AI Overviews对于谷歌SEO优化的影响是什么?
谷歌发布了关于其新的AI Overviews搜索功能的新文档,该功能可概括搜索查询的答案,并链接到可以找到更多信息的网页。新文档提供了有关新功能如何工作以及出版商和搜索引擎优化人员应注意事项的重要信息。
触发AI Overviews因素
当用户的意图是快速了解信息,尤其是当信息需求与任务相关联时,AI Overviews就会显示出来。
“AI Overviews appear in Google Search results when our systems determine…when you want to quickly understand information from a range of sources,including information from across the web and Google’s Knowledge Graph.”
在文件的另一部分,它将触发器与基于任务的信息需求联系起来:
“…and use the information they find to advance their tasks.”
AI Overviews链接到哪些网站?
一个需要考虑的重要事实是,AI Overviews是由用户快速了解某事物的需求触发的,但这并不意味着只有信息需求的查询才会触发新的搜索功能。谷歌的文档明确指出,将从AI Overviews链接中受益的网站类型包括"创作者"(这意味着视频创作者)、电子商务商店和其他企业。这意味着将从AI概述中受益的网站远不止信息网站。
新文档列出了可以从AI Overviews中获得链接的网站类型:
“This allows people to dig deeper and discover a diverse range of content from publishers,creators,retailers,businesses,and more,and use the information they find to advance their tasks.”
AI Overviews的信息来源
AI Overviews显示了来自网络和知识图谱的信息。目前,在添加大量新数据时,大型语言模型需要完全从头开始重新训练。这意味着被选中在Overviews功能中显示的网站都是从谷歌的标准搜索索引中挑选出来的,这反过来又意味着谷歌可能正在使用检索增强生成(RAG)技术。
RAG是一个介于大型语言模型和LLM外部信息数据库之间的系统。外部数据库可以是特定的知识,如组织人力资源政策的全部内容,也可以是搜索索引。它是一个补充信息源,可用于重复检查LLM提供的信息,或显示在哪里可以阅读到更多关于所回答问题的信息。
文章开头引用的部分指出,AI Overviews引用了来自网络和知识图谱的资料:
“AI Overviews appear in Google Search results when our systems determine…when you want to quickly understand information from a range of sources,including information from across the web and Google’s Knowledge Graph.”
自动纳入对SEO的意义
列入AI Overviews是自动的,出版商或搜索引擎优化人员不需要做任何与AI Overviews有关的具体工作。谷歌的文档指出,要想在AI Overviews中获得排名,只需遵循他们的常规搜索排名指南即可。谷歌的"系统"决定哪些网站会被选中显示在AI Overviews中。
所有声明似乎都证实,新的概述功能的数据来源于常规搜索索引。谷歌有可能专门为AI Overviews过滤了搜索索引,但我想不出谷歌这样做的理由。
所有表明自动包含的声明都表明,谷歌很可能使用常规搜索索引:
“No action is needed for publishers to benefit from AI Overviews.”
“AI Overviews show links to resources that support the information in the snapshot,and explore the topic further.”
“…diverse range of content from publishers,creators,retailers,businesses,and more…”
“To rank in AI Overviews,publishers only need to follow the Google Search Essentials guide.
“Google’s systems automatically determine which links appear.There is nothing special for creators to do to be considered other than to follow our regular guidance for appearing in search,as covered in Google Search Essentials.”
从主题的角度思考
很明显,查询和文件中的关键词和同义词发挥着作用。但在我看来,它们在SEO中的作用过于重要。搜索引擎可以通过多种方式对文档进行注释,以便将网页与主题相匹配,比如谷歌搜索专家Martin Splitt所说的中心注释。谷歌使用中心注释来标注网页的内容。
语义注释
这种注释将网页内容与概念联系起来,从而为非结构化文档提供结构。每个网页都是非结构化数据,因此搜索引擎必须对此加以理解。语义注释就是一种方法。
至少从2015年起,谷歌就开始将网页与概念进行匹配。谷歌关于其云产品的网页介绍了他们如何将神经匹配集成到搜索引擎中,以便用固有的主题来注释网页内容。
谷歌是这样说它如何将网页与概念相匹配的:
“Google Search started incorporating semantic search in 2015,with the introduction of noteworthy AI search innovations like deep learning ranking system RankBrain.This innovation was quickly followed with neural matching to improve the accuracy of document retrieval in Search.Neural matching allows a retrieval engine to learn the relationships between a query’s intentions and highly relevant documents,allowing Search to recognize the context of a query instead of the simple similarity search.
Neural matching helps us understand fuzzier representations of concepts in queries and pages,and match them to one another.It looks at an entire query or page rather than just keywords,developing a better understanding of the underlying concepts represented in them.”
近十年来,谷歌一直在做这项工作,将网页与概念进行匹配。谷歌关于人工智能概述的文档中还提到,根据主题显示网页链接是决定人工智能概述中网站排名的一部分。
下面是谷歌的解释:
“AI Overviews show links to resources that support the information in the snapshot,and explore the topic further.
…AI Overviews offer a preview of a topic or query based on a variety of sources,including web sources.”
谷歌对主题的关注由来已久,搜索引擎优化人员早就应该减少对关键字定位的控制,开始给主题定位一个机会,以丰富他们在谷歌搜索(包括AI Overviews)中展示内容的能力。
谷歌表示,其搜索要点文档中描述的用于在谷歌搜索中排名的优化方法与用于在谷歌概览中排名的优化方法相同。
这正是新文件中所说的:
“There is nothing special for creators to do to be considered other than to follow our regular guidance for appearing in search,as covered in Google Search Essentials.”
