站点地图检查工具

分析任意XML站点地图：URL数量、lastmod覆盖率以及站点地图索引结构。

如何使用本工具

1
Paste the full URL of your XML sitemap (for example https://example.com/sitemap.xml) into the input field.
2
Run the tool — our server fetches the file over HTTPS (falling back to HTTP) and parses it as XML.
3
Read the summary cards: detected Type, URL count, sub-sitemap count, and number of lastmod entries.
4
Scan the listed sub-sitemaps and the first 200 URLs to confirm the structure looks right.

XML站点地图会告诉搜索引擎要抓取哪些URL以及抓取的频率。它们并非严格必需，但有助于内容被发现，尤其是对于新建和大型网站。本检查工具会分析任意站点地图或站点地图索引，统计URL数量，并展示lastmod的覆盖率。请在Google Search Console中提交你的站点地图URL以便进行跟踪。

Confirm a newly generated sitemap actually contains every URL you expected before submitting it in Google Search Console.
Check whether a site uses a flat urlset or a sitemap index, and grab the list of child sitemap URLs to inspect each one.
Audit lastmod coverage by comparing the lastmod-entry count against the total URL count to spot missing change dates.
Spot-check a competitor's public sitemap to gauge how many indexable URLs their site exposes.
Verify that a sitemap moved to a new domain or path still returns valid XML after a migration or redirect.
Debug why search engines may not be picking up pages by confirming the expected URLs appear in the first 200 listed entries.

什么是站点地图索引？▼

一个链接到其他站点地图的站点地图。当你在单个站点地图中拥有超过50000个URL或超过50MB时，就需要它。

每个URL都必须有lastmod吗？▼

是的：它能帮助Google优先重新抓取那些确实发生了变化的页面。
