使用站点地图索引文件管理站点地图
如果您的站点地图超过了大小上限,则需要将较大的站点地图拆分成多个站点地图,让每个新站点地图都小于大小上限。拆分站点地图后,您可以使用站点地图索引文件这种方式同时提交多个站点地图。
站点地图索引最佳实践
XML 格式的站点地图索引文件与 XML 格式的站点地图文件非常相似,前者由站点地图协议定义。
这意味着,所有站点地图要求同样适用于站点地图索引文件。
引用的站点地图必须与站点地图索引文件在同一个网站上托管。如果您设置了跨网站提交功能,则可免除此要求。
站点地图索引文件中引用的站点地图必须与站点地图索引文件位于同一目录中,或者位于网站层次结构中的更低一级目录中。例如,如果站点地图索引文件位于 https://example.com/public/sitemap_index.xml
,它只能包含位于相同或更深目录中的站点地图,如 https://example.com/public/shared/...
。
您最多可为 Search Console 账号中的每个网站提交 500 个站点地图索引文件。
站点地图索引示例
以下示例是一个 XML 格式的站点地图索引,其中列出了两个站点地图:
<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<sitemap>
<loc>https://www.example.com/sitemap1.xml.gz</loc>
<lastmod>2024-08-15</lastmod>
</sitemap>
<sitemap>
<loc>https://www.example.com/sitemap2.xml.gz</loc>
<lastmod>2022-06-05</lastmod>
</sitemap>
</sitemapindex>
站点地图索引引用
站点地图索引标记由与通用站点地图相同的命名空间定义:
http://www.sitemaps.org/schemas/sitemap/0.9
为确保 Google 能够使用您的站点地图索引,您必须使用以下必需的标记:
必需的标记 |
sitemapindex |
XML 树的根标记。它包含所有其他标记。 |
sitemap |
文件中列出的每个站点地图的父标记。它是 sitemapindex 标记的唯一直接子级。
|
loc |
站点地图的位置(网址)。它是 sitemap 标记的子级。一个站点地图索引文件最多可以包含 50,000 个 loc 标记。
|
此外,以下可选标记可能有助于 Google 安排何时抓取您的站点地图:
可选标记 |
lastmod |
标识修改相应站点地图文件的时间。它可以是 sitemap 标记的子级。lastmod 标记的值必须采用 W3C 日期时间格式。

Once you've split up your sitemap, you can use a sitemap index file\nas a way to submit many sitemaps at once.\n\nSitemap index best practices\n----------------------------\n\n\nThe XML format of a sitemap index file is very\nsimilar to the XML format of a sitemap file, and it's defined by the\n[Sitemap Protocol](https://www.sitemaps.org/protocol.html#index).\nThis means that all the sitemap requirements apply to sitemap index files also.\n\n\nThe referenced sitemaps must be hosted on the same site as your sitemap index file. This\nrequirement is waived if you set up\n[cross-site submission](/search/docs/crawling-indexing/sitemaps/build-sitemap#cross-submit).\n\n\nSitemaps that are referenced in the sitemap index file must be in the same\ndirectory as the sitemap index file, or lower in the site hierarchy. For example, if the\nsitemap index file is at `https://example.com/public/sitemap_index.xml`, it can\nonly contain sitemaps that are in the same or deeper directory, like\n`https://example.com/public/shared/...`.\n\n\nYou can submit up to 500 sitemap index files for each site in your Search Console account.\n\nExample sitemap index\n---------------------\n\n\nThe following example shows a sitemap index in XML format that lists two sitemaps: \n\n```world-of-warcraft-toc\n\u003c?xml version=\"1.0\" encoding=\"UTF-8\"?\u003e\n\u003csitemapindex xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\"\u003e\n \u003csitemap\u003e\n \u003cloc\u003ehttps://www.example.com/sitemap1.xml.gz\u003c/loc\u003e\n \u003clastmod\u003e2024-08-15\u003c/lastmod\u003e\n \u003c/sitemap\u003e\n \u003csitemap\u003e\n \u003cloc\u003ehttps://www.example.com/sitemap2.xml.gz\u003c/loc\u003e\n \u003clastmod\u003e2022-06-05\u003c/lastmod\u003e\n \u003c/sitemap\u003e\n\u003c/sitemapindex\u003e\n```\n\nSitemap index reference\n-----------------------\n\n\nThe sitemap index tags are defined by the same namespace as generic sitemaps:\n[`http://www.sitemaps.org/schemas/sitemap/0.9`](http://www.sitemaps.org/schemas/sitemap/0.9)\n\nTo make sure Google can use your sitemap index, you must use the following required tags:\n\n| Required tags ||\n|----------------|------------------------------------------------------------------------------------------------------------------------------|\n| `sitemapindex` | The root tag of the XML tree. It contains all the other tags. |\n| `sitemap` | The parent tag for each sitemap listed in the file. It's the only direct child of the `sitemapindex` tag. |\n| `loc` | The location (URL) of the sitemap. It's a child of the `sitemap` tag. A sitemap index file may have up to 50,000 `loc` tags. |\n\n\nAdditionally, the following optional tags may help Google schedule your sitemaps for crawling:\n\n| Optional tags ||\n|-----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `lastmod` | Identifies the time that the corresponding sitemap file was modified. It can be a child of a `sitemap` tag. The value for the `lastmod` tag must be in [W3C Datetime format](https://www.w3.org/TR/NOTE-datetime). |\n\nAdditional resources\n--------------------\n\n\nWant to learn more?
