On a content-rich website, the main menus only show a fraction of the available pages. Entire sections remain accessible only through internal search, contextual links, or intermediary pages that the visitor never encounters if they stick to the navigation bar. Understanding how a site organizes its content, both visible and less visible, changes the way it is explored.
Hidden pages and the actual structure of a website
Most websites distinguish between two layers of content. The first is the visible navigation: the main menu, the footer, the sidebars. The second includes pages that do not appear in any menu. They do exist, indexed by search engines or linked from other internal pages.

This hidden navigation takes several forms. Some pages are only accessible via the site’s internal search or through contextual recommendations displayed at the end of an article. Others are landing pages created for a specific campaign, with no link from the menu. On high-volume sites, these orphan pages can represent a significant portion of the total content.
For a visitor who wants to discover all the sections, relying on the menu is like reading the table of contents of a book where several chapters are missing from the summary. Other tools are needed, and the most direct remains the HTML sitemap, which allows you to explore www.missmarion.fr in detail by listing each section and subsection on a single page.

HTML sitemap and XML sitemap: two distinct navigation tools
The term “sitemap” refers to two very different things depending on the context. An XML sitemap is a technical file intended for search engines, not for visitors. It lists the URLs so that Google or Bing can discover and index them. The user has no reason to consult it.
The HTML sitemap, on the other hand, is a page designed for humans. It presents the complete structure of the site in the form of clickable links, organized by section. It is a fully-fledged navigation tool, often relegated to the footer, but becomes valuable as soon as the site exceeds a few dozen pages.
High-volume content sites are increasingly creating complete HTML sitemaps, distinct from the main menu. These pages list all sections, subsections, and “leaf” pages, including those absent from the traditional navigation. For a methodical visitor, it is the most reliable entry point to map out a site.
Internal search and contextual links: navigating beyond the menu
In recent years, CMSs and large sites have relied on internal search with auto-suggestion and filters as a central means of navigation. Some sites deliberately reduce the depth of their menus and direct visitors to a search bar coupled with thematic “hub” pages.
This approach works when the search is well implemented: real-time suggestions, category filters, relevant results. It fails when the internal engine is approximate or when the visitor does not know what term to search for. In this case, discovery through exploration remains superior to search by query.
Contextual links play a complementary role. An article that links to three other related pages creates a network that the menu cannot reproduce. This network of internal links guides the visitor from one to another, based on thematic affinity rather than hierarchy. It is often the most natural way to discover content that one would not have actively searched for.
When the menu is no longer sufficient
A classic navigation menu works well up to a certain threshold of complexity. Beyond that, architectural compromises force choices: which sections to display, which to hide. The available data does not allow for a universal threshold, but field feedback converges on one point: beyond seven to eight main entries, a menu loses readability.
Dropdown menus attempt to solve this problem by stacking sub-levels, but they create other frictions. On mobile, a menu three levels deep becomes difficult to manipulate. The trend observed on recent sites is towards shorter menus, compensated by effective search and an accessible sitemap.
Concrete method for mapping a complete website
To discover all the sections of a site you are visiting for the first time, a three-step approach yields good results:
- Start with the footer, which often contains a link to the HTML sitemap or sections missing from the main menu (legal notices, archives, secondary categories)
- Use the internal search with generic terms (the name of a supposed section, a broad theme) to bring up pages that the menu does not show
- Consult the HTML sitemap if it exists, looking for a link labeled “sitemap,” “site plan,” or “all sections” in the footer
This method combines structural exploration and active search. It does not guarantee finding every page, especially on sites that maintain content accessible only via direct URL, but it covers the vast majority of published sections.
The limits of manual discovery
On a site with several thousand pages, no manual method allows for exhaustive coverage. Pages protected by authentication, content generated dynamically based on user profile, or parameterized URLs escape any classic exploration. For everyday use (finding a section, understanding a site’s offering, pinpointing specific content), the tools described above are sufficient. For a complete audit, technical crawling tools take over.
The quality of a site’s navigation depends as much on its design as on the visitor’s strategy. A well-thought-out menu facilitates quick access, but complete discovery relies on the sitemap, internal search, and contextual linking between pages. Sites that take care of these three layers offer an experience where every section remains findable, even without being listed in the main menu.
