新的漫游器标记：indexifembedded

根据您的偏好保存内容并对其进行分类。

今天，我们推出了新的漫游器标记 indexifembedded，便于您在内容被编入索引方面有更多选择。借助 indexifembedded 标记，您可以告知 Google：当您的内容通过 iframes 和类似 HTML 标记嵌入到其他网页中时，您仍希望系统将其编入索引（即使内容页使用了 noindex 标记）。
indexifembedded 标记解决了尤其影响媒体内容发布者的常见问题：尽管他们可能希望自己的内容在嵌入到第三方网页中时被编入索引，但他们并不一定希望自己网站上的媒体内容页被编入索引。由于他们不希望媒体内容页被编入索引，因此目前针对此类网页使用了 noindex 标记。不过，noindex 标记在系统编制索引期间会同时阻碍内容被嵌入到其他网页中。
只有使用了 noindex 的媒体内容页通过 iframe 或类似 HTML 标记（例如 object）嵌入到其他网页中时，新的漫游器标记 indexifembedded 才能与 noindex 标记搭配使用。
例如，如果 podcast.host.example/playpage?podcast=12345 同时使用了 noindex 和 indexifembedded 标记，则表示 Google 可以在编制索引期间将该网页上托管的内容嵌入到 recipe.site.example/my-recipes.html 中。
若要让内容仅在嵌入到其他网页中时才被编入索引，请务必同时添加 indexifembedded 与 noindex 标记。例如：
<meta name="googlebot" content="noindex" />
<meta name="googlebot" content="indexifembedded" />
<!-- OR -->
<meta name="googlebot" content="noindex,indexifembedded" />
或者，您也可以在 HTTP 标头中指定此标记：
X-Robots-Tag: googlebot:noindex
X-Robots-Tag: googlebot:indexifembedded
...
OR
…
X-Robots-Tag: googlebot:noindex,indexifembedded
目前，只有 Google 支持 indexifembedded 标记。
希望这个新标记能对您有所帮助。如果您有任何疑问或意见，请通过 Twitter 和帮助论坛与我们联系。

When a page with `noindex` is embedded via `iframe` or similar tags, `indexifembedded` allows Google to index the content during indexing. This addresses media publishers' need to prevent indexing of their media pages while enabling indexing of embedded content on third-party sites. Implement it with `\u003cmeta\u003e` tags or HTTP headers, using `noindex` and `indexifembedded` together. Currently, only Google supports `indexifembedded`.\n"],null,["# New robots tag: indexifembedded\n\nFriday, January 21, 2022\n\n\nToday, we're introducing a new robots tag,\n[`indexifembedded`](/search/docs/crawling-indexing/robots-meta-tag#indexifembedded),\nthat brings you more control over when your content is indexed. With the\n`indexifembedded` tag, you can tell Google you'd still like your content indexed when\nit's embedded through\n[`iframes`](https://developer.mozilla.org/docs/Web/HTML/Element/iframe)\nand similar HTML tags in other pages, even when the content page has the `noindex` tag.\n\n\nThe `indexifembedded` tag addresses a common issue that especially affects media\npublishers: while they may want their content indexed when it's embedded on third-party pages,\nthey don't necessarily want their media pages indexed on their own. Because they don't want the\nmedia pages indexed, they currently use a `noindex` tag in such pages. However, the\n`noindex` tag also prevents embedding the content in other pages during indexing.\n\n\nThe new robots tag, `indexifembedded`, works in combination with the\n`noindex` tag only when the page with `noindex` is embedded into another\npage through an `iframe` or similar HTML tag, like\n[`object`](https://developer.mozilla.org/docs/Web/HTML/Element/object).\nFor example, if\n`podcast.host.example/playpage?podcast=12345` has both the `noindex` and\n`indexifembedded` tag, it means Google can embed the content hosted on that page in\n`recipe.site.example/my-recipes.html` during indexing.\n\n\nTo enable your content to be indexed only when it's embedded on other pages, make sure to add\n`indexifembedded` in combination with the `noindex` tag. For example: \n\n```ecl\n\u003cmeta name=\"googlebot\" content=\"noindex\" /\u003e\n\u003cmeta name=\"googlebot\" content=\"indexifembedded\" /\u003e\n\u003c!-- OR --\u003e\n\u003cmeta name=\"googlebot\" content=\"noindex,indexifembedded\" /\u003e\n```\n\n\nAlternatively, you can specify the tag in the HTTP header: \n\n```\nX-Robots-Tag: googlebot:noindex\nX-Robots-Tag: googlebot:indexifembedded\n...\nOR\n…\nX-Robots-Tag: googlebot:noindex,indexifembedded\n```\n\nPresently, only Google supports the `indexifembedded` tag.\n\n\nWe hope you find this new tag useful.
