What Is an HTML Sitemap?
An HTML sitemap is a single page that links to every other page on a site, written for people rather than for crawlers. It is the fastest way to see everything Physics Fundamentals holds — and it gives search engines a short path to every page from one place. The machine-readable version lives at /sitemap.xml.
