You are looking for specific information on a website, but the main menu leads you nowhere. You try the search bar, but the results are vague. There is a shortcut often overlooked: the sitemap page. This site map, accessible with one click, lists all available pages and directs you straight to the desired content. However, you need to understand how it works and what distinguishes a useful sitemap from a useless file.
HTML Sitemap and XML Sitemap: Two Files, Two Audiences
The term “sitemap” encompasses two different realities. Confusing them means missing out on their respective functions.
The HTML sitemap is intended for human visitors. It appears as a standard web page, with clickable links organized by categories. You can access it from the footer of the site, sometimes from the menu. Its role is to allow you to visualize the site’s structure and reach any section without navigating through multiple levels of menus.
The XML sitemap, on the other hand, is aimed at search engines. It is a technical file, readable by Google or Bing, that lists the site’s URLs along with metadata (last modified date, relative priority). A user who opens a sitemap.xml file encounters raw code, not a readable page.
When we talk about “navigating easily thanks to a sitemap page,” it is indeed the HTML sitemap that matters. To illustrate this principle, the sitemap page of Lozzoo organizes its content into clear categories, making it possible to find a section without going through the search bar.
What Makes a Sitemap Page Truly Navigable
Not all HTML sitemaps are created equal. Some sites display a raw list of several hundred links, without hierarchy or grouping. The result is worse than the initial problem: instead of simplifying navigation, the page becomes a wall of incomprehensible text.
A Readable Hierarchical Structure
An effective sitemap reproduces the logic of the site. Major sections appear first, followed by subcategories, and then individual pages. Three levels of depth are sufficient in most cases. Beyond that, the reader gets as lost as in the main menu.
Explicit Link Titles
Each link should have text that describes the destination page. “Article 247” or “Product Page” does not inform anyone. A good title contains the subject of the page in a few words.
The concrete criteria for a useful HTML sitemap include:
- Sections are grouped by theme, not listed in chronological order of page creation
- Obsolete pages, redirects, and duplicate content are not included
- The sitemap is accessible from the site’s footer, with one click from any page
- The page loads quickly, even if the site contains several hundred URLs
XML Sitemap and SEO: Errors That Harm Indexing
On the technical side, the XML sitemap also deserves attention. A poorly configured file sends contradictory signals to search engines.
The sitemap should only contain pages eligible for indexing. URLs with noindex, 301 redirects, 404 error pages, and non-canonical variants must be excluded. Including these addresses is like asking Google to explore dead ends, which dilutes its focus on your useful pages.
The Last Modified Date: A Freshness Signal, Not a Gadget
The lastmod tag must reflect a real change in content. Updating this date without changing the page text does not fool search engines. Google values a reliable lastmod more than repeated submissions of the file.
Another point to know: the “ping” method to notify Google of a sitemap update is no longer valid. Google has officially deprecated this function. The only two recognized methods are declaring the sitemap in the robots.txt file and submitting it via Google Search Console.
Specialized Sitemaps: Images, Videos, and JavaScript Content
A classic XML sitemap lists web pages. However, some content escapes standard search engine crawling.
Images loaded via JavaScript, for example, are not always detected by indexing bots. An image sitemap allows you to explicitly signal these visuals and improve their visibility in Google Images.
The same principle applies to videos. A video sitemap transmits metadata that the engine cannot extract on its own: title, thumbnail, duration, description. For a site that regularly publishes video content, this supplementary file represents a concrete visibility lever.
- Image sitemap: useful when visuals are dynamically injected or poorly linked in the HTML
- Video sitemap: relevant for transmitting metadata (title, duration, thumbnail) to engines
- News sitemap: reserved for sites registered in Google News, to speed up the indexing of recent articles
Checking and Maintaining Your Sitemap Over Time
A sitemap created once and then forgotten gradually loses its value. Pages evolve, some disappear, and others are created.
Maintaining the sitemap is part of the site’s ongoing management. With each page deletion, ensure it no longer appears in the XML file or the HTML page. With each addition of a section, integrate it into the HTML sitemap so that visitors can find it.
For the XML sitemap, most CMS (WordPress, Shopify, Webflow) automatically generate the file. Still, check that excluded URLs (noindex, redirects) do not sneak in by default. A quick audit via Google Search Console can help identify coverage errors related to the sitemap.
The sitemap, whether HTML or XML, remains a simple tool that serves a specific function: to make visible what exists. From the visitor’s perspective, it shortens the path to information. From the search engine’s perspective, it clarifies the site’s structure and guides exploration. The only condition: only list what deserves to be found.
