More than a year later, Google did not start to provide domain name registration services. And Google has said that they become domain registrars, not to provide users with domain name registration services, but to improve the quality of search rankings.

Clearly, if the domain name registration information has not yet become one of the Google ranking factors, at least Google has plans to do so. Most people think that Google has actually considered the domain name registration information in the rankings.

Many people think that as a top-pole domain registrar, Google can get information that our ordinary users do not get. In fact, this is a misunderstanding. The domain registration information that Google can obtain is the same as the information we get from the WHOIS search. Google does not have access to the real information of other domain registrar clients.

For example, many people register domain names with fake name fake addresses. What we see in the WHOIS search is probably a fake name. What Google can get is just this fake name. Only the provider that provides the registration service for this domain name knows the customer's real name, email address, credit card number, etc.

Of course, Google become a domain registrar, there must be his reasons. That is, Google can use API interface to obtain and process the domain name registration information massively. All the procedures to deal with Google, of course, it is not possible to manually check the domain name registration information. With the API interface, Google can quickly create a large number of domain name registration information database. Although this information can be found by ordinary users.

I believe Google has built up a huge database of domain names. They will record the tracking and analysis of the information is likely to include the name of the owner of the domain name, e-mail address, address, domain name validity period, the latest change in Domain name date, domain name owners have changed, when changed and so on.

So what does this information mean for search engine rankings? Give a few possible effects.

For example, the longer the domain name validity period, search engine may give the domain name the higher the trust. Generally speaking, the domain name of a big company is registered for ten years. They can not afford to save a few dollars a year, and the consequences of forgetting to renew the fee. And a lot of Black hat seo is the opposite, generally only registered for one year. Make some money, and when their domain name is sealed, it will no longer be used.

For example, many people want to overcome the sandbox effect by buying old domain names. But it is likely that if the domain name, address, and email change when the field is nearing expiration, Google will realize that the domain name has changed hands. Then the trust of the previous domain name, external links, PR and so on will return to zero.

So many people suggest that if you buy an old domain name, do not immediately get rid of all domain registration information. To a change, slowly change.

For example, there are many people who want to protect privacy, and the use of some domain name registrars to provide anonymous registration services, that is, the real name of the owner can not find the name. While this protects privacy, it can also be risky. Google may reduce the degree of trust in such domains, especially when multiple domain names have similar doubts.

For example, many of the same industry domain names are used by the same domain name registrar, the server is the same or from the same virtual host company, these domain names are also a large number of mutual links and so on. The combination of these phenomena is enough to make the search engine's rankings of these sites adjusted.
