SEO Glossary
What is Sitemap?
A sitemap is a file (usually XML) that lists all important pages on a website, helping search engines discover, crawl, and index content more efficiently. Think of it as a roadmap for search engine bots.
Sitemaps are especially important for large sites, new sites, and sites with poor internal linking.

XML vs HTML sitemaps
XML Sitemap - A file designed for search engines listing URLs with metadata (last modified date, change frequency, priority). Located at yoursite.com/sitemap.xml.
HTML Sitemap - A user-facing page on your website that lists links to important pages, organized by category. Helps both users and search engines navigate.
XML sitemaps are essential for SEO. HTML sitemaps are optional but can improve user experience and internal linking.
