Internal Link Checker

A while back I pulled the internal link map for a client’s blog and found their best-converting service page the one carrying their highest-margin keyword had exactly three internal links pointing to it. Meanwhile, a one-off announcement post from two years earlier had over 40. Nothing was broken; every link resolved fine. But the site was telling Google which page mattered, and it wasn’t the one generating revenue. We rebalanced anchors across twelve related posts, and within six weeks that service page moved from position 14 to position 6. That’s not a broken-link problem; it’s a structure problem, and it’s exactly what this tool is built to expose.

What This Free Internal Link Checker Tool Does

This tool crawls a site and maps how its pages link to each other not whether individual links are dead, but how link equity and crawl attention are actually distributed. It counts how many internal links point to each page, flags pages with few or zero internal links (orphan pages), measures how many clicks deep a page sits from the homepage, and shows the anchor text being used to reach it.

An internal links checker online like this one differs from a broken-link scanner. Broken-link tools catch dead URLs; this one catch pages that are technically fine but structurally invisible, buried too deep, or linked with anchor text that tells search engines nothing useful.

Where This Internal Link Checker Tool Gets Used

• Orphan page audits: finding pages with no internal links pointing to them at all, which makes them harder for both crawlers and users to find
• Crawl depth checks: identifying pages sitting five or six clicks from the homepage, which often get crawled less frequently
• Anchor text review: catching repetitive or vague anchors like “click here” that waste an opportunity to reinforce topical relevance
• Cornerstone content planning: confirming your priority pages actually receive more internal links than your lower-value ones
• Post-migration checks: verifying internal links survived a redesign or CMS migration instead of pointing to old, redirected URLs

How to Use the Online Internal Link Checker

1. Enter the domain or starting URL you want to map.
2. The tool crawls the site and builds a map of internal links between pages.
3. Review the report: link counts per page, orphan pages, crawl depth, and anchor text used.
4. Prioritize fixes usually starting with orphan pages and your highest-value pages that are under-linked.

Features

Where This Tool Has Limits

This tool maps links it can actually crawl, so pages blocked by robots.txt, gated behind a login, or built with client-side rendering that hides links from the initial HTML may not show up accurately. Very large sites — tens of thousands of URLs may need a paid crawler with more depth and scheduling options; this tool is built for fast, practical checks, not enterprise-scale continuous crawling. It also reports structure, not intent it won’t tell you which pages should be your priority, only how the current linking reflects what’s already been decided.

Why We Built This

Internal linking is one of the most overlooked levers in technical SEO because nothing about it throws an error — a page can rank poorly for months while every link on the site still resolves fine. Our team runs an internal link audit as a standard part of every site review, because the fix is usually cheap: a handful of contextual links, not a rebuild. We built this tool to make that same check available without a full crawler subscription.

Frequently Asked Questions

Is this internal link checker tool really free?

Yes. There’re no signup and no limit tied to an account for standard scans.

How is this different from a broken link checker?

A broken link checker looks for dead URLs. This tool assumes your links work and instead looks at distribution — which pages get linked to, how often, from where, and with what anchor text.

What counts as an orphan page?

A page with no internal links pointing to it from anywhere else on the site. It might still be indexed via your sitemap, but it’s harder to discover and typically gets less crawl attention.

Can this tool handle large websites?

It works well for most small and mid-sized sites. Very large sites with tens of thousands of pages may need a dedicated crawler with more advanced scheduling and depth controls.
