I have a whole bunch of relevant domains forwarded to a single site. Is there a reason I shouldn't do this...? It's improved my traffic significantly, but I can't tell in what way it has affected (if at all) my search engine positions. I do pretty well with Google; #21 on my most relevant keyword... what's the thinking on multiple domains pointing to a single site? Good? Bad? In what way, and if 'bad', what should I do differently?
Apologies if this sounds vague; I'll give more details if anyone's interested in tossing this subject around.
Thanks!
