How does Google judge the age of a domain?

1. Google puts trust in certain sites based on how old they are. What information do they use?

Age of domain per WHOIS? Or how long that site was first crawled in Google's cache?

2. What if you buy a domain that expired, which was previously owned for many years? Remember, the domain was expired and has a new recent "registered" date on it's WHOIS listing. Will Google view this as a "new site"?

 

I **THINK** using whois to get the age is useless, because each TLD have a different syntax for Creation or registry date.

The easier and obvious way Google should do is to get the first date the domain was indexed..

In this case (domain age), I **think** buying a expired domain would be a good idea..

 

Sometimes they reset domains age and trust when they expire.

 

This is also my understanding. Once it expires - it becomes a brand new domain in essence

 

age is a crucial factor that is so many times over looked.

age is a factor for basically every optimizing factor, link age, domain age, interior page age etc. etc.

the older the better, across the board.

 

Thanks for telling me what I already know Capt Obvious.

 

Thanks, that's what I was worried about.

The guy who runs BlackhateSEO who was interviewed on Shoemoney's show said for his final tip that it's best not to register a new domain, but to buy an already existing one. You'll save a lot of time that way. I was wondering about the specifics of this.

 

Since it seems to be questionable, if one plans to build a quality site, I would say buy an existing one. Thanks.

 

You are right.

I have a lot of domains (not .com, .net or .org) more than 5 years old and there is no way for Google to read their foreign WHOIS (outside the US) registries.

Upon registration, a new birth cert will be issued despite many reincarnations.

 

I'm thinking maybe Google has a special classification for foreign domains.

Maybe foreign domains are ranked low on the US version of Google, but high on their own version of Google (like Google China or something like that).

 

Do they use archive . org ?

 

I don't see why they would when their OWN archives (cached pages) are far more detailed than Archive.org's.

I can promise you they don't use Archive.org, lol.

 

This is also my fear, recently I have purchased a .com domain which about 1 and a half year a go was in use and it was ranked pretty high, (which I don’t know why they let it expire, I think maybe they where band from the SE’s, I don’t know) however I do hope that this is not the case. P.S I am still not even indexed

 

Did I quote you and respond to you. No.

I was informing others who might not have been up to speed like you supposedly are.

Why dont you email google and ask them. You will probably get a better response then posting on a forum and bashing people who responded.

 

But it wouldn't be as fun, now would it?
