FAQ

What sitemap problems should I check first?

Duplicate URLs, wrong domains, missing localized alternates, stale or noisy lastmod values, and URLs blocked by robots.txt are the first things to inspect.

Should every deploy update lastmod?

No. lastmod should reflect meaningful content changes. Updating every URL on every deploy can send noisy signals.

Can a sitemap force indexing?

No. It helps discovery. Pages still need crawlable URLs, useful content, canonical consistency, and internal links.

Sitemap XML Viewer previews URL entries, sitemap indexes, duplicate loc values, lastmod quality, and hreflang alternates.

It is useful for multilingual tool sites where hundreds of generated pages can make sitemap mistakes hard to spot by reading XML.

Use it before submitting a sitemap to search engines, after adding batches of tools or blog posts, and when debugging indexing coverage.

Demo: review a multilingual sitemap batch

A tool site can generate many URLs quickly. Sitemap preview helps confirm the batch matches the actual site architecture before search engines discover it.

  • Count URLs by locale and compare with generated routes.
  • Check xhtml:link alternates when hreflang is included in the sitemap.
  • Review lastmod dates for content quality instead of build noise.

  <lastmod>2026-06-17</lastmod>
  <xhtml:link rel="alternate" hreflang="zh-CN" href="https://diagrampreview.com/zh-CN/mermaid-preview" />
</url>

SEO debugging: what to inspect before index submission

Large multilingual sites need sitemap review beyond “is the XML valid”. The useful questions are whether every canonical URL appears once, whether lastmod is meaningful, and whether locale alternates line up with the live routes.

  • Count URLs by locale to catch missing route generation.
  • Look for duplicated loc values caused by trailing slash or locale redirects.
  • Check lastmod only when it reflects real content changes, not every build.
