Subdomains and Google

What does google think.

[dnbjason]

I have a huge website (10,000 pages) and having problems getting some of my deeper folders (www.mysite.com/folder/folder2) in Google. My main page is a high PR5. These deeper folders have enough information and could/should be there own website, so I'm thinking about subdomains. There will be about 195 subdomains if I do this. They all have there own design, so duplicate content is probably not an issue.

What are the concerns I should be worried about in doing this?

I would be linking to each subdomain througout my main website only on about 10-30 pages will have an actual link to a subdomain. Depending on where the topic is talked about.

Every subdomain will link to my main website homepage, but no subdomain will be linked from my home page.

Do I have to worry about crosslink?

I'm not sure for reply, but I think it won't resolve your crawl problems.
Check whole linking structure in your site to minimize the quantity of jumps from home page for each deep page.
IMO, filename or url doesn't involved with this (same domain.com/dir1/page.html vs dir1.domain.com/page.html)

Google seems to be picking up new domains a lot faster these days. I'm figuring that

folder2.mysite.com/index.html

will do better then

www.mysite.com/folder/folder2/index.html

My topics has a lot of information to be their own website really. The only thing I'm worried about is to many subdomains and crosslinking. As I said before if I do this I would have to add 195 subdomains.

Concerns are the 195 subdomains. Also, using that much canonicals means a lot more work - you should have a reasonable number of external links pointing to the subdomain's sites in order to avoid looking suspecious. In google's eyes, if all links to your new subdomains would come from your own sites (the other 194 subdomains), it would pretty much look like a artificial construction to increase page rank.

Carefull! Sometimes a better site structure, categorized site maps etc. do the job.

Before you do anything wrong, you might want to take a look at the Link Developement Forum [webmasterworld.com] and additionally do some searches on canonicals [google.de].

Probably true - but getting in quick doesn't automatically mean not getting quick out again.

The subdomains will not be linked together, they will just be linked to the main page. Do I still have to worry?
