According to the <a href=\"https:\/\/www.sitemaps.org\/protocol.html\">Sitemaps.org protocol<\/a>, any single <a href=\"..\/SITEMAP\/\">SITEMAP<\/a> is restricted to 50,000 URLs or 50MB in size. To circumvent these limitations, developers implement a <a href=\"..\/SITEMAP-INDEX\/\">SITEMAP-INDEX<\/a> to point <a href=\"..\/SEARCH-ENGINE\/\">SEARCH-ENGINE<\/a> bots toward multiple individual sitemap files.<\/p><p>For platforms relying heavily on <a href=\"..\/SEARCH-ENGINE-OPTIMIZATION\/\">SEARCH-ENGINE-OPTIMIZATION<\/a>, such as <a href=\"..\/E-COMMERCE\/\">E-COMMERCE<\/a> sites or large <a href=\"..\/DATABASE\/\">DATABASE<\/a> driven portals, the index file is critical. It allows tools like <a href=\"..\/GOOGLE-SEARCH-CONSOLE\/\">GOOGLE-SEARCH-CONSOLE<\/a> and <a href=\"..\/BING-WEBMASTER-TOOLS\/\">BING-WEBMASTER-TOOLS<\/a> to efficiently map the site's <a href=\"..\/INFORMATION-ARCHITECTURE\/\">INFORMATION-ARCHITECTURE<\/a>. Instead of submitting dozens of individual files, the administrator submits one <a href=\"..\/SITEMAP-INDEX\/\">SITEMAP-INDEX<\/a>.<\/p><p>Technically, the index file uses the <code>&lt;sitemapindex&gt;<\/code> tag as its root, containing several <code>&lt;sitemap&gt;<\/code> nodes. Each node includes a <code>&lt;loc&gt;<\/code> tag specifying the URL of a sub-sitemap. As noted by <a href=\"https:\/\/developers.google.com\/search\/docs\/crawling-indexing\/sitemaps\/overview\">Google Search Central<\/a>, using an index is the best practice for managing large-scale <a href=\"..\/CRAWLING\/\">CRAWLING<\/a> budgets.<\/p><ul><li><a href=\"..\/XML-SITEMAP\/\">XML-SITEMAP<\/a><\/li><li><a href=\"..\/ROBOTS-TXT\/\">ROBOTS-TXT<\/a><\/li><li><a href=\"..\/SEARCH-ENGINE-OPTIMIZATION\/\">SEARCH-ENGINE-OPTIMIZATION<\/a><\/li><li><a href=\"..\/CRAWLING-AND-INDEXING\/\">CRAWLING-AND-INDEXING<\/a><\/li><\/ul>",
