Why do internal links matter for SEO?

Internal links help search engines discover pages, understand topical relationships, and distribute authority across the site. They also help users move deeper into the content and find relevant next steps.

What counts as a weak internal link?

Weak patterns include empty anchor text, repetitive generic anchors like "click here", too many links pointing to the same destination, or important pages receiving little or no contextual linking from related content.

Does this tool crawl the whole site?

It runs a small same-domain crawl sample, not a full enterprise crawl. That keeps the audit fast while still surfacing link-pattern problems, weak pages, and obvious opportunities.

Can I use this after publishing a new article?

Yes. It is useful after publishing or refreshing content because it shows whether the new page gets enough internal support, whether it cites outside sources appropriately, and which pages should link to it next.
