A visitor who cannot find what they are looking for within a few seconds leaves the site. The organization of a website’s layout directly affects the time spent on each page, the bounce rate, and the ability of search engines to properly index the content. Structuring pages according to a clear logic for the user, and not just for SEO, remains the most underestimated lever when creating or redesigning a website.
Navigation and assistive technologies: the test that most sites ignore
Before discussing the hierarchy or menu, a recent constraint changes the game. Since June 28, 2025, the European Accessibility Act requires certain private websites (e-commerce, banking services, passenger transport, telecommunications) to offer navigation that can be used with assistive technologies. In France, micro-enterprises in services may benefit from an exemption under certain conditions, but other affected structures must adapt their interface.
In practical terms, this means that the organization of the site must be tested with a screen reader, not just with valid users. A dropdown menu that is perfectly readable on the screen can become a trap if the links are not accessible via keyboard or if the hierarchy of headings is inconsistent.
Have you ever noticed that a well-designed site can still be difficult to use? This discrepancy often arises because the hierarchy has been thought out visually, without checking the underlying HTML structure. A good site map serves both indexing bots and people who navigate without a mouse.
A concrete example of this logic applied: the site map mrseb.fr presents its pages in a readable hierarchy that facilitates exploration, whether using a standard browser or an assistive tool.
Website hierarchy: three levels maximum to keep the visitor
The click depth is the most concrete criterion for judging the quality of a site map. Every useful page must be accessible within three clicks from the homepage. Beyond that, the abandonment rate rises, and search engines give less weight to buried pages.
Structuring pages by search intent
Grouping pages by theme is not enough. The question to ask for each section is: what information is the visitor looking for when they arrive here? A catch-all “services” page forces the user to sort through it themselves. It is better to create a page for each commercial offer, with a title that matches what customers actually type into Google.
Take a restaurant website. Rather than a single “Our Menu” page, separating “Lunch Menu,” “Dinner Menu,” and “Wine List” allows each page to respond to a specific query and rank for a distinct keyword.
Content hierarchy and internal linking
Once the pages are created, their organization in the main menu and the internal links between them determine the visitor’s flow. Here are the elements to check:
- The main menu does not exceed seven entries. Beyond that, the user hesitates, and the decision time increases, which penalizes the experience on mobile.
- Each deep page receives at least one link from a higher-level page. An orphan page (without incoming links) is invisible to search engines.
- Internal links use descriptive anchors, not “click here.” “See our wine list” informs both the reader and the indexing bot.
Bread crumbs and HTML site map: two markers still underutilized
The breadcrumb displays the path taken by the visitor from the homepage. According to the Baymard Institute, this element remains insufficiently exploited on e-commerce sites, even though it reduces disorientation, especially on mobile.
A well-implemented breadcrumb decreases reliance on the back button and helps Google understand the hierarchy between pages. For it to work, the site’s structure must be strictly pyramidal: each page has only one logical parent.
The HTML site map (the page that lists all the URLs) serves a complementary role. It offers an overview to lost visitors and indexing bots. Unlike the XML sitemap (a technical file intended for search engines), the HTML site map is primarily aimed at humans. It should therefore be organized by readable categories, not in raw alphabetical order.
Common mistakes in website organization
Some mistakes recur on the majority of sites, including those of large platforms. A documented hierarchy does not guarantee smooth navigation if the implementation diverges from the initial plan.
- Multiplying sub-menus beyond two levels creates a labyrinthine navigation. On mobile, nested menus become nearly unusable.
- Duplicating the same page in multiple sections of the menu confuses the structure in the eyes of Google and dilutes SEO.
- Neglecting consistency between the menu, breadcrumb, and internal linking produces contradictory signals for search engines.
- Forgetting to test keyboard navigation excludes part of the users and exposes to non-compliance since the implementation of the European Accessibility Act.
Every structural change deserves a real test: ask someone who does not know the site to find specific information in less than three clicks. If the person hesitates, the structure needs to be simplified.
An effective website map is not judged by its complexity or the number of pages it contains. It is judged by the time it takes a visitor, regardless of their mode of navigation, to find exactly what they were looking for.
