Everyone who does SEO knows that there is a saying in the SEO industry that "content is king, and external links are emperor". So how do we judge the quality of external links? What are the four factors that affect the quality of external links? Below, Chongqing SEO and CQ seoer will talk about four factors to check the quality of the external chain.

Chongqing SEO and CQ seoer summarized four factors, namely, the relevance, authority, universality and health of the external chain.

First, the relevance of the outer chain

I think everyone understands the relevance of the external links of the website, especially the friendly links, which are particularly prominent. Many webmasters will choose to exchange links with their peers in link exchange. We can give an example to illustrate this point. For example, we should choose the best doctor. If you choose by voting (the outer link is equivalent to voting on the website, I think many people know), if you are a doctor, a nurse or a patient, it is definitely more important than a non-medical person or a person who has never seen a doctor. This is the relevance of the outer chain.

Second, the authority of the chain.

The authority of the website outside the chain, this, we went on to say, choose the best doctor mentioned above, when voting, in the medical industry, it is divided into chief physician, deputy chief physician, doctor, nurse and so on. We can clearly imagine that the vote cast by the chief physician must be much more important than that cast by the nurse. Let's stop here. Imagine again that if there is a mayor who doesn't know the medical industry and hasn't seen doctors very much, if he votes for doctors, his vote may be much more important than that of most people in the medical industry. This is the authority of the chain.

Third, the extensiveness of the external chain

The extensiveness of website external links means that the IP sources of external links should be widely distributed. Through the introduction of the above two points, can you think of why the external chain should be widely distributed? Then it says everyone has the right to vote. Like the Internet, every page can be linked. There are four people in a family, and all four people vote for that doctor, which is four votes. Four families, one person in each family will vote for this doctor, so it is also four votes. The same four votes, obviously, the last four votes are much more important than the first four votes. This is the extensiveness of the outer chain.

Fourth, healthy external chain.

Everyone should also understand the health of the outside chain of the website. The healthier the chain, the better. Just like voting, if a criminal or a liar votes for that doctor, I don't think you will admit that vote or believe that vote. It may be counterproductive. Liars say doctors are good. Dare you see a doctor? Of course, you don't have to worry that your website will be spam by competitors. Search engines should judge regardless of weight, but this vote is useless. Because only SB will believe cheaters, and search engines are not SB, as we all know. Of course, if competitors pull thousands of scammers to say hello ... this may be serious. You can imagine. This is the health of the chain.
