外鏈，是SEO網站優化中比較重要的組成部分，雖然去年開始綠蘿算法等搜索引擎算法的重制定對于外鏈的影響使得SEOer一度質疑外鏈的重要性。但是，筆者認為無論什么時候好的外鏈永遠可以給網站帶來驚喜。
The chain, is an important part of SEO website optimization, although last year green algorithm search algorithm developed for heavy chain that SEOer once questioned the importance of the chain. However, I believe that no matter what outside the chain of good will can bring to a website.
之前我們也曾分析過怎樣做外鏈，什么樣的外鏈才能偶成為有效鏈接。那時候我們就突出一個重點高質量鏈接，而制作鏈接的平臺也集中在高權重網站平臺。然而，經過了半年的數據觀察顯示，高質量網站的鏈接并非都能夠給網站帶來“收益”，而我們也誤解了搜索引擎對于外鏈的判斷標準。
Before we have analyzed how to do outside the chain, the chain can even what kind of become effective link. Then we highlight a key quality links, and making links platform also focused on high weight website platform. However, after six months of observation data display, high quality links are not can bring to a website "income", and we have misunderstood the search engine for the judgment standard of the chain.

一直以來，我們對于外鏈的有效性集中在網站平臺的權重、行業的性關系、關鍵詞超鏈接的制作和內容上。而實際上，其中能夠真的為我們帶來有效鏈接的卻僅僅是內容的質量高低，或者說內容能否滿足用戶需求。
All the time, making and content we for weight, effective industry chain concentrated in the website platform sexual relationship, keyword hyperlinks. In fact, one can really bring us a valid link was the quality of content, or content can meet the needs of users.

高權重網站的投票鏈接固然能夠給網站加分，但是我們試想一下，一旦用戶通過外鏈推薦打開了網站頁面，而里面的內容完全不能夠解決用戶的問題，想必他們會迅速離開網頁。那么，用被用來綜合考慮網站制作質量的數據：頁面停留時間、跳出率、PV……可想而知是怎樣的一種數據展示，反而不能夠提升網站排名。
The high weight website links as votes is to website points, but we imagine, once the user through the chain recommend open web page, and the inside of the content not to solve the problem of the user, presumably they would leave quickly Webpage. Then, used to considering the production site quality data: page retention time, jump out rate, PV...... One can imagine what kind of data display, but can not improve website ranking.

其實，我們之前將外鏈規則想的過于復雜化，搜索引擎對于外鏈的考評要求很簡單—滿足用戶體驗，或者說你制作的推薦外鏈是不是用戶需要推薦內容。如果是，那么可以了，不論你的文本鏈接還是非關鍵詞的超鏈接都會被記錄到網站有效鏈接內。反之則抱歉，鏈接不能夠達到用戶要求，你的推薦就會被扣分，外鏈就很有可能被搜索引擎評定為垃圾鏈接。這也就是為什么很多網站明明外鏈很多，但是排名、流量都很低的原因，也是各大搜索引擎一直強調不要制作垃圾鏈接的原因所在。
In fact, we will be the chain rule thought is too complicated, the search engine for the chain evaluation is very simple - to meet the user experience, or you make the recommendation of the chain Is it right? Users need to recommend content. If it is, then, no matter your text link or non key links will be recorded into the website link. Otherwise, sorry, the link is not to meet the user requirements, recommend you will be penalized, the chain is likely to be search engine rated as junk links. This is why many sites clearly outside the chain of many, but the ranking, flow is very low, is also a major search engine has emphasized why don't make spam links.

那么如何來建設被搜索引擎認可的有效外鏈呢？
So how to build effective outside the chain was the search engine?

如同上述，我制作的外鏈要滿足用戶需求，亦或是建立在用戶需求上的鏈接，即便是在短期沒有被搜索引擎所記錄它亦有可能成為有效鏈接。而不能滿足用戶需求的外鏈，即便當下能夠被收錄，也會在搜索引擎數據更新時而被淘汰出局。外鏈的制作我們要以內容為主，打造高質量的頁面，為留住用戶奠定基礎。內容的更新上要符合行業要求，但是更要滿足用戶要求。你可以從搜索引擎下來框或者尾部相關推薦中確定當下用戶需求，然后融合到站內信息中。
As such, the chain I production to meet the needs of users, or is based on user demand on the link, even in the short term is not search engine recorded it also has the potential to become an effective link. And can not meet the needs of users of the chain, even if the moment can be included, but also in search engine data update and be eliminated. The production chain for us to be content, to make the high quality of the page, to lay the foundation for retaining customers. The content of the update to meet the requirements of the industry, but also to meet the user requirements. You can now determine user needs box or tail related recommendation down from the search engine, and then into the station information.

站外鏈接發布制作時候，可以是純文本鏈接也可以是超鏈接，當然在平臺允許的情況下還是以超鏈接為最佳。而發布內容，盡量要晚于站內信息發布時間，可以截取文章的一部分作為發布內容，這樣即可以保障站內信息的稀缺性也可以吸引讀者點擊鏈接繼續閱讀。這里尚品中國重點強調一下，不論的站內信息還是站外內容一定要名副其實，杜絕標題黨，用戶和搜索引擎都討厭掛羊頭賣狗肉的“奸商”。
Outside the station links when, can be pure text links can also be a hyperlink, certainly in the platform allows the circumstances or hyperlinks to the best. And publication, as far as possible to later than the site information release time, can be part of the interception of the content such as scarcity, which can guarantee the station information also can attract readers to click on links to read. Here the author Dennis highlight, irrespective of the site information or outside the station content must be worthy of the name, put an end to the title of the party, the user and search engine hate cheat "profiteers".
