发布外链想必是大家最熟悉不过的了，而且可能也是在网站优化中最为简单的一个步骤了。但是这里有一个很严重的问题是，你的外链是健康的吗，能够给网站带来真正的价值吗？很多人为了做某个关键词的排名，短时间里喜欢在各大论坛、博客添加需要的描文本。而这里需要注意的是，随着搜索引擎的不断调整，论坛博客的外链能够带来的权重已经低的不能再低了，而且很有可能这些外链只是为了搜索引擎而不是真正为了用户，就譬如说我们大家都喜欢去的SEO论坛等等。试想一下，你在SEO网站里发布你的机械或是美容外链，内容不相关的情况下这样的外链到底有多少价值呢？这里的建议是，发布外链的时候要自然而然，千万不要为了追求数量从而让网站的外链太过于泛滥，不过可以多发布一些与本行业相关的网站外链。否则被搜索引擎K站的几率就会越来越大，即使能躲过一次但是谁也不能保证能躲过下一次，所以为了网站的健康，请慎重你的外链建设。
Publishing the Outer Chain must be the most familiar and probably the simplest step in site optimization. But there's a serious question here, is your external chain healthy, can it bring real value to the site? Many people in order to do a keyword ranking, in a short period of time like to add the necessary descriptive text in major forums, blogs. And here we need to pay attention to, as the search engine continues to adjust, the weight of the Forum blog outside the chain can no longer be low, and it is very likely that these outside chains are only for search engines and not really for users, such as all of us like to go to the SEO forum and so on. Imagine if you posted your mechanical or cosmetic chain on an SEO website, and the content was irrelevant. How valuable was that chain? The suggestion here is to publish the outside chain naturally, do not in order to pursue the number of sites so that the outside chain too flood, but you can publish more related to the industry site outside the chain. Otherwise the search engine K station will be more and more likely, even if you can avoid one time but no one can guarantee to avoid the next time, so for the health of the site, please be careful about your external chain construction.
