An XML sitemap is one or more XML files, the purpose of which is exactly the opposite of robots.txt: your store’s XML sitemap informs search engines about the URLs on your store website that are available for crawling. To enable search engines to crawl your website better, we strongly recommend submitting your store’s XML sitemap to search engines via the inclusion of the XML sitemap URL into robots.txt or manual submission of the URL directly to your chosen search engine.
