全新漫遊器標記：indexifembed
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
2022 年 1 月 21 日，星期五
今天，我們推出了全新的漫遊器標記「indexifembedded」，讓您可以進一步控管系統將內容編入索引的情況。你可以透過 indexifembedded 標記讓 Google 知道，某項內容雖然透過 iframes 和類似的 HTML 標記嵌入到其他網頁，甚至該內容網頁設有 noindex 標記，您還是希望系統將該內容編入索引。
indexifembedded 標記所處理的這項常見問題，對於媒體發布商影響特別大：他們可能希望自家內容在嵌入到第三方網頁的情況下，可以納入索引中，但不一定想自行將自家媒體頁面編入索引中。他們不希望系統將媒體網頁編入索引，因此目前在這類網頁上使用了 noindex 標記。然而 noindex 標記也會防止系統建立索引時在其他網頁中嵌入該內容。
新的漫遊器標記 indexifembedded 用於搭配 noindex 標記運作，前提是這個含有 noindex 的網頁必須透過 iframe 或類似的 HTML 標記 (例如 object) 嵌入到其他網頁。舉例來說，如果 podcast.host.example/playpage?podcast=12345 同時含有 noindex 和 indexifembedded 標記，表示 Google 可以在建立索引時，將該網頁上代管的內容嵌入到 recipe.site.example/my-recipes.html 中。
如要限定您的內容只有在嵌入到其他網頁時才納入索引，請務必新增 indexifembedded 並搭配 noindex 標記。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 標頭中指定標記：
X-Robots-Tag: googlebot:noindex
X-Robots-Tag: googlebot:indexifembedded
...
OR
…
X-Robots-Tag: googlebot:noindex,indexifembedded
目前，只有 Google 支援 indexifembedded 標記。
希望這個新標記對您有幫助。如有任何問題或意見，歡迎前往 Twitter 和我們的說明論壇告訴我們。

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.
