Do Subdomains of PR6 sites get sandboxed?

I am looking for advice on domains and subdomains in relation to google

I am looking for advice on subdomains in relation to google. I have a PR6 site that is relatively popular. I have created a subtopic related to the topic of the site and want to create a subdomain for it. Will the subdomain get sandboxed and if so is it for a shorter amount of time? Also...would it be smart to point a new domain towards the subdomain?

Thank you.

Any advice guys? Also, what about a directory structure instead of a subdomain structure ... will google sandbox this. Also, I noticed recently that new content pages that I have been adding have been getting great top rankings in google search results and then after about 4 days disappear. I didn't realize that google is sandboxing established sites' pages. Are they doing this now?

Subdomains can work well, some large sites are creating dozens of subdomains, but you know, the G algo is a black box.

Maybe disappear because SERPs isn't improved with your pages at top (can be measured if users keep looking anothers pages).

Thank you for your response.

It is interesting to see the sandbox effect happen to new pages on an established site because it is VERY much like the effect that happens to new websites. What you say makes sense...however if you copy the title of the new page (the exact words) and you paste it into google .... the page of my site doesn't show up. That to me looks just like the sandbox effect. Very strange. However, if you type the url of the page into google...my new page will still show up in google...this is exactly what happens when a new site is sandboxed.

Has anyone else noticed this effect recently?

From what I've seen/done....

Subdomains do get sandboxed. Google considers them a whole new site and ranks them as such.

But using themed subdomains, and linking it all together properly can be highly beneficial.
As an example; Take a look at about.com, they use subdomains fairly extensively and it works well for them :)

But, as nsqlg, the Google algo is a black box. So this is all only my opinion from what i've seen and experienced.

Cheers,

Thinking... can be the classic dupe filter that day by day is hitting more hard. The pages added at subdomain are content moved from your main domain?

Hi there. Too bad I can't copy the url in for you but I will get in trouble. Actually I did just start a new subdomain on the site but the pages that I was referring to in my post are on the main domain and not in the subdomain. They are just directly in the main folder. The first few days they did wonderfully and I received a lot of traffic - however, they disappeared completely after about 4 days. This has happened before and the pages come back in about a month. My site is 8 years old and has top listings on google for almost all of our pages...it is just new pages that seem to be having problems.

Oh sorry about that - I didn't answer your question. These aren't duplicated files...these are completely new files with no duplicate content. They are optimized just as I have optimized the rest of my pages.
