Zac: domain name Trust

In the last two years, domain name trust ranked Google Algorithm Medium proportion. In many cases, large websites with high trust can occupy a lot of keyword rankings on the inner pages without any effort. Wikipedia is the most powerful domain name trust.

To give domain name trust so much weight, Google is to deal with spam websites. The premise of this logic is that websites that have gained trust are usually clean and have no poor quality content. The spam website is a website with a low level of trust.

This is true, but the side effects are becoming more and more obvious. For example, many people create a content page on a large website with high domain name trust, so they can get a good ranking. This example is common in some highly competitive keywords where black hats gather.

No matter what the advantages and disadvantages are, this is a fact that we can only adapt to the website.

I think the most important factor in domain name trust is the following.

Links from other highly trusted websites

Google's initial explanation of trustrank was to manually select the most trusted seed websites, such as Yahoo, The New York Times, and Wikipedia. Then, based on which other websites these high-quality websites are linked to, find the second-level trusted domain name. That is to say, if your domain name has links from Yahoo, The New York Times, your domain name will gain Level 2 Trust.

Similarly, second-level trusted domain names can bring out a group of third-level domain names, and the third-level domain names are connected to fourth-level domain names. The farther away from the core, the lower the trust level.

This concept is somewhat similar to the prvalue, all of which are marked as links, but it is not a prvalue.

There are only over 100 trusted websites at the core. They are all manually selected, rather than measured by the prvalue. This domain name trust is not calculated by page, but by domain name. Therefore, domain name trust does not depend on the number of links, especially the number of spam links. In the past, I emphasized that quality, not quantity, is the most important thing for links.

Domain Name history

This includes the time when the domain name was first registered and the page was crawled by Google for the first time.

Obviously, the earlier the domain name is registered, the higher the trust level. Very simple and effective. If you have a domain name that has been registered for ten years, it is a powerful weapon. If you have a domain name registered for 15 years, no matter what you use it for, it is likely to be invincible.

My own oldest domain name is only 6 years old. That is why I am not satisfied with the domain name I post on Seo every day, but I do not intend to change it. Even two or three years of history, new domain names cannot be obtained. This is a resource that cannot be repeated.

Whether the website content is original and updated

The selection of more than 100 trusted domain names at the core is done manually. We can imagine that the requirements for content Originality must be a large proportion, and these websites must be updated frequently. Algorithms can be fooled, but they cannot be fooled, especially when it is important.

It is hard to imagine that a collection site will be regarded as a highly trusted website. at least at the beginning of the website, it must be based on originality. After obtaining a certain degree of trust, adding some reposted content may be harmless.

Of course, there are some other details that affect the trust of domain names. I think the most important thing is the above three conditions.
