What is high weight external chain and common high quality external chain misunderstanding

What kind of link is the high weight outer chain? The high weight outer chain must meet two conditions, first is the export link of the high weight page. However, is the export link on a high weight page necessarily a high weight link? The answer is no, what is the second condition? This link is a high weight link only when it has clicks. The more clicks, the higher the weight. (By the way, I also remind my friends who buy the black chain here that even though the page of the link you buy has a high weight, the weight that can be transferred is not very much.). The above two conditions for judging high weight links are introduced, and the following three common high quality external link mistakes are introduced:

　 High quality error zone I: Baidu Knows (error zone index 5)

I believe that many friends who have just come into contact with SEO will listen to others who say that Baidu knows how high the quality of a link is, and some even advocate that a link Baidu knows can top 10 or even 100 High end website construction The forum signed. In fact, it's not true. Let's analyze according to the judgment conditions of high-quality links. How high is the link weight that Baidu knows? First, let's see how high the page weight Baidu knows. As we all know, the higher the weight of a page, the better the ranking, and ranking is the embodiment of a page weight. You can search "Is there a psoriasis hospital in Qingdao", and you can see that Baidu, ranked second, knows that the title is completely matched, while the title on the inside page of 120, ranked first, is not completely matched. From this, it can be judged that Baidu knows that the weight of this page is less than that of the page of 120, So while other conditions remain unchanged, Baidu knows that the weight of the outer chain on this page is not as high as that on the first page. The above is just an example (I've cut a picture for you here, but I hope you'd better search it yourself). There are still many cases, so I won't list them here. Therefore, Baidu knows that the quality of the links left is higher than that of the forum signature, but they are not high quality links.

　 High quality external chain error zone 2: Baidu Post Bar (error zone index 7)

As Baidu knows above, many friends posted on the forum that Baidu Post Bar is Baidu's own product, and leaving a link is definitely of high quality. In fact, it is also a common mistake. The judgment method is the same as above. You can try it yourself, find a post at random, and then copy the key words of the title of this post to Baidu Search for a try. I think some friends will be surprised to see that this post can't be found on the home page or even the first 10 pages. Therefore, I would like to tell you that the quality of the links left by Baidu Post Bar is not high at all, even inferior to the signature links of some high weight forums, such as Beijing website production The company's signature links are no lower in quality than those left in Baidu Post Bar, but they are dozens of times easier than those left in Baidu Post Bar.
