Subdomains -- The Truth

So, I hear very often "Google see's a subdomain as a new domain" is this really true and if so, isn't that a good thing?

Does this mean that links from:

Cocain.Coca-Cola.com ----to----> Weed.Coca-Cola.com

would boost your PR more then links from

Coca-Cola.com/Cocain ----to----> Coca-Cola.com/Weed


So what is that downside of this, what so bad about using a subdomain, you don't need to buy a new domain.


Also, why not put you sitemap at sitemap.Coca-Cola.com instead of Coca-Cola.com/sitemap

is there something I am missing here, or is using subdomains always a win-win situation, also if anything I stated above was wrong correct me because that's my current knowledge on the matter.

Thanks,

John

 

I love subdomains, it has saved me a lot of money. Instead of buying domains and breaking your head thinking about a name that isn't already registered, just buy a generic name and put up as many subdomains as you want.

 

And it truely does act as it's own domain? Nothing is different? 100% like a new fresh out of box domain?

 

Question still stands... Is it like a brand new domain in every aspect?

 

Not quite, Google reportedly use WHOIS data, the WHOIS data will be the same for all sub-domains, so any filters applied based on that data would be equal. In my opinion.

 

So like if your banned or something... Ok, well lets hope that doesn't happen

Thanks for the reply!

 

WOW! imagine one bad subdomain taking them all out.

"never put all your eggs in one basket"

 

But what about if you have a messy site (guilty!) and want to organise it better by taking a big chunk out and channelling it into a subdomain. I don´t know what to do here, because if I go with the subdomain and Google treats it as a whole new domain then I´m cannabalising my own site and cutting page saturation in half, right?

The other reason I want to create the subdomain is because I want to give access to that part of the site only to a supplier. So, to SD or not to SD, that is the question?

 

I would stay away from using a SD if you can. You are right it will cut down on page saturation and some search engines give some extra credit to larger sites.

 

There are some good reasons for using subdomains. See Folders vs. Subdomains.
