COVID-19 通知 (SpecialAnnouncement
) 结构化数据(Beta 版)
受 COVID-19 发展态势影响,政府、卫生部门和学校等许多组织都发布了会影响活动安排和日常生活其他方面的紧急通知。通知内容包括关闭设施、调整活动时间以及开设新的医疗设施(例如检测中心)。以下是特别通知的一些示例:
- 居家避疫指令通知
- 设施关闭通知(如学校停课或公共交通停运)
- 政府福利通知(如失业补助,带薪休假或一次性补助)
- 隔离指南
- 旅行限制
- 关于开设新的免下车检测中心的通知
- 关于将活动从线下转为线上举办或取消活动的通知
- 关于修改营业时间和购物限制的通知
- 疾病传播统计信息和地图

如何实现 COVID 19 通知
您可通过以下两种方法实施 COVID-19 通知:
- 在您的网页中添加
SpecialAnnouncement
结构化数据(推荐做法):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。如需实施 COVID-19 通知结构化数据,请按照这些步骤操作。 - 在 Search Console 中提交通知:如果您无权访问网站的 HTML,或者您需要快速提交通知(但是没有时间实施结构化数据),可以在 Search Console 中提交通知。该工具仅适用于设置为在发布后的一个月内失效的短期通知。此外,您目前无法更新通知(借助结构化数据,您可以更新通知并添加更多详情或延长日期)。了解详情。
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。
- 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。
- 遵循指南。
- 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)。
- 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。 - 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。
在 Search Console 中为您的网站提交 COVID-19 通知(Beta 版)
政府机构和官方卫生组织可以在其网站上提交重要的 COVID-19 通知,尤其是在无法使用结构化数据的情况下,此工具尤其有用。通知内容包括关闭设施、调整活动时间以及开设新的医疗设施(例如检测中心)。Google 搜索可以利用这些信息更好地理解您的网页内容,并在网页结果旁边向相关人员显示此类重要通知。
打开 COVID-19 通知提交工具功能可用性
由于 COVID-19 形势的紧迫性,此功能处于积极开发阶段,您可能会发现相关要求或指南有所变化。我们关注的是来自卫生组织和政府机构的通知。您可能无法立即在 Google 搜索中看到相关结果。您可以提前提供结构化数据或在 Search Console 中提交通知,确保在该功能推出时您的通知符合条件。这样有助于 Google 了解 COVID-19 通知背后的数据,我们会根据这些数据扩大范围,为更多用例提供支持。

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:
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:
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。
- 在 Google 搜索中心论坛中发帖提问。
