless tracking requirements explicitly demand them.
  • Pair this page-level audit with sitewide crawls for final validation on large sites.

Why people use this tool

Internal links are the primary mechanism through which search engines discover pages and distribute ranking signals within a site. Broken, nofollowed, or JavaScript-dependent internal links create orphan pages that never get indexed and waste the authority your site has earned from external backlinks.

Frequently asked questions

Can I paste HTML from a page template?

Yes. You can paste full HTML snippets with anchor tags, and the checker extracts href, rel, and anchor text for analysis.

Does this internal link checker crawl live pages?

No. It validates the links you provide in-browser. Use this as a pre-publish QA step before running full live crawl audits.

What types of crawl-risk patterns does the checker flag?

It flags links with nofollow attributes on internal pages, links pointing to redirected URLs, links to pages blocked by robots.txt, and excessive query-string variations that can waste crawl budget.

Can I upload a Screaming Frog or Sitebulb export directly?

Yes. The tool accepts CSV and line-separated URL lists, so you can export internal link data from popular crawl tools and paste or upload it directly for analysis.

How does the tool classify internal versus external link scope?

Links are classified by comparing the link's hostname to the source page's hostname. Subdomains are treated as internal by default, but you can configure this behavior for stricter separation.
