Domain name The biggest SEO problem is that after buying a domain name, the domain name previously obtained by the link is still valid? Are the links weights maintained?

Google has mentioned that many people buy domain names because of the link of domain name accumulation. In this case, once the domain name changed hands, the original link and its weight will be clear zero, no longer valid.

But there are a lot of cases, domain name trading and turnover is not necessarily for links, such as mergers and acquisitions between companies and so on, the domain name changed hands very normal. It is unthinkable that Google acquired the Youtube,youtube domain name to Google, but all the links obtained on YouTube have been zeroed out. In practice, this has not happened.

So how does Google determine if the domain name has changed hands for links or for other reasons? Danny Sullivan wrote a post a few days ago summarizing several situations and communicating the problem with Matt Cutts.

"Some domain names have changed hands, such as mergers and acquisitions, and previous links will be maintained," said Matt Cutts. Sometimes it doesn't make sense to keep links and weights, such as expired or actually expired domain names. Google and all other search engines are doing their best to handle the link problem when the domain name changes hands.

Our system is mainly to detect the sale of expired domain name, or only for the linked domain name trading.

Danny Sullivan lists several things based on Matt Cutts's answer and his observations:

Buy expired Domain name

This situation can basically be sure that the original domain name link and weight will not be retained. In many forums to see the webmaster in the discussion of the so-called fall of the domain name, many people are enthusiastic about the overdue domain name trading. In fact, if it is for these expired domain name before the link or PR, there is no meaning.

Buy the domain name and then turn

Some people find a good domain name to buy down, and then do 301 to their own main site, hope that the accumulation of the domain name link can be transferred to their main website. In this case, I am afraid the original domain name on the link weight can not keep. Because of the turn, Google is able to determine the domain name transfer is to pass the link weight.

Google and other search engines will probably notice changes to the registration information, even if they keep the domain owner information unchanged.

Continue to operate the website after buying the domain name

If the domain name is bought, the original site is still operating, the content of the site has not changed, this situation is usually able to maintain the original link and weight of the domain name.

Because of the change of domain name caused by company mergers

Similar to the above, this domain name should not change the name of the original access to the link and weight.

The question is how accurately Google detects the difference between a takeover of a company's domain name and the transfer of its hands for links.

My recent observation also shows that the purchase of links and weights are relatively strong domain name, change its content want to do new keyword rankings, it also seems difficult, the original domain name in the domain name changed hands after the basic disappeared, and do a new site almost.

The effect of renewal time of domain name

Many SEO think domain name renewal time to the domain name weight also have influence, I also always think so. Logic is very simple, the continuation of the 10-year domain name description of the owner is very serious, very seriously.

On this question, Matt Cutts said: "As I know, no search engine confirms that the domain renewal time is counted into the ranking algorithm." If a company thinks so, it is very troublesome. The main reason for the renewal of domain name should be, this is your domain name, you intend to hold a period of time, and do not want to worry about which day domain name expired.

Matt Cutts answered the questions with caution and tact. Is there any use for renewal? Everyone will have different interpretations.
