What is the best way to organize my website.

I am going to be setting up a big website with alot of different blogs, and sites.
My questions is this.
What is the best way for good internal linking strategies and on and off page seo.
Like for example if one of the sites was going to be about mortage loans.
which way would be better ?
1.) mortageloans.domainname.com or
2.)domainname.com/mortageloans

If you could give me some info that would be great thank you.

 

Definitely setup a flow chart (web tree) to help you get organized. If you are creating multiple sites then you should have multiple www.yourdomainname.com . If they are all related then just do www.yourdomainname.com/subpagename

 

Second option is always preferred so go for it. But always make proper chart before doing.

 

your second option is best. Google treats sub domains as New domains. So you get the sandbox effect on them.

 

search google for 'wire frame examples' ... I would post a link, but I'm a Peon.
