I have an established website running under a domain name keyword.com (for the purpose of this example)
Some time ago I also purchased the domains keyword.co.uk, relatedkeyword.net/.biz/.org but I have kept them parked.
How best could I utilise these parked domains to promote the original/established site?
Should I try to build up each of these domains as separate websites and link to the main one? Or should I just redirect/forward visitors straight to the established site?
Basically I just think that their potential is being wasted by just keeping them parked.
Thank you for any advice.
