How to improve the ranking of keywords outside the chain

The nature of the outer chain

Let's look at the nature of the chain, the chain itself is a hyperlink. A hyperlink is a Web page that links to another page that allows users to access a page from one page to another. and search engine, the outside chain is as a weight transmission of existence, a page to do a chain, that is, the external chain is the weight of the page recognition, so it added points. Added to the page, you can improve the weight of the site, thus improving the keyword in the search engine rankings.

Abused outside the chain

Perhaps the role of the chain is too large, perhaps the release of the chain is too simple. Before doing a website, as long as you have good enough outside the chain of resources, in the site is not too bad situation, the basic can do a number ranked, SEO work has become a lot of time to do outside the chain. And in particular, the emergence of the chain of mass tools, but also to allow the spread of garbage outside the chain. To Baidu had to solve the problem, before a large number of http://www.aliyun.com/zixun/aggregation/8980.html "> site was K, a large component is also because of the chain, purchase outside the chain caused by the results." At present, Baidu's approach is to reduce or even ignore the weight of the low platform outside the chain.

External chain factors

Outside the chain is a search engine scoring index, it is impossible to remove. But the original chain as a score is the user for the spread of the chain is the site's affirmation, so the search engine that this is a good site. But now the outside chain to gradually become the webmaster initiative to spread. So the search engine may add a numeric value, which is the number of points in the link. A really good site, not only from the spread of users, but also to this spread can get how many people's recognition. So a bit of the outside chain is excellent outside the chain.

The outside chain as a channel of network promotion

Simply for the weight of the outside chain cost has gradually increased. All day to an IT forum hair a women's web site outside the chain, to Baidu paste a mess to write a lot of things and then take a link with irrelevant, this meaning how much? Like Baidu last time to deal with low-quality content, your site of these destabilizing factors, may also make your site in a moment of collapse. But the search engine is impossible to prohibit the website promotion, that search engine is how to determine whether the chain is junk or promotion, which is related to the relevant, you go to which website what content is consistent, this is why has been said that friendship links need relevance, the chain also needs relevance. Of course, in addition to relevance, some well-known news site reports, but also can give you the weight of the site. But if you look carefully, you will find that both high-quality news sites and related sites, their essence can not be separated from the impact of users directly into your outside the chain.
