An HTML sitemap is a page that lists all the links of a website in a tree structure readable by a human visitor. It differs from the XML sitemap, a technical file intended for search engines for indexing. Both serve complementary functions, but it is the HTML sitemap that concretely transforms the navigation of a lost user into a smooth journey.
HTML Sitemap and XML Sitemap: Two Files, Two Audiences
The confusion between these two formats remains common. The XML sitemap is a structured file that crawlers (Googlebot, Bingbot) read to discover and index pages. It contains neither formatting nor visual hierarchy: it is a raw list of URLs accompanied by metadata (last modified date, priority).

The HTML sitemap, on the other hand, is aimed at visitors. It displays the complete tree structure of the site with clear headings, organized by sections and subsections. A user who cannot find what they are looking for via the main menu can go there to pinpoint the exact page they need.
Extensions like SEOPress now offer to generate both formats from a single interface, with a HTML sitemap that can be activated with one click and including images to enhance content exploration. This dual coverage (for humans and bots) strengthens both user experience and SEO. On the Kabanes sitemap, this logic is applied with a clear visual structure that groups each category of content.

Site Map Structure: Organize Before Publishing
Publishing a sitemap without validating its structure is akin to distributing a rough draft. The structure should reflect the mental logic of visitors, not the internal organization chart of the company.
Card Sorting and Tree Testing to Validate Architecture
Two UX methods allow for checking that a structure meets the real expectations of users. Card sorting involves asking a panel to sort page titles into categories that seem logical to them. The result often reveals groupings that the project team had not considered.
Tree testing then comes into play: the candidate structure is presented to testers, and they are asked to find specific information. The success rate and the number of clicks required indicate whether the structure works or if certain branches need to be reorganized.
These empirical tests, which can be conducted with accessible online tools, prevent locking a sitemap into internal assumptions that have never been tested in the field.
Pages to Include and Pages to Exclude
A sitemap is not a duplicate of the navigation menu. It should provide a comprehensive yet readable view:
- Structural pages (home, main sections, stable sub-sections) make up the skeleton of the sitemap and guide the reading
- Legal pages (legal notices, privacy policy) deserve to be included for reasons of transparency and compliance
- Duplicated pages, internal search result pages, and filter or pagination pages have no place: they clutter the sitemap without adding navigational value
For dynamic sections like a blog or news section, listing only the main categories is sufficient. Including each individual article would render the sitemap unreadable in a few months.
Accessibility of the Sitemap: WCAG Compliance and Keyboard Navigation
A complete sitemap loses all its usefulness if it is not accessible to people with disabilities. The WCAG 2.1 and 2.2 guidelines impose concrete requirements that go beyond general web design best practices.
Screen reader users benefit directly from a well-constructed sitemap. Navigating a site page by page to understand its architecture requires considerable cognitive effort. The sitemap provides a global view of the structure in one place, without exploratory navigation.
WCAG criteria require a minimum contrast ratio of 4.5:1 for navigation elements. Keyboard focus must be managed correctly in dropdown menus and navigation drawers. A sitemap link that does not receive keyboard focus is invisible to anyone who cannot use a mouse.
The standard also requires that each means of navigation be complemented by at least one other. Offering a main menu, a sitemap, and a search engine meets this requirement and provides three distinct paths to the same content.
Responsive Design of the Sitemap on Mobile
On a desktop screen, a multi-column sitemap remains readable. On mobile, this same layout becomes a nightmare of horizontal scrolling. The responsive design of the sitemap imposes specific choices.
The structure should fold in an accordion style or in expandable levels. The user clicks on a main section to reveal its sub-pages without loading a new page. This mechanism reduces the apparent length of the sitemap while maintaining comprehensiveness.
- The touch areas of each link must be wide enough to avoid accidental clicks, in accordance with mobile accessibility recommendations
- The text of the headings must remain readable without zooming, which requires an appropriate font size and generous vertical spacing between lines
- Levels of nesting beyond three depths become difficult to represent on a small screen: it is better to simplify the structure than to force an unreadable indentation
A sitemap that works on mobile is not a reduced version of the desktop sitemap. It is an interface designed from the start for touch, with interactions suited for the thumb.
The maintenance of the sitemap remains the weak point of most sites. A sitemap generated automatically via a CMS or a dedicated extension updates with each page publication. A manually constructed sitemap requires regular checking, lest it offer broken links that degrade visitor trust.
The choice between these two approaches depends on the volume of content and the frequency of publication. In either case, an outdated sitemap does more harm than good.
