Renew Domain name in long periods

As we can see many websites had renew the domain name for long periods rather than just 1 year. The reason could be cheaper on domain renew and registration, but the most important issue is the traffic, SEO statistic and so on for your own domain name.

I had seen many comments around the SEO sphere, Google and other search engines were monitoring the expiration date of domains in order to evaluate the legitimacy of the websites.

I read the news from the newsletter as below.

For example, domains can be renewed up to a period of 10 years. Valuable
(legitimate) domains are often paid for several years in advance, while doorway
(illegitimate) domains rarely are used for more than a year.

Therefore, the date when a domain expires in the future can be used as a
factor in predicting the legitimacy of a domain and, thus, the documents
associated therewith.

That alone should make people think twice about renewing important
domains for just 1 year. If you then consider that you will probably keep these
domains for many years anyway, and that a longer renewal will also keep away the
risk of losing your domains upon the expiration date, well, you realize that you
probably should do it.

As with most SEO aspects, no one has a definite answer regarding how
Google is treating the matter. Other than an upfront money payment, however,
renewing your domain for longer periods does not have any negative sides, while
it might have positive ones, it is worth!
