Internal Link Graph
Discover the hidden architecture of your site's link graph in minutes. Our crawler fetches your homepage + sitemap.xml, then performs a BFS crawl (up to 20 pages) to build a complete internal link graph. Identify pages that are invisible to Google (orphans), your site's authority centers (hubs), and pages that need more internal links to improve crawlability and SEO distribution.

Questions
Everything you need to know about internal link graphs and their impact on SEO.
We fetch your homepage and sitemap.xml, then perform a Breadth-First Search (BFS) crawl to map internal links. We identify orphans (pages with 0 inbound), hubs (pages with many inbound), and underlinked pages (1-2 inbound links). The crawl depth is 1-2 levels to stay within our crawl budget of 20 pages.
Orphan pages have no internal links pointing to them, so Google may never discover them via your site's internal crawl. This means they may not be indexed or ranked, even if the content is valuable. Orphans can be found via external links or sitemaps, but they receive no 'link juice' from your site's internal structure.
Hub pages are the most-linked-to pages in your site—these are your authority centers. Google often ranks hub pages higher because they receive the most internal signals. Orphan pages receive no internal inbound links, making them virtually invisible to your site's internal crawl.
We crawl up to 20 pages per site. We start with your homepage and any pages listed in sitemap.xml, then expand with BFS until we hit the limit or run out of new pages. This balances thorough analysis with being respectful to server resources.
Yes. We crawl your site once per analysis session, store no crawled content, and do not use the data for training. Rate limit is 3 crawls per hour per IP to prevent server strain.
