How do I find the sitemap of a website?

Check three places in order. First: the conventional location at https://example.com/sitemap.xml works for most sites. Second: open /robots.txt and look for a line that starts with Sitemap: — this is the authoritative reference, and many sites declare multiple sitemaps there. Third: probe common variants — /sitemap_index.xml, /sitemap-index.xml, /wp-sitemap.xml (WordPress), /sitemap1.xml. xmlsitemapmaker.com's sitemap checker tool automates all of this: enter a domain and it parses robots.txt, probes 8 common paths in parallel and content-sniffs each candidate to confirm it really is a sitemap. If none exist, the site genuinely doesn't publish one — use the URL generator to crawl and build a sitemap from the homepage.
