A sitemap structures all the pages of a domain in a readable tree format. The question arises: what elements distinguish a truly useful sitemap from a simple list of links that no one consults? The differences between a well-designed sitemap and a neglected one can be measured on three axes: accessibility, SEO, and visitor behavior.
HTML Sitemap or XML Sitemap: What Each Format Brings to Navigation
Two formats coexist, and their functions do not overlap. The XML sitemap is aimed at search engine indexing bots. The HTML sitemap, on the other hand, is intended for human visitors. Confusing the two means ignoring half of the problem.
| Criterion | HTML Sitemap | XML Sitemap |
|---|---|---|
| Main Recipient | Visitors, screen readers | Googlebot, Bingbot |
| Location | Page accessible from the footer | File at the root of the server |
| Content | Readable tree structure with clickable links | List of URLs with metadata (date, priority) |
| Direct SEO Impact | Internal linking, PageRank distribution | Discovery and crawling of deep pages |
| Accessibility Impact | Alternative navigation for keyboard and screen readers | None for the end user |
A site that only offers an XML sitemap deprives its visitors of a global navigation tool. Conversely, an HTML sitemap without an XML sitemap slows down the indexing of recent or deep pages. The two formats work in complement, not in replacement.
To observe a concrete example of a well-organized HTML sitemap, the sitemap of make-world.org illustrates a category tree with a clear hierarchy between main sections and subpages.
Legal Accessibility Requirements and Sitemap: What the European Accessibility Act Changes
Since June 28, 2025, the European Accessibility Act (EAA) imposes digital accessibility obligations on most B2C online services in the European Union. This includes e-commerce, banking services, passenger transport, ticketing, and electronic communications.
In France, RGAA 4.1.2 serves as the compliance reference with 106 criteria. Among the required documents are: an accessibility declaration, a multi-year plan, and an annual action plan.
The link to the sitemap is direct. Screen reader users cannot always navigate a complex dropdown menu. An HTML sitemap provides them with an overview of the structure without having to tab through every interactive element on the page.
RGAA Criteria Related to Alternative Navigation
The RGAA requires that each page be reachable by at least two distinct navigation methods among the main menu, the sitemap, and the internal search engine. A site without an HTML sitemap that also lacks an internal search engine is non-compliant on this criterion.
- The sitemap must reflect the actual structure, not a simplified or outdated version that omits entire sections.
- The links in the sitemap must be descriptive: “Our project management training” rather than “Page 12” or “Click here.”
- The sitemap page itself must respect the hierarchy of headings (H1, H2, H3) so that screen readers can navigate by levels.
An outdated sitemap constitutes an accessibility barrier, not an aid. Broken links to deleted pages generate 404 errors that block assisted navigation.
Internal Linking and SEO: How the Sitemap Redistributes Authority Among Pages
Search engines follow internal links to understand a site’s hierarchy. A page linked from the sitemap benefits from an additional link from a page that is itself accessible from all others (via the footer, typically).
This mechanism particularly benefits deep pages. A blog post published two years ago and absent from the main menu may lose visibility if no internal link points to it. The HTML sitemap acts as a safety net for internal linking by ensuring that no indexable page remains orphaned.
Pages to Include and Pages to Exclude
Not all pages belong in a sitemap intended for visitors. Legal notice pages, privacy policy pages, or internal search result pages do not contribute to navigation.
- Include: category pages, product or service sheets, blog articles, contact pages, and main forms.
- Exclude: thank-you pages after forms, login pages, pages duplicated by filters or URL parameters.
- Special case: paginated pages (page 2, page 3 of a blog) do not appear in the sitemap. Only the first page of each category is included.
A sitemap that lists hundreds of pages without logical grouping loses its navigational function. Grouping links by categories with subtitles allows visitors to scan the page in seconds.
Frequency of Sitemap Updates and Signals Sent to Search Engines
A static sitemap, created once and never revised, eventually diverges from the actual structure of the site. The consequences are twofold: on the visitor side, dead links erode trust; on the SEO side, contradictory signals are sent to indexing bots.
For sites that regularly publish content (blog, product catalog), the sitemap update must follow the publication pace. Some CMS like WordPress automatically generate the XML sitemap but not the HTML sitemap, which often remains a manual page.
Automatic generation solutions exist via dedicated plugins. They crawl the site’s structure and rebuild the sitemap with each new publication. However, they do not always filter out unnecessary pages, requiring periodic checks.
The sitemap remains one of the few elements of a website that serves three audiences simultaneously: hurried visitors, users with disabilities, and indexing bots. Sites that treat it as a technical formality miss out on a navigation and SEO lever whose maintenance cost is relatively low.
