Technical SEO & Web Infrastructure

사이트맵 인덱스

A sitemap index allows one submission, such as sitemap_index.xml, to point search engines to all component sitemaps. Accurate lastmod values help indicate which component files changed. For large e-commerce catalogs, splitting by category also makes missing index coverage easier to diagnose. This organization handles the 50,000-URL and 50 MB uncompressed limits of individual sitemap files without treating one giant file as the only option.

Business applications and impact#

Organizes discovery for very large e-commerce and media sites within sitemap size limits.

Implementation guidance and considerations#

Separate files by content type, such as sitemap-products.xml and sitemap-blog.xml, for targeted indexing diagnostics.

Code example#

<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <sitemap>
    <loc>https://example.com/sitemap-products.xml</loc>
    <lastmod>2026-09-20</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://example.com/sitemap-blog.xml</loc>
