What does this tool check?
What problems does this find?
The issues this check most often surfaces on real sites:
- Related pages that never link to each other
- Strong pages hoarding authority instead of passing it down
- Important pages with too few inbound internal links
What do I do after the check is complete?
Linking related pages to each other helps them rank. We found the most valuable links your site is missing — a free account shows you the exact words to use and where to put them.
- 1
Start with the pages that matter commercially
Work down the list in order of how much you care about the page, not how bad the number looks. A flagged page nobody needs to find is not worth an hour of your time.
- 2
Fix the cause, not the symptom
Most findings here are structural: a page is unreachable, under-linked, or competing with another page. Adding one contextual link from a strong, relevant page usually fixes more than editing the page itself.

Re-run this check to confirm the fix landed
The check is free and takes a couple of minutes. Re-crawling after a change is the only way to know it worked — and the full audit tracks the difference between crawls for you.
Why internal link checker matters for SEO
Internal links pass authority between your pages and tell search engines how they relate to each other. Most sites leave easy rankings on the table simply because related pages never link together, so authority pools on a few URLs while the rest go without. Unlike backlinks, internal links cost nothing and need no outreach — adding the right ones is one of the few ranking levers you fully control and can act on today. The hard part isn't knowing internal links matter; it's knowing exactly which link to add and where, which is what this analysis is built to answer.

Internal Link Checker: frequently asked questions
What does an internal link checker do?
It analyses how the pages on your site link to each other, then finds pages that should be linked but aren't. RankForge goes further than a broken-link scan: it models authority flow and topical relevance to recommend the specific links most likely to improve rankings.
Why are internal links important for SEO?
Internal links distribute authority (PageRank) through your site and tell search engines how pages relate. Strategic internal linking is one of the few SEO levers you fully control — no outreach, no waiting on third parties.
What do I get for free vs. with an account?
The free checker shows you which source and target pages to connect. A free account unlocks the exact anchor text to use, the precise paragraph to place each link in, the full ranked list, a client-ready PDF, and weekly re-crawls.
