rel=canonical 链接是否会删除页面中的所有 SEO 价值？
故事是这样的：我有一个本地公司的网站，该网站将优质内容发布到现场博客。我们正在扩展到一个新的地理区域，我正在构建另一个针对新区域的网站。
我想在新网站上添加一个博客，该博客将从我们现有的博客中提取任何内容/帖子。我这样做主要是为了增加 SEO 的好处，即在您的网站上提供经常更新的新鲜、相关的内容。但是，我当然需要添加一个 rel=canonical 链接回原始博客，以确保我不会因为在两个不同的域中发布相同的内容而受到任何重复内容的处罚。
我的问题是添加 rel=canonical 链接是否会消除发布到新网站的内容的 SEO 价值？
我并不是真的在谈论哪篇博客文章会出现在 SERP 中，因为我知道 rel=canonical 标签的目的是提供内容主要来源的归属。我更关心的是，在内容上使用 rel=canonical 是否会消除网站上相关的、经常更新的内容所带来的次要 SEO 好处，因为 Google 基本上对重复内容“视而不见”。
Here'y the story: I have a website for a local company that publishes quality content to an on-site blog. We're expanding to a new geographic region, and I'm in the process of building another website targeting the new region.
I'd like to include a blog on the new website, which will pull in any content/posts from our existing blog. I primarily want to do this for the added SEO benefit of having fresh, relevant content that's frequently updated on your website. However, I would of course need to add a rel=canonical link back to the original blog in order to ensure I don't get any duplicate content penalties from posting the same content across two separate domains.
My question is whether adding that rel=canonical link will eliminate the SEO value of that content being posted to the new website?
I'm not really talking about which blog post would show up in SERPs, as I understand that the point of the rel=canonical tag is to provide attribution to the primary source of the content. I'm more concerned about whether using a rel=canonical on the content would eliminate the secondary SEO benefit of having relevant, frequently updated content on your website, due to Google being essentially "blind" to the duplicate content.

在大多数情况下，您的问题的答案是“是”。关于 Google - GoogleAnswers (见最后一个问题）。
其他搜索引擎无法维护此属性。
问候。
In most cases the answer on your question is "yes". With regard to Google - GoogleAnswers (see the last question).
Other search engines can not maintain this attribute.

如果您从其他地方提取内容来发布，那么它就不是“新鲜的”。新鲜的内容是新写的。无论您是否使用 rel=canonical，您都不会因为新鲜内容而获得任何荣誉
If you pull content from somewhere else to post, it isn't "fresh". Fresh content is newly written. You won't get any credit for fresh content whether or not you use rel=canonical
规范标记的行为方式与 301 重定向类似。也就是说，具有规范标签的页面的排名大部分会转移到它指向的页面。
The canonical tag behaves in a similar way to a 301 redirect. That is, ranking that the page with the canonical tag has will mostly get transferred to the page it points it.
