学习视频(LearningResourceVideoObjectClip)结构化数据

学习视频富媒体搜索结果示例

Google 搜索是学生和教师发现并观看教育性视频的切入点。有了您通过结构化数据明确提供的特定于学习的信息(例如视频中介绍的教育水平以及概念和技能),Google 可以更好地了解您的视频内容并提供更出色的体验,从而帮助学习者找到合适的内容。

此外,学习视频结构化数据还可以启用与学习视频相关的信息条状标签,例如教育水平和视频类型(例如概览或解决方案视频)。

在用户点按视频前,信息条状标签如何显示在学习视频下方 在用户点按视频后,信息条状标签如何显示在学习视频上方

功能可用性

在所有可以使用 Google 搜索的区域,学习视频富媒体搜索结果均以英语提供。仅当在桌面设备和移动设备上搜索学术学习内容时,才能使用此功能。

如何添加结构化数据

结构化数据是一种提供网页相关信息并对网页内容进行分类的标准化格式。如果您不熟悉结构化数据,可以详细了解结构化数据的运作方式

下面概述了如何构建、测试和发布结构化数据。如需获得向网页添加结构化数据的分步指南,请查看结构化数据 Codelab

  1. 添加必要属性。根据您使用的格式,了解在网页上的什么位置插入结构化数据
  2. 遵循指南
  3. 使用富媒体搜索结果测试验证您的代码,并修复所有严重错误。此外,您还可以考虑修正该工具中可能会标记的任何非严重问题,因为这些这样有助于提升结构化数据的质量(不过,要使内容能够显示为富媒体搜索结果,并非必须这么做)。
  4. 部署一些包含您的结构化数据的网页,然后使用网址检查工具测试 Google 看到的网页样貌。请确保您的网页可供 Google 访问,不会因 robots.txt 文件、noindex 标记或登录要求而被屏蔽。如果网页看起来没有问题,您可以请求 Google 重新抓取您的网址
  5. 为了让 Google 随时了解日后发生的更改,我们建议您提交站点地图Search Console Sitemap API 可以帮助您自动执行此操作。

指南

若想让您的网页可显示为学习视频富媒体搜索结果,您必须遵循以下指南:

技术指南

  • 除了学习视频标记之外,您还必须添加 VideoObject 的必需属性和建议属性
  • 视频必须是公开的,无需订阅即可观看。
  • 视频总时长必须至少为 30 秒。
  • 学习视频标记必须添加到能让用户观看视频的网页中。将用户引导至无法观看视频的网页会导致糟糕的用户体验。

结构化数据类型定义

如需了解 VideoObjectLearningResource 的完整定义,请访问 schema.org VideoObjectLearningResource

若要使您的内容能够显示为学习视频富媒体搜索结果,您必须为其添加必要属性。您还可添加建议属性,以便添加与您内容相关的更多信息,进而优化用户体验。

学习视频 [VideoObject, LearningResource]

学习视频标记旨在让用户更清楚地了解该视频的教育内容。此标记中可以包含视频中介绍的各种概念和技能的相关信息。

对学习视频使用 [VideoObject, LearningResource] 类型。除了 VideoObject 的必要属性和建议属性之外,您还可以为学习视频添加以下属性。

必要属性
educationalAlignment

AlignmentObject

与内容相关的正式标准代码、课程或考试。仅当您的内容符合特定标准或考试要求时,才使用此属性。否则,只能使用 educationalLevel 属性。如果您添加了 educationalAlignment 属性,请添加以下属性(如适用):

虽然您可以提供多个 educationalAlignment 值,但并不保证这些值都会用于学习视频功能。如果提供了多个值,并且相应功能只能使用一个 educationalAlignment 值,则该功能会使用您提供的第一个值。

示例

"educationalAlignment":
            {
              "@type": "AlignmentObject",
              "educationalFramework": "Common Core",
              "targetName": "CCSS.MATH.CONTENT.7.SP.B.4",
              "targetUrl": "https://www.corestandards.org/Math/Content/7/SP/B/4/"
            }
"educationalAlignment":
            {
              "@type": "AlignmentObject",
              "educationalFramework": "NCERT",
              "targetUrl": "https://ncert.nic.in/"
            }
educationalLevel

Text

视频的目标教育水平。将目标教育水平设置为适用于特定国家/地区的值或通用值。

适用于特定国家/地区的值

每个国家/地区都有自己的学术体系。根据视频的适用国家/地区,将 educationalLevel 设置为其中一个受支持的等级值。

使用 Search Console 监控富媒体搜索结果

Search Console 是一款工具,可帮助您监控网页在 Google 搜索结果中的显示效果。即使没有注册 Search Console,您的网页也可能会显示在 Google 搜索结果中,但注册 Search Console 能够帮助您了解 Google 如何查看您的网站并做出相应的改进。建议您在以下情况下查看 Search Console:

  1. 首次部署结构化数据后
  2. 发布新模板或更新代码后
  3. 定期分析流量时

首次部署结构化数据后

等 Google 将网页编入索引后,请在相关的富媒体搜索结果状态报告中查看是否存在问题。 理想情况下,有效项目数量会增加,而无效项目数量不会增加。如果您发现结构化数据存在问题,请执行以下操作:

  1. 修正无效项目
  2. 检查实际网址,核实问题是否仍然存在。
  3. 使用状态报告请求验证

发布新模板或更新代码后

如果对网站进行重大更改,请监控结构化数据无效项目的增幅。
  • 如果您发现无效项目增多了,可能是因为您推出的某个新模板无法正常工作,或者您的网站以一种新的错误方式与现有模板交互。
  • 如果您发现有效项目减少了(但无效项目的增加情况并不对应),可能是因为您的网页中未再嵌入结构化数据。请通过网址检查工具了解导致此问题的原因。

定期分析流量时

请使用效果报告分析您的 Google 搜索流量。数据将显示您的网页在 Google 搜索结果中显示为富媒体搜索结果的频率、用户点击该网页的频率以及网页在搜索结果中的平均排名。您还可以使用 Search Console API 自动提取这些结果。

问题排查

如果您在实施或调试结构化数据时遇到问题,请查看下面列出的一些实用资源。

  • 如果您使用了内容管理系统 (CMS) 或其他人负责管理您的网站,请向其寻求帮助。请务必向其转发列明问题细节的任何 Search Console 消息。
  • Google 不能保证使用结构化数据的功能一定会显示在搜索结果中。如需查看导致 Google 无法将您的内容显示为富媒体搜索结果的各种常见原因,请参阅结构化数据常规指南
  • 您的结构化数据可能存在错误。请参阅结构化数据错误列表
  • 如果您的网页受到结构化数据手动操作的影响,其中的结构化数据将会被忽略(但该网页仍可能会出现在 Google 搜索结果中)。如需修正结构化数据问题,请使用“人工处置措施”报告
  • 再次查看相关指南,确认您的内容是否未遵循指南。问题可能是因为出现垃圾内容或使用垃圾标记导致的。不过,问题可能不是语法问题,因此富媒体搜索结果测试无法识别这些问题。
  • 针对富媒体搜索结果缺失/富媒体搜索结果总数下降进行问题排查
  • 请等待一段时间,以便 Google 重新抓取您的网页并重新将其编入索引。请注意,网页发布后,Google 可能需要几天时间才会找到和抓取该网页。有关抓取和索引编制的常见问题,请参阅 Google 搜索抓取和索引编制常见问题解答
  • Google 搜索中心论坛中发帖提问。

内容与结构化数据不匹配

导致问题的原因:网页包含的内容与该网页上的结构化数据不匹配。例如,该网页上某个视频的标题与为 name 属性列出的值不匹配。此外,该网页上也可能存在垃圾内容,例如点击诱饵类的标题和说明,或者标记不代表实际视频。您可能收到了以下 Search Console 消息:“违反了结构化数据政策 - 我们发现网页上的内容与网页上的结构化数据不同。”

解决问题

  1. 确认结构化数据与网页上的实际内容一致。
  2. 使用网址检查工具确保相关内容在呈现的网页上可见(呈现的网页是指向 Google 呈现的网页)。
  3. 解决问题后,请提交网站以供重新审核
