A visitor arrives on your site, searches for specific information, and leaves after a few seconds without finding it. The problem rarely lies with the content itself. It stems from the way the pages are organized among themselves. Optimizing a site’s structure for effective navigation is primarily about reducing the number of clicks between the homepage and the useful information, while making each path predictable.
Click Depth and Page Hierarchy: What Google Reads First
Before thinking about the menu design or the color of buttons, look at how many clicks separate your homepage from your most sought-after content. This number is called click depth. Every useful page should be accessible within three clicks maximum.
Why three? Because each additional click increases the likelihood that the visitor will abandon their search. And because Google’s indexing bots crawl a site by following internal links: the deeper a page is, the less “SEO weight” it receives.
In practical terms, this means that your site’s hierarchy should resemble a wide and shallow tree. The homepage links to main categories (five to seven are sufficient), and each category leads to sub-pages. When observing the structure of the Jean-Louis Garret site, you can see how a sitemap makes this hierarchy visible: each branch is identifiable, and each page has its place in a coherent whole.
If an orphan page exists somewhere on your site without any internal links leading to it, Google will likely not find it, and neither will your visitors.
Website Hierarchy: Building Categories that Reflect User Search
You may have noticed that some sites display menus with a dozen sections, half of which do not correspond to anything you would search for? This mismatch often arises from a hierarchy thought out from the internal perspective of the company, not from the visitor’s.
The categories in your menu should match the words your users type into Google. For example, if you sell furniture, your visitors are searching for “convertible sofa” or “extendable table,” not “comfort range” or “prestige collection.”
Testing Categories with Card Sorting
Card sorting is a simple exercise. You list all the pages of your site on cards. You ask five or six outsiders to group them by theme and name each group. The titles they spontaneously choose are almost always clearer than those you had planned.
This method avoids a common pitfall: creating overlapping categories. When a visitor hesitates between two sections to find the same information, navigation is already broken.
Internal Linking and Contextual Navigation: Guiding Without Overloading
The main menu is just one of the navigation tools. Internal linking, meaning the links placed within the content of your pages, plays a crucial role for both SEO and user experience.
A good internal link meets three criteria:
- Its anchor (the clickable text) precisely describes the destination page, not a vague “click here” or “learn more”
- It connects two thematically related contents, which helps Google understand the relationships between your pages
- It is placed within the body of the text, where the visitor is already reading, not relegated to the bottom of the page where no one scrolls
Every important page on your site should receive at least two or three internal links from other pages. If a page is only linked from the menu, it remains fragile in your structure.
The Breadcrumb Trail, an Underestimated Guide
The breadcrumb trail displays the path taken: Home > Category > Sub-category > Current Page. This small navigation element helps the visitor locate themselves, go up a level without using the back button, and provides Google with clear information about the hierarchy of your pages.
On mobile, the breadcrumb trail compensates for the absence of a permanently visible menu. It becomes the only positional reference within the site.
Navigation Accessibility: A Legal Requirement Since June 2025
Since June 28, 2025, the European Accessibility Act imposes digital accessibility rules on several private sectors in Europe, including e-commerce, banking services, and transportation. Keyboard navigation, the semantic structure of HTML, and compatibility with assistive technologies (screen readers, for example) are part of the obligations.
On the technical side, the European reference is evolving towards WCAG 2.2 with the publication of the EN 301 549 v4.1.1 standard in September 2026. Until this version is cited in the Official Journal of the European Union, the formal reference remains based on WCAG 2.1 level AA.
What this changes for your site’s structure:
- Clickable targets (buttons, menu links) must be large enough to be usable by finger or with an assistive device
- The keyboard focus must never be hidden by an overlapping visual element (a cookie banner, for example, that would hide the menu)
- Drag-and-drop interactions must offer an accessible alternative
Designing accessible navigation also improves the experience for all visitors, not just for people with disabilities. Larger buttons, visible focus, and clean HTML structure benefit every user, on every device.
Most mobile e-commerce sites remain particularly weak on category navigation, according to research from the Baymard Institute. This gap between general recommendations and the actual observed experience shows that structural work is not limited to desktop: it must be tested and corrected screen by screen.
A site whose structure reflects the search logic of visitors, whose internal linking distributes SEO weight coherently, and whose navigation complies with current accessibility standards covers the three pillars of a solid web architecture. The rest, such as menu colors or transition animations, is merely decoration. The structure, however, determines whether your pages will be found, read, and understood.
