网络认为所谓的“外链为皇”主要讲的就是网站外部链接对seo网站优化的作用，强大的外链建设是网站制作获得高权重和较高排名的基础，但是很多时候也是常常因为外链的问题经常导致k站，降低权重活是百度的十一位现象，俗话说：物极必反。在我们做外链的时候也应该有个度，而很多人都很难把握住这个度。下面我简单讲讲在外链建设方面的一些常见问题和会导致的后果。
luxuries that so-called " china network outside the chain for the emperor " is mainly about site external link on the seo website optimization effect, powerful outside catenary construction is the production site to obtain a high weight and high ranking based, but is also a lot of time often because the outer chain problems often lead to k station, reduce the heavy work is right baidu eleven phenomenon, as the saying goes : ". in the us outside the chain when it should have a degree, and many people are very difficult to grasp the degree. here i simply about the outer chain construction of some of the common problems and consequences.
一、外链主题和自身主体类别严重不符(outside the chain of theme and subject category serious discrepancies)
这个概念很早的时候就被人提及过，但是由于外链建设的复杂性和难操控性，往往人们忽略了这点。其实搜索引擎在抓取网页的时候，就会自动来审核文章所属的类别，也会审核其中外链目标页面所属行业类别，如类别相似，搜索引擎会认为该站是自主的给与目标站投票。所得到的权重也会最大化。当然，作为外链的建设都需要去同行业去做的话，这样的操作性相当的难，那么就需要在新闻类的文章下足功夫。例如将自己的文章发布到admin5或chinaz上，因为搜索引擎对于新闻类和资讯类的文章的外链的抓取，就不在十分强调是否同行业的。
the concept is first has been mentioned, but because the outer chain construction complicated and difficult to control, people often ignore this. in fact, search engines crawl webpage in time, it will automatically to review articles belonging to the category, which will check outside the chain of the target page industry categories, such as similar types, search engine thinks the station is independent to target station polling. the weight will also maximize. of course, as the chain of construction need to with the industry to do so, the operation is quite difficult, so we need in the news articles under foot. for example, his article is posted to the admin5 or chinaz, because search engine to news and information of the outer chain grab, not in the great emphasis on whether the same industry.
二、外链网站涉及非法内容或已被惩罚的网站(outer chain sites involved in illegal content or have been punished website)
这点任何搜索引擎都不太承认，但是经过很多网站的对比和研究，我们发现，搜索引擎的确会因为这样的外链而对所有导出网站进行一个连带惩罚。尤为严重的是涉黄网站所导出的链接，基本无一幸免。(例如之前我群发过论坛回帖，不小心将自己的站发到了涉黄网站，之后的权重就一路降低)所以在做外链的时候千万不可急功近利的去用群发软件，因为你无法清楚你发的外链都发到了哪个站，不要因为一时的简单方便而导致之前所有的努力的前功尽弃。如果要做到一个严谨的seor，那必须做到对自己的外链分析做到100%的掌控。
this is not to admit any search engine, but after a lot of website comparison and research, we find, search engines do so outside the chain of all export sites were a joint punishment. particularly serious is involved in yellow website are basic link, a man. ( e.g. before i send forum replies, carelessly his station to the implications of yellow website, after the weight on the way down) in doing so outside the chain of time must not be eager to use the software, because you cannot know you send outside the chain are sent to the stations, don't because of a convenient and easy to lead to all previous efforts to waste all the previous efforts. if you want to do a strict seor, it must be done on their outer chain analysis to 100% control.
三、大量低质量外链(a large number of low quality chain)
在优化站点的过程中，绝大多数人都会觉得外链越多越好，对于站点的权重和排名也会起到积极的作用，这是一个最基本和最常见的误区。这种做法无论是从网站自身而言还是从搜索引擎的角度来看，都是错误的。因为当今的搜索引擎已经越来越智能，在外链的建设最初搜索引擎的解释就是对方网站给与自己网站的投票，一旦网站的链接过于泛滥，那么就极有可能被搜索引擎判定为链接群发或是一个人的操作。这就违背了搜索引擎对于外链的解释。网络认为一旦搜索引擎对于这样的外链作为群发的判定。所产生的后果是十分严重的，轻则快照延迟，重则直接k站。
in the process of optimizing the site, most people think outside the chain of more is better, for the site weights and rank also will play a positive role, this is one of the most basic and most common mistakes. this approach both from the site itself or from the search engine 's point of view, it is wrong. because many of today's search engines have become more and more intelligent, the outer chain construction initially search engine is the interpretation of website of the other side to give yourself website voting, once the site of a link excesses, then it is highly likely to be sear
