Site Structure
The Site Structure analysis tab shows how pages are organised across your site — how deep they sit from the homepage and how the URL hierarchy groups them. It surfaces orphaned and unreachable pages that search engines are unlikely to find, and flags pages buried too many clicks from the homepage.
Depth distribution
The depth distribution view opens with four metric tiles summarising the crawl:
Below the tiles, a histogram shows how many pages sit at each click depth from the homepage. Depth 0 is the homepage itself, depth 1 is every page the homepage links to directly, depth 2 is every page reachable in two clicks, and so on. A healthy site concentrates most of its pages within three clicks of the homepage. Pages at depth 4 or beyond are harder for visitors and search engines to reach, and each additional click reduces the likelihood that the page will be crawled and indexed.
One issue rule is tied to click depth:
The rule fires at notice severity rather than warning or critical because depth alone does not make a page inaccessible — it makes it less convenient. A page at depth 5 with strong internal links pointing to it is in better shape than a page at depth 2 with none. Depth is a signal worth reviewing, not an error to fix mechanically.
URL tree
The URL tree view organises every crawled page into an expandable tree based
on URL path segments. A site whose pages live at
/blog/2024/post-title and
/blog/2024/another-post shows a
/blog node containing a
/2024 node containing both posts.
Each node in the tree displays three badges:
Expanding a node reveals its children — either deeper path segments or individual page URLs. The tree makes it straightforward to spot entire sections of a site that are poorly linked: a branch with a high page count and a high orphan count is a section that exists in the URL hierarchy but is not woven into the site's navigation.
Orphans and unreachable pages
Both metrics appear in the depth distribution tiles, but they describe different problems and call for different responses.
Orphan pages
An orphan page has zero inbound internal links. No other page on the site links to it. It may still be reachable if it appears in an XML sitemap or if external sites link to it, but from the perspective of a visitor browsing the site — or a search engine following links — it does not exist. Orphans typically appear when a page is created but never added to navigation, or when every page that once linked to it is removed or updated.
Unreachable pages
An unreachable page does have inbound internal links, but none of those linking pages are themselves reachable from the homepage. The page sits in a disconnected cluster — a group of pages that link to each other but have no path back to the main site. This happens when an entire section is removed from the navigation without removing its internal cross-links: the pages still reference each other, so none of them are orphans by the strict definition, but a visitor starting at the homepage cannot reach any of them.
The distinction matters for prioritisation. Orphans are simpler to fix — add a link from an appropriate page. Unreachable pages may need a broader structural change, because the problem is not a single missing link but a missing connection between two clusters of pages.
