A sitemap lists all the accessible URLs of a domain in a format readable by both humans and search engines. On a professional site like Igor Web, this page serves a dual purpose: helping visitors quickly find specific content and signaling to indexing bots the complete structure of the site.
HTML Sitemap and XML Sitemap: Two Formats, Two Distinct Functions
The term “sitemap” encompasses two technical realities that must be distinguished before going further. The XML sitemap is a file intended for search engines. It contains the raw list of URLs, their last modification date, and a priority indication. Internet users never consult it directly.
The HTML sitemap, on the other hand, takes the form of a standard web page. It displays the site’s links in a hierarchical list format, with readable titles. This is the version found when consulting the page selection on Igor Web, which presents the site’s structure as clickable links organized by category.
In practice, a well-structured site publishes both. The XML file feeds Google, Bing, and other indexers. The HTML page serves as a safety net for lost visitors or for those who prefer to browse a summary rather than navigate menu by menu.
Navigation via Sitemap: When the Main Menu is Not Enough
A navigation menu rarely displays more than two levels of depth. Beyond that, usability deteriorates: nested submenus become difficult to manipulate on mobile, and some secondary pages simply disappear from view.
The sitemap addresses this limitation. It provides access to deep pages (legal notices, general conditions, specific service pages) without forcing the visitor to guess the path. For an IT services site offering both troubleshooting, training, and web development, the depth of the structure increases quickly.
Three Cases Where the Sitemap Accelerates Search
- A prospect is looking for a specific service (Google Workspace training, remote access solution) and cannot find it in the main menu within two clicks.
- A user returns to the site after several weeks and no longer remembers the location of a page they had consulted.
- An internal audit checks that all published pages are accessible and correctly linked to each other, without broken links or orphan pages.
Digital Accessibility and Site Structure: A Direct Link
Since June 28, 2025, the European Accessibility Act applies to digital services for consumers: online commerce, banking services, transportation, telecommunications. Micro-enterprises with fewer than ten employees and a turnover or balance sheet of less than two million euros benefit from an exemption.
A purely informational site without transactions or reservations does not fall directly within the scope of this regulation. Accessibility remains, however, a criterion of technical quality, and the structure of the pages directly influences assisted navigation.
Screen readers, used by visually impaired individuals, rely on the hierarchy of headings (H1, H2, H3) and internal links to navigate a site. A well-constructed HTML sitemap provides an alternative entry point that can be utilized by these tools. Automated tests only detect part of the accessibility issues: checking keyboard navigation, forms, and navigation with a screen reader requires additional manual checks.
Optimizing an HTML Sitemap: Technical Criteria to Follow
Publishing a page listing all URLs is not enough. A useful sitemap adheres to several construction principles.
- Group links by logical category (services, resources, legal information) rather than in alphabetical or chronological order.
- Use explicit link titles: “Dell Expert Solutions” is more useful than “Page 12” or “Click here”.
- Keep the page updated: every URL removed or modified on the site must be reflected in the sitemap to avoid 404 errors.
- Limit the depth to a maximum of three levels in the list to keep the page scannable in a few seconds.
An outdated or poorly organized sitemap produces the opposite effect of what is intended. A visitor who encounters broken links loses trust in the reliability of the site.
Update Frequency
On a site with little content evolution (showcase site, portfolio), a quarterly check is sufficient. For a site with an active blog or regularly modified service pages, a monthly update of the HTML sitemap prevents the accumulation of dead links.
The XML file, on the other hand, can be automatically regenerated by most CMS (WordPress, Joomla). The HTML page requires manual intervention or a dedicated module, which explains why it is often neglected.
The sitemap remains an underestimated navigation tool. On a professional site covering multiple areas of activity, it is the most direct means to verify that each published page is accessible, correctly named, and linked to the rest of the structure.
