The role of the site's external chain to SEO

I believe that a lot of SEO experts and sunshine like, have had the same experience, that is, do not understand how SEO is what a magical thing, in the end how can make some specific keyword rankings up?

Oh, it is very strange, I was very difficult to understand ...

In addition to the good internal structure and the chain outside, the chain makes very important elements, the important index is: ★★★★★, five-star important, quack ....

Let's make an analogy:

Small A and little B are the students of the same class, small a good results, but do not love to talk, not many friends (outside the chain is not much), the results of small b can also, as small a, but smart and lively, a lot of friends (outside the chain), which also and many teachers have a good relationship

I (search engine) when chatting with the teacher, the teacher said that the small B (the chance of a small a will be very small), said his grades are good, so I remember. When my friend asked me about the class (search in search engines), because I knew that little B was more, I would certainly recommend it to him, so that little B had a good ranking ....

See, the outer chain is so important, in particular, the high weight of the outside chain, as I get a little B from the principal's message more convincing me, the weight of the site in the search engine links more authoritative, of course, will let spiders have a greater interest in visiting your website ...

But there will be an unavoidable drawback, is small a good results, even better than small B, but very few people know that the quality of the site in this case is easy to ignore, so with the search engine algorithm, the role of the chain will be gradually reduced.
