Benefits about registering/renewing a domain for more than one year.
- SEO scores better: If search engines see that the domain still has a long life until the next expiration date, you get better rankings on your web page assigned to that domain.
- You save money: By registering or renewing domains for several years, you can save money in two ways:
- The price per year when paying several years is usually cheaper.
- The domain providers are used to increase their prices over the years. If you register/renew many years now, you're safe that what you pay now it's cheaper that what you will pay in the future.
- Peace of mind: You know that your domain will not expire soon, so can be assured to keep it and don't lose it.
In any case, when you're going to register a domain, look if there is an offer, because the offer usually is for 1 year registrations. In this case you can register your domain for one year and then immediately extend more years, so you save twice: for the offer and for the bulk discount.
