问题描述
在我的大部分网站中,我有很多指向我的其他网站和其他外部网站的外部链接.我需要知道什么时候在网站中使用 rel="nofollow"
或 rel="external"
更好?
In most of my web site I have a lot of external links to my other sites and other external sites.
I need to know when is better to use rel="nofollow"
or rel="external"
in a website?
推荐答案
您可以使用 external
用于每个指向不同网站的链接,无论它是否属于您,是否在同一主机上.
You may use external
for every link to a different website, no matter if it’s yours or not, if it’s on the same host or not.
您可以将 nofollow
用于您不使用的每个链接't 背书(例如:搜索引擎不应假定它是相关链接,也不应为此链接提供任何排名信用).
You may use nofollow
for every link that you don’t endorse (for example: search engines shouldn’t assume that it’s a relevant link and should not give any ranking credit to this link).
您可以对同一个链接使用这两个值:
You may use both values for the same link:
<a href="http://example.com/" rel="external nofollow">Foobar</a>
<小时>
请注意,external
并不表示应在新窗口中打开链接.
Note that external
doesn’t convey that the link should be opened in a new window.
请注意,搜索引擎机器人(支持 nofollow
)可能仍然follow一个 nofollow
链接(它不禁止关注它).FWIW,还有 meta
-robots
关键字的 nofollow
值(可能意味着相同……或不同,具体取决于您遵循的定义).
Note that search engine bots (that support nofollow
) might still follow a nofollow
link (it doesn’t forbid to follow it). FWIW, there is also the nofollow
value for the meta
-robots
keyword (which may mean the same … or not, depending on which definition you follow).
