It may appear to be a stupid question but I'm working on the link development for a client. He already has quite a few inbound links but they are spread between 3 urls:- redwidgets.co.uk, red-widgets.co.uk and redwidgets.com. The latter 2 urls point to the 1st one. If the inbound links are to the second two are they useless as far as say Google is concerned because they just point to the main domain?
Should I contact all these site owners and ask them to link to the main url?
Cheers :)
