Gatsby 更新盖茨比博客上的发布日期
我需要一点我的网站的方向。我想在编辑博客时更新其发布日期。日期是slug的一部分，但不是完成URL的一部分。我的网址是wesite.com/blog，这很好。我只是不确定谷歌是否会选择这个日期。我在元数据中没有看到它 但是，当我更改该日期时，它将无法完成构建。它失败了，我必须恢复。另一个选择是不向谷歌提供日期。我想我可以从gatsby配置中删除它，但我不确定如何验证它。我没有在博客页面上显示发布日期，但它在meta中，并显示在SERP中。以前有人碰到过这个吗Gatsby 更新盖茨比博客上的发布日期,gatsby,Gatsby,我需要一点我的网站的方向。我想在编辑博客时更新其发布日期。日期是slug的一部分，但不是完成URL的一部分。我的网址是wesite.com/blog，这很好。我只是不确定谷歌是否会选择这个日期。我在元数据中没有看到它 但是，当我更改该日期时，它将无法完成构建。它失败了，我必须恢复。另一个选择是不向谷歌提供日期。我想我可以从gatsby配置中删除它，但我不确定如何验证它。我没有在博客页面上显示发布日期，但它在meta中，并显示在SERP中。以前有人碰到过这个吗 require("
