Why internal linking is a ranking lever most sites underuse
Internal links are how PageRank flows through your site. When Page A links to Page B, a portion of A's authority passes to B. Sites with well-structured internal linking have their most important pages accumulating the most authority — while orphaned pages receive nothing, regardless of how good the content is.
The problem is that internal link structure is almost always accidental. Content teams add links to whatever feels relevant at time of writing. The result after 100+ articles is a chaotic graph where your best content is buried and your weakest pages are the most-linked by pure accident (think: the blog index page getting linked from every header).
This tool makes the invisible visible. The force graph immediately shows you which pages are pulling all the authority (hubs), which are completely isolated (orphans), and which related pages should be linking to each other but aren't. Internal link audits that used to require Screaming Frog or a paid crawl tool can be done here in under a minute with no download or account.
How link equity flows (simplified)
Homepage → Category pages
Homepage distributes authority to all category pages it links to. Most important flow.
Category → Pillar articles
Category pages pass authority down to pillar content. Determines which articles rank.
Pillar → Supporting articles
Pillar content shares authority with related subtopic articles. Builds cluster depth.
Supporting → Orphan pages
Orphan pages receive zero. No links in = no equity = no ranking signal.
Reading your internal link map: what to fix first
When you get your results, focus in this order:
Orphans with high outbound links
These pages link to others but receive nothing back. They have content worth promoting — just no one is pointing to them. Add links from topically related hubs.
Hubs pointing to unrelated content
If your highest-linked pages are not your most important content (e.g., the contact page or tag pages), audit those pages and redirect link equity toward pillar content.
Pages with inDegree = 1
Single-link pages are fragile. If that one source page gets restructured or deleted, the target loses all internal authority. Build redundancy by adding 2-3 sources.
The Fix tab opportunities
The tool surfaces related pages that don't link to each other. These are your easiest wins — add a contextual anchor in existing content rather than writing new pages.

FAQ
What is an internal link map?
An internal link map is a visual representation of how pages on your website connect to each other through internal links. It shows which pages are "hubs" (receiving many links from other pages) and which are "orphans" (receiving no links at all). Search engines use internal link structure to discover and prioritize pages — a page that receives no internal links is effectively invisible to crawlers beyond the sitemap itself.
What is an orphaned page and why does it matter?
An orphaned page is a page that exists in your sitemap but has no other pages on your site linking to it. Because PageRank flows through internal links, orphaned pages receive zero link equity from the rest of your site — they rank only on their own thin authority. Fixing orphaned pages is often the fastest internal linking improvement you can make: find the most closely related content and add a contextual link.
How do I find orphan pages without Screaming Frog?
Screaming Frog is the most-cited tool for orphan page detection, but it requires a desktop download and the free version caps at 500 URLs with no visualization. This tool finds orphan pages directly in your browser — paste your domain URL and we auto-discover your sitemap, crawl each page, and flag every URL that has zero inbound internal links. No download, no account, no 500-URL cap for the crawl itself. The Fix tab also surfaces which existing pages should link to each orphan based on topic overlap.
Is internal linking important for SEO?
Yes — internal linking is one of the most controllable ranking levers you have. Every internal link passes a fraction of the linking page's authority to the target page. Sites with well-structured internal linking have their most important pages accumulating the most PageRank, while orphaned pages receive nothing regardless of content quality. Internal linking also determines which pages Google's crawler discovers and how frequently it revisits them. A thorough internal link audit often yields ranking improvements without writing a single new page.
What is a hub page?
A hub page is a page that receives a disproportionately high number of internal links relative to the site average. Hub pages accumulate the most PageRank and are typically your most important pages for ranking — homepage, main category pages, key pillar content. If your hub pages are the wrong ones (e.g., your privacy policy is the most-linked page), that's a structural problem worth fixing.
How is PageRank calculated in this tool?
This tool uses a simplified PageRank algorithm (power iteration, 25 steps, damping factor 0.85) applied to the internal link graph. It is not Google's actual PageRank score — Google's is proprietary and factors in many additional signals. The score here is a relative measure: pages with higher scores receive more link equity from the rest of your site. Use it to compare pages within the same site, not across different sites.
How does the tool find links?
The tool fetches your sitemap to discover up to 100 pages, then crawls each page in parallel and extracts all links that point to other pages on the same domain. External links (to other domains), fragment links (same-page anchors), and links with query parameters are filtered out. The result is a clean graph of same-domain, page-to-page connections.
What does the "Fix" tab show?
The Fix tab lists link opportunities: pairs of pages that cover related topics (based on URL slug similarity) but don't currently link to each other, where the target page has zero inbound links. These are your highest-priority internal linking tasks — adding these links directly lifts your orphaned pages' authority and improves topical depth signals for related content clusters.
Do I need to sign up?
No. The full analysis — force graph, hub list, orphan list, and link opportunities — is completely free with no account required. There is a limit of 3 analyses per day per IP address.
