このガイドでは、サイト所有者の視点から、Google 検索での AI による概要や AI モードなどの AI 機能の仕組みと、コンテンツを AI エクスペリエンスに反映させる方法について説明します。
検索での AI 機能の仕組み
通常の検索と同様に、AI による概要や AI モードなどの AI 機能は、関連リンクを表示することで、ユーザーが求める情報をすばやく確実に見つけられるようにします。また、これまで見つけられなかったコンテンツを発見する手助けにもなります。これらの機能により、幅広いタイプのサイトが検索結果に表示されやすくなります。
AI による概要はユーザーが複雑なトピックや質問の要点をすばやく把握できるようにし、詳細を確認するための関連リンクも提供します。これは、通常の検索結果以上の価値を提供できるクエリで表示されるように設計されています。AI による概要を使用して、多様なウェブサイトにアクセスし、複雑な質問に対する答えを探すユーザーが増えています。
AI モードは、さらなる調査、根拠、複雑な比較が必要とされるクエリで特に便利な機能です。ユーザーは、新しい概念の理解やオプションの比較など、これまで複数回の検索を必要とした複雑な質問を一度に行えます。さらに、AI による総合的な回答と、参考になるウェブサイトへのリンクを得られます。
AI による概要と AI モードは、「クエリ ファンアウト」手法を使う場合があります。これは、関連する複数のサブトピックやデータソースに対して検索を実行し、それをもとに回答を組み立てる手法です。回答を生成する際に、Google の高度なモデルは裏付けとなる関連ウェブページを特定します。これにより、従来の検索よりも幅広く有益なリンクを表示でき、情報探索に新たな可能性を開きます。
AI モードと AI による概要では、使用するモデルや手法が異なる場合があるため、表示される回答やリンクの内容にも違いがあります。AI による概要は、従来の検索結果に対して付加価値があるとシステムが判断した場合にのみ表示されるため、通常はトリガーされません。
プレビュー コントロールに問題がなく、Googlebot が認識できるようになっていることを確認してください。正しく実装されているかどうかをテストするには、URL 検査ツールを使用して、ページのクロール中に Googlebot が取得した HTML を確認します。
Google が再クロールしてプレビュー コントロールの変更を処理する時間を考慮してください。Google のシステムは、そのページをどのくらいの頻度で更新する必要があるかを判断します。その頻度に応じて、クロールには数日から数か月かかる場合があります。変更を加えた場合は、ページの再クロールを Google にリクエストして変更を伝えられます。

These features offer unique opportunities for more types of sites to appear.\n\n\n**AI Overviews** help people get to the gist of a complicated topic or question more\nquickly, and provide a jumping off point to explore links to learn more. They were designed to\nshow up on queries where they can add additional benefits beyond what people might already get on\nSearch. With AI Overviews, people have been visiting a greater diversity of websites for help with\nmore complex questions.\n\n\n**AI Mode** is particularly helpful for queries where further exploration, reasoning,\nor complex comparisons are needed. People can ask nuanced questions that might have previously\ntaken multiple searches --- from exploring a new concept, to comparing options, and beyond --- and\nget a comprehensive AI-powered response with links to supporting websites. \n\n\nBoth AI Overviews and AI Mode may use a \"query fan-out\" technique --- issuing multiple related\nsearches across subtopics and data sources --- to develop a response. While responses are being\ngenerated, our advanced models identify more supporting web pages, allowing us to\n**display a wider and more diverse set of helpful links** associated with the\nresponse than with a classic web search, enabling new opportunities for exploration.\n\n\nAI Mode and AI Overviews may use different models and techniques, so the set of responses and\nlinks they show will vary. AI Overviews are only shown when our systems determine that it is\nadditive to classic Search, and as such, often don't trigger.\n\nHow to appear in AI features\n----------------------------\n\n\nYou can apply the same [foundational SEO best practices](/search/docs/essentials) for\nAI features as you do for Google Search overall: making sure the page meets the\n[technical requirements for Google Search](/search/docs/essentials/technical),\nfollowing [Search policies](https://support.google.com/websearch/answer/10622781),\nand focusing on the [key best practices](/search/docs/essentials#key-best-practices),\nsuch as [creating helpful, reliable, people-first content](/search/docs/fundamentals/creating-helpful-content).\n\n### Technical requirements for appearing in AI features\n\n\nTo be eligible to be shown as a supporting link in AI Overviews or AI Mode, a page must be indexed\nand eligible to be shown in Google Search with a snippet, fulfilling the\n[Search technical requirements](/search/docs/essentials/technical). There are no\nadditional technical requirements.\n| Just because a page meets all requirements, best practices, and complies with the policies, doesn't mean that Google will crawl, index, or serve its content. Indexing and serving isn't guaranteed. Learn more about [How Search Works](/search/docs/fundamentals/how-search-works).\n\n### SEO best practices\n\n\nWhile specific optimization isn't required for AI Overviews and AI Mode, all existing\n[SEO fundamentals](/search/docs/fundamentals/seo-starter-guide) continue to be\nworthwhile, for example:\n\n- Ensuring that crawling is allowed in robots.txt, and by any CDN or hosting infrastructure\n- Making your content easily findable through [internal links](/search/docs/crawling-indexing/links-crawlable#internal-links) on your website\n- Providing a great [page experience](/search/docs/appearance/page-experience) for users\n- Making sure that important content is available in textual form\n- Supporting your textual content with high-quality [images](/search/docs/appearance/google-images) and [videos](/search/docs/appearance/video), when applicable\n- Making sure your [structured data](/search/docs/appearance/structured-data/sd-policies) matches the visible text on the page\n- Checking that your [Merchant Center](https://support.google.com/merchants/answer/12159157) and [Business Profile](/search/docs/appearance/establish-business-details) information is up-to-date\n\n| You don't need to create new machine readable files, AI text files, or markup to appear in these features. There's also no special schema.org structured data that you need to add.\n\n\nTo discover and diagnose potential technical issues quickly, [verify your site\nin Search Console](https://support.google.com/webmasters/answer/9008080).\n\nMeasuring the performance of your site\n--------------------------------------\n\n\nJust like the rest of the search results page, sites appearing in AI features (such as AI Overviews\nand AI Mode) are included in the overall search traffic in\n[Search Console](https://search.google.com/search-console/about).\nIn particular, they're reported on in the [Performance report](https://support.google.com/webmasters/answer/7576553),\nwithin the [\"Web\" search type](https://support.google.com/webmasters/answer/7576553#by_search_type).\nLearn more about how [AI Overviews](https://support.google.com/webmasters/answer/7042828#ai-overviews&zippy=%2Ct%2Cai-overviews)\nand [AI Mode](https://support.google.com/webmasters/answer/7042828#ai-mode&zippy=%2Ct%2Cai-mode) are counted\ntowards the overall data in Search Console, how to\n[analyze traffic changes](/search/docs/monitor-debug/debugging-search-traffic-drops)\noverall, and how to [combine Search Console and Analytics data](/search/docs/monitor-debug/google-analytics-search-console).\n\n\nIn addition to Search Console, you could also track conversions and time spent on your site in\nother tools, such as Google Analytics. We've seen that when people click from search results\npages with AI Overviews, these clicks are higher quality (meaning, users are more likely to spend\nmore time on the site).\n\nControlling your content in AI features in Search\n-------------------------------------------------\n\n\nAI is built into Search and integral to how Search functions, which is why robots.txt directives\nfor [Googlebot](/search/docs/crawling-indexing/overview-google-crawlers) is the control\nfor site owners to manage access to how their sites are crawled for Search. To limit the\ninformation shown from your pages in Search, use [`nosnippet`,\n`data-nosnippet`, `max-snippet`](/search/docs/crawling-indexing/robots-meta-tag), or\n[`noindex`](/search/docs/crawling-indexing/block-indexing) controls.\n\n\nTo limit AI training and grounding in some of Google's other systems, read more\n[about Google-Extended](/search/docs/crawling-indexing/google-common-crawlers#google-extended).\n\n### Troubleshooting preview controls\n\n\nIf you implemented [preview controls](/search/docs/appearance/snippet#nosnippet) and\nyou're still seeing your content appear in AI features on Search, try the following steps:\n\n1. Make sure that the preview control is correct and visible to Googlebot. To test if your implementation is correct, use the [URL\n Inspection tool](https://support.google.com/webmasters/answer/9012289) to see the HTML that Googlebot received while crawling the page.\n2. Allow time for Google to recrawl and process the change in preview controls. Remember that crawling can take anywhere from several days to several months, depending on how often our systems determine a page needs to be refreshed. If you've made changes, you can [request\n that Google recrawl your pages](/search/docs/crawling-indexing/ask-google-to-recrawl).\n\n\nIf you tried the troubleshooting steps and still find issues, post in the\n[Google Search Central Help Community](https://support.google.com/webmasters/thread/227739087)."]]
