Domain registration length does seem to be a small factor when Google is trying to make up it’s mind where to rank your site in search results.
I’ve spent time reading snips of blogs, watching YouTube videos, and the only thing I can really determine is your might as well register the domain for 5 years and use a public registration. When you register a domain for a single year you generally renew the thing anyway.
It makes sense to me that Google might trust a domain a small bit more if it’s on a 5 year registration. Typically spammers will register a domain and burn it out (get blocked by blacklists, etc) within a few months, of course they use 1 year registrations…maybe not for long.
Contact me or drop a comment below if you have some hard facts on this, or can point me in a clearer direction.
