General Search Engine Marketing Issues Forum

We are corporately working to get as much branding and the SEO value to the domain "domain.com" as possible and wanted to open a discussion about the pro/cons of the following:


We are trying to get an understanding of the impact to SEO if we begin running some web forms under a URL of "resources.domain.com/ibm" for 2-3 months and then change the location to be www.domain.com/resources/ibm and do redirect of the original URL "resources.domain.com/ibm".

Also, how are 3rd level domain ( i.e. resource.domain.com ) compared to primary domain ( i.e. domain.com ) as a base URL for web sites for SEO rankings?
What the best practice for getting them to be advantageous to each other?

Thanks in advance,
