对外部托管博客使用子域的 SEO 后果？
在 Wordpress 或 Blogger 上使用子域托管博客是否有任何 SEO 缺点？ 我不想麻烦地为我的网站创建博客模块 - 我宁愿只设置一个 CNAME 条目并将子域指向免费的 Wordpress 或 Blogger 帐户。 Google 是否会通过声称我有“重复内容”（即每个博客条目的介绍文本将出现在我的主网站上，并且完整的详细信息将在 Wordpress/Blogger 上可见）来惩罚我这样做？ 将博客功能合并到我的主网站中是否更好？ 使用免费博客主机的这种子域/外部托管方法是否还有其他潜在的缺点？
Is there any SEO disadvantage in using a subdomain to host a blog on Wordpress or Blogger? I don't want to go to the trouble of creating a blog module for my site - I'd rather just set up a CNAME entry and point a subdomain to a free Wordpress or Blogger account. Will Google punish me for doing this by claiming that I have "duplicate content" - i.e. the intro text for each blog entry will be on my main site and the full details will be visible on Wordpress/Blogger? Is it better to incorporate the blog functionality into my main site? Are there any other potential disadvantages to this subdomain/external hosting approach using a free blog host?

自托管博客有很多优点。
There are a lot of advantages to self-hosting your blog.
威廉·奥布斯特（Willem Obst）的回答提出了一些很好的观点，但有两个不正确的严重指控。 我知道这些是不正确的，因为我是 WordPress.com 团队的一员。
Num 1. 如果存在 ToS 问题，我们会与客户合作解决问题。 在极少数情况下，博客被暂停，客户仍会得到协助导出其内容。
Num 6.我们没有带宽限制，而且从来没有。
许多公司使用免费的 WordPress.com 作为他们的博客。 这里有些例子
http://wordpress.org/showcase/flavor/wordpresscom/
WordPress.com 也是是一个博客社区，可让您接触到大量受众以及全局标签页面等社区功能。
这是建立博客的好方法，而且没有锁定。以下是一些朋友在 WordPress.com 上创建的博客示例，后来开始自行托管该博客，以获得威廉姆所描述的额外灵活性：
http://blog.bootuplabs.com/
最后回到原来的问题。 这是一个混合包。
反对使用子域名的人将重点关注谷歌和其他搜索引擎，它们通常将子域名视为拥有自己权限的自己的域名。
专业子域名所有者将重点关注它是在谷歌和搜索引擎中获得结果的另一个机会。 “启动实验室”示例就是如此。 （尽管如此，Google 的 Matt Cutts 一年多前就承诺正在改变。 ）
与 SEO 无关，许多团队出于网络安全原因一起使用子域或单独的域。 您可能会注意到 http://blog.flickr.net/ 位于 flickr.net 而不是 flickr。我理解，主要是出于这个原因。
Willem Obst answer makes some excellent points, but two serious accusations that are not correct. I know these are incorrect because I am part of the WordPress.com team.
Num 1. If there is a ToS issue, we work with our customers to resolve the issue. In the rare case, where a blog is suspended, the customer is still assisted with exporting their content.
Num 6.We have no bandwidth limits and never have.
Many companies use free WordPress.com for their blog. Here are some examples
http://wordpress.org/showcase/flavor/wordpresscom/
WordPress.com is also is a blogging community which gives you access to a large audience and the community features like the global tag pages.
It's a great way to get a blog going, and there is no lock in. Here is an example of a blog by some friends that started on WordPress.com and since moved to host it themselves to gain the additional flexibility Willem describes so well:
http://blog.bootuplabs.com/
Finally to the original question. It's a mixed bag.
The nay sayers to using a subdomain will focus on Google and other search engines generally treating the subdomain as it's own domain with it's own authority.
The pro subdomainers will focus on it being another opportunity for a result in Google and the search engines. As is the case for the "bootup labs" example. (Although, Google's Matt Cutts over a year ago promised this was changing.)
Unrelated to SEO, many teams use a subdomain or separate domain all together for web security reasons. You may notice that http://blog.flickr.net/ is on flickr.net instead of flickr.com primarily -- I understand -- for this reason.
一言不合
实际上是个好主意。 自托管博客往往集成了很多内容，例如自动pinging
No in one word
Actually a good idea. Self hosted blogs tend to have a lot integrated into them e.g autopinging
回答这个问题......不。
你问的问题也有点模棱两可。 您是否想要托管自己的博客，即在您自己的服务器上的子域下运行它，或者您是否想要添加链接到您的博客的 CNAME 条目。
两者都有好处：
运行自己的 - 优点：
运行自己的 - 缺点：
使用第三方博客 - 优点：
使用第三方博客 - 缺点：
关于 SEO 和博客：
如果您使用 CNAME 重定向，您的博客不会受到 GOogle/Yahoo/其他搜索引擎的影响或处罚到另一台主机。
如果内容不完全重复，例如，如果您的主域使用子域上托管的博客内容的标题和摘要，您将不会因重复内容而受到搜索引擎的处罚。
如果您遵守主要的 SEO 原则，那么您的博客就没有理由在子域上受到影响：
希望这有帮助。 如果您有任何其他问题，请随时询问
In answer to the question.... NO.
The question you asked is also a little ambiguous. Are you wanting to host your own blog ie run it on your own server under a subdomain, or are you wanting to add a CNAME entry that links to your blog.
There are benefits to both:
Running your own - Advantages:
Running your own - Disdvantages:
Using a third party blog - Advantages:
Using a third party blog - Disvantages:
In regards to SEO and blogs:
Your blog is not going to suffer or be penalised by GOogle/Yahoo/Other search engines if you use a CNAME redirection to another host.
You will not get penalised by a search engine for duplicate content if the content is not completely duplicated on, for example if your main domain uses the title and summary of what is on your blog hosted on the subdomain.
If you adhere to the main SEO principles there is no reason why your blog would suffer on a subdomain:
Hope this helped. If you have any other questions feel free to ask
