A blog that publishes regularly will eventually accumulate dozens, sometimes hundreds, of articles. Without a dedicated solution, some of this content becomes difficult to find for readers who don’t know the exact URL. An HTML sitemap solves this problem by bringing together links to every blog post on a single page, organized by category or date.
Orphan pages on a blog: the problem an HTML sitemap solves
Competitors tend to focus on XML sitemaps and the overall structure of a business website. Blogs deserve a different perspective because their publishing dynamics create a recurring pitfall: orphan pages.
An orphan page is an article that isn’t linked to from any other page on the blog. An XML sitemap can alert search engine crawlers to its existence, but human readers have no way to reach it through the site’s usual navigation. The article exists, Google may know about it, but visitors can’t find it.
On an active blog, this problem grows over time. Early posts sink deeper into the pagination, disappear from “recent articles” widgets, and gradually lose visibility. An HTML sitemap acts as a safety net: by listing every published URL, it ensures that no content is completely isolated from the site’s navigation.
A practical example of this approach can be found on the Les Carnets du Web sitemap, where every article remains accessible from a single page, regardless of how old it is.
HTML sitemap and XML sitemap: distinct roles in blog navigation
They share the same name, but serve different audiences. An HTML sitemap is a standard web page that human visitors can read. An XML sitemap is a technical file read by the crawlers used by Google, Bing, and other search engines.
For a blog, this distinction has a direct impact on navigation. An XML sitemap helps search engines discover new posts faster, but it doesn’t create a path for readers. An article indexed thanks to an XML sitemap can still be impossible to find in the blog’s menus, categories, and internal links.
An HTML sitemap addresses this imbalance. It provides an overview that neither the main menu nor the sidebar can offer, since both have a limited number of links they can display. A menu simply can’t include everything on a blog with hundreds of articles.
What each format offers in practice
- An XML sitemap tells crawlers that a URL exists, when it was last modified, and how often it is updated. This helps with indexing but has no effect on the visitor experience.
- An HTML sitemap brings together links to every article on a page accessible from the footer or menu, allowing readers to scan the entire blog in seconds.
- Used together, the two formats address both sides of the problem: discovery by search engines and direct access for human readers.
Accessibility and WCAG: the sitemap as an additional navigation path
WCAG 2.2, published by the W3C in October 2023, requires that a page be findable through multiple means. A navigation menu alone isn’t enough: combining an internal search engine, a sitemap, and category-based navigation meets this requirement.
For a blog, this criterion is more than theoretical. A visually impaired reader using a screen reader can navigate the HTML sitemap as a structured list of links. Every article can be reached in just a few keystrokes, without relying on pagination or a visual carousel.
A sitemap also benefits visitors who land directly on an article through a search engine. These readers haven’t seen the homepage or the categories. Breadcrumbs show them where the article sits in the hierarchy, but the sitemap gives them access to the entire blog, not just the section they’re currently in.
Limitations of an HTML sitemap for a large blog
A sitemap listing several hundred links on a single page can be difficult to read. Beyond a certain size, the page itself becomes hard to navigate, partly negating its benefits.
Organizing links by category or publication year helps address this problem, but doesn’t eliminate it entirely. Some blogs split their sitemap across multiple pages, one for each section, to keep the number of links per page manageable.
Another point to keep in mind: an HTML sitemap doesn’t replace internal linking. An article linked from other blog posts (through contextual links in the body text) will always be easier to find than one that appears only in the sitemap. Internal linking remains the primary navigation tool on a blog, with the sitemap providing backup for content that falls outside those links.
When an HTML sitemap isn’t enough
- Articles with titles that don’t clearly describe their subject can still be hard to spot in a long list of links, even when organized by category.
- Multimedia content (videos, infographics) isn’t always well represented in a text-based sitemap, which can hide some of the blog’s richness.
- A sitemap that isn’t updated after every new post creates a gap between the actual content and what readers see, undermining their trust in the page.
An HTML sitemap for a blog isn’t a magic indexing tool or a substitute for a well-designed navigation structure. Its value lies in a specific role: ensuring that a motivated reader can always find an article, even an old one or one with few links pointing to it, by browsing a single page. For blogs that publish regularly, this safety-net function alone makes it worth setting one up.
