HTML Sitemap
A user-facing page listing links to key pages on a site — helping both users navigate large sites and Googlebot discover pages that may be buried deep in the navigation.
Definition
An HTML sitemap is a regular webpage (typically at `/sitemap` or `/sitemap.html`) that contains human-readable links to the important pages on a website, organised by section. It is distinct from an XML sitemap (`/sitemap.xml`) which is machine-readable and submitted to search engines. An HTML sitemap serves two purposes: (1) user navigation — on large sites, an HTML sitemap helps users find content not reachable through the main navigation; (2) crawler discovery — Googlebot follows links from HTML pages, so an HTML sitemap linked from the footer provides an additional path for Googlebot to discover pages buried deep in the site structure. It should link to every major section and key landing page without being an exhaustive list of every URL.
Why it matters for SEO
HTML sitemaps matter most on large content sites and e-commerce sites where main navigation surfaces only a fraction of total content. For sites with deep page hierarchies — content 4+ clicks from the homepage — an HTML sitemap provides an additional crawl path that reduces effective click depth for buried pages. Google has stated that HTML sitemaps are a useful crawl discovery mechanism for large sites, as they give crawlers a "map" from a single well-linked page to many interior pages. For smaller sites (under 100 pages), an HTML sitemap adds marginal value beyond what the footer and blog index already provide.
How DeepSEOAnalysis checks this
The audit checks: whether the site has an HTML sitemap (by looking for links to `/sitemap` or `/sitemap-html` in the footer or navigation), whether the HTML sitemap page is linked from the footer (ensuring Googlebot finds it from every page), and whether it links to all major sections. An absent HTML sitemap on a site with 50+ pages and deep hierarchies is flagged as a crawl accessibility recommendation.
