How does Google treat Sub-Domains?

[Mercenary]

Quick question guys..... Just wondering how google treated the use of sub-domains in terms of page ranking. e.g. if i had a site called www.sex.com then setup a sub-domain of - www.big.sex.com which had the same contents as www.sex.com, then submitted that to google, would it be included? Is there any actual benifits to doing this?

:)Thx

If the content was the same then no it would not be, one would be replaced, most likely the one with less links to it. When using sub-domains name sure it has unique content so you don't get penalized.

welcome to webmasterworld.

afaik, Google treats sub.domains as seperate entities from the main domain.

also there would be NO point duplicating the content of domain.com over to sub.domain.com unless you are looking for a penalty for duplicate content.

(I may be completely wrong here, but I think the above is the correct scenario)

thx for the quick reply........just been reading up on cloaking in these forums....so basically doing what i suggested it considered cloaking and therefore a big 'no no' with google?

Matters how you do it and how well aquainted you are with it. Google doesn't recommend it especially for trying to manipulate data to extremes. However it is done all the time, so if your new at the topic before you do it research and research -- you wouldnt wanna mess up everything you've done thusfar with your site, cloaking can be a very risky area for the unexperienced.

so would the pr be different between the two sites or would it be the same?

A sub-domain is a seperate site and should have its own pagerank.

Exact duplicate content and you're starting to look for trouble.

Intelinking between domain/subdomains seems to be regarded as interlinking within one domain.

Sub-domains rock! I've been thoroughly testing this theory on [snip]. I've been building out sub-domain names for just about every webpage.

The conclusion is sub domain names are very effective at lifting your search engine positioning for niche products, less so for generic (highly competitive) search terms.

Take a Google search for a niche [snip] product like "[snip]", a webpage that is 3 pages deep into our website (with a homepage PR of 6) and we're still in the top 10.[snip - google search]

Even better still, if you are reaching a local market, like us - we're an Australian [snip]company - the results are even better. You can get a whole page of results. Take "[snip]" and of course, [snip]is 1st, but we've got 7 other webpages in the top 10.[snip - google search]

Hope that doesn't make me sound too proud, I'm new to the forum and wanted to make a contribution before I ask my own questions :-)
