Thanks in advance for any replies you can give...
We have a directory site which has about 240,000 business profile pages.
The urls for these pages are long and unweildy.
A) e.g. www.site.com/profile(the-company-name)_1234.htm
We want to give each company its own subdomain to make it easier for them to remember and give out to others, put on their business cards etc
B) SubDomain Format : www.thecompanyname.site.com
We are worried about damaging the natural rankings of the main site, or be seen to be cloaking or otherwise trying to spam SERPS - which we are not.
1. 301 Redirect each new subdomain(B) that we create to its currently indexed url (e.g. A above).
2. Make The (B) subdomain website have a frame which pulls in the content from (A). Duplicate Content ?
3. 302 Redirect ?.
Thanks for your time.
