Super chain: Super Outside the chain is a collection similar to Alexa ranking query, PR query webmaster commonly used to query the site, because these sites are mostly query record display function, and query records can be Baidu, Google, Sogou and other search engines quickly included, so that the formation of the chain. Because this is the normal query generated outside the chain, so this outside the chain of SEO effect is still very obvious. This large number of repetitive work can be given to the machine to operate, and was widely used in large areas.

Above is an explanation of the super outer chain. And for super outside chain each road seoer to this mixed. I am more in favor of, and my friend once wrote an article criticized this practice, think is the outside chain of rubbish, do not have any help.

Here are some of my research on super outside chains:

By oneself to some hot word rank by the front of the research. Found that there is no exception, all have super outside the chain exists, and the number of super chain is not small. Of course, extremely individual use of virtual outside the chain bug Black Hat site except. As shown in figure: Index 14,000 of the key words ranked the first page second station. Use a lot of super outer chain.

Figure: Beauty picture keyword 5w+ index. Ranked first site, the use of a large number of blog sprocket, batch level two domain names, virtual outside the chain, such as black Hat technology is not taken for reference. Just talk about super outside the chain, so choose the fifth site.

There are more examples I will not enumerate. Let's look at the weight ratio of the super chain. Domain home is not the first. This question I believe many stationmaster met, including my present blog. But I'm not in a hurry. Put aside other not to say, look outside the chain weight value analysis alone. See Baidu official Explanation: Domain this label, the higher the link weight, ranking higher before. The understanding of this sentence, we first to analyze Baidu itself. Domain. Figure:

In turn is: "Baidu, you Know"--baidu--Bar-promotion--mp3--know-space ——.....

Analysis: Baidu a bit, you know that the first no doubt. CCTV ads are also playing this do not want to first, the weight of the lever drop. Baidu second is not to say. Stick than promote MP3 know hot affirmation. As for the library, encyclopedia. Library rankings Baidu Front. A willing friend can go and see for himself. Then look at it in turn, is indeed in accordance with the popularity of the law of approval to arrange. The popularity of a certain aspect of recognition also indicates the weight value. Indicates that Baidu's own product weight value of the distinction between the high and low. (PS: After Seoser can be based on Baidu's own product weight value of the corresponding outside the chain) don't worry, domain under Baidu can not prove anything. We are in the domain 163, check whether is according to the weight value high and low rank.

163 mailbox first, no doubt. followed by the knowledge--Library--Know

Above our domain Baidu analysis, know Baidu to own "Baidu know" weight higher than "Baidu Library" weight. So domain 163 so rankings is normal. Of course, it must be related to other elements of the content. Here is a simple analysis, not deep digging. Interested in the basin friends can continue digging deep to verify this analysis.

The above two example combination analysis proved the Baidu official words: Domain This label time, the link weight is higher, the rank is higher before. OK, we continue to analyze the weight of the super outer chain.

Figure I: Continue the above keyword 5w+, ranked 5th station. Super outside chain weight more than cool six video stations.

Figure II: This time, a bit ruthless. Keyword latest movie. Index 10w+. Super outside the chain weight station below Baidu space, potatoes. Second only to the next.

I will not enumerate more cases. Judging from the rankings, super outside the chain accounted for a large proportion of the weight.

Effect: The effect of this thing only people to do to find. After all, I No. It's not a strong explanation.

is k: Anything used properly is good, the use of excessive affirmation by K. Whether it's a blog or a super chain. Degree of certainty. 10,000 outside the chain of which 12,000 super outside the chain is no problem.

Through the above analysis. We've come to. Super outside chain is effective and the weight is not bad, easy to operate, the auxiliary effect is extremely strong. So where is the weakness of the super chain? Many people have criticized this weakness: instability.

Analysis of the reasons for instability:

Because the outer chain is cached for a long time. Baidu included whether to keep pace

3, other seoer mouth reason not to elaborate.

Through my research for a while. Super outside the chain is included in the interval is 5-10 days. Example June 20 included once, then may June 28\29 Day will be included once again. 1-2 times a day to brush the effect is obvious.

So far, the analysis of super outside the chain. The details may not be explained too clearly, logic may have loopholes. Careful analysis, serious thinking, it makes the index 10 tens of thousands of ranked first to second of the station are in use. Is it really rubbish? Do seo, as seoer whatever should try. Can not be too negative things, but should be further study under the judge, this is the spirit of Seoer!
