New forum sub-domain SEO strategy?

[len backus]

I operate a forum with a 7 year old domain name and I am about to start 2 more forum sites as off-shoots of this one and with their own, new domain names. Is there any way to set up the new ones as "sub-domains"of the 7 year old one in a way that they would get the same search engine juice that older domains get because of their age?

your technique is logically good, but you do not need sub-domains...

a main link to your new sites inside the header of the old site is enough... google will crawl the new links anyway, so it will visit the new sites...

That is great news, thanks. So you are saying I would set up a totally new domain, and then simply put that landing page URL into the header of the 7 year old site. Can you be more specific about just how to do that please.

Can you think of any sites that you know are using this strategy now?

it's a well known strategy called "LinkBack" or "TrackBack" depending on the system you're on...

Google is happy to have linkbacks on a site, it help indexing other sites without having to search for content or references...
