After publishing many pages
New pages often go live with nothing pointing at them. A crawl lists those pages.
SEO Internal Linking Tool
Internal Linking in SEO
Internal linking in SEO means linking your own pages to each other so visitors and search engines can find them and understand how they relate. Internal Linking Tool at internallinkingtool.com crawls a site from its sitemap and shows which pages nothing links to. It then suggests contextual links with the anchor text and source sentence to use.
What is internal linking and what are internal links
Internal linking is the practice of linking from one page of your site to another, and internal links are those links. They carry visitors from page to page and show search engines how your content fits together.
Internal Linking Tool splits the links on a page into contextual links, the ones inside the article content, and template links, the ones in the nav, header and footer. That split matters, because the two do different jobs.
When to review your internal linking strategy
You should review your internal linking strategy whenever your content grows faster than your links do.
Before a content refresh
The link suggestions show which older pages could point at the page you just updated.
During an SEO audit
Both orphan lists and the silo matrix give you a clear view of how links sit between sections.
After a site migration
The re-crawl diff on paid plans shows new orphans, fixed orphans, pages added and pages removed.
How to run an internal linking audit
To run an internal linking audit with Internal Linking Tool, you verify your site, crawl it and work through the report.

- 03
Choose Sign up when you want a whole-site crawl.
- 04
Verify the site with a meta tag in the page head, a small text file at a known path, or a DNS TXT record.

- 07

Internal link checker limits and what it reads
The internal link checker reads static HTML, and the free plan has the limits listed below.
The crawl reads the HTML the server sends, the same HTML a search engine reads on a normal visit. If your site builds its links in the browser with JavaScript, those links are not seen.
Pages behind a login, a cookie wall or bot protection are counted as failed pages and named in the report. This tool does not insert links into your site, so every link you add is added by you.

Orphan pages and the two orphan lists
Orphan pages are pages in your sitemap that no other page on the site links to. Internal Linking Tool also reports contextual orphans, which are pages linked only from the template, such as the navigation, header and footer.
Every crawl reports both lists, because one is a page nobody can find and the other is a page that no other page vouches for.
Internal linking structure and the silo matrix
Internal linking structure is the pattern of links between your pages and sections. The silo matrix in every plan shows link counts between the top-level sections of your site.
Use it to spot sections that barely link to each other.
Internal linking best practices from the suggestions
Internal linking best practices start with natural anchor text in a sentence that is really about the target page. Each suggestion gives the source page, the target page, the anchor, the sentence, a similarity score and the matched terms.
Anchors are never invented, since each one is a phrase already on the source page. A score is a number, not a verdict, so you decide whether the sentence fits.
