Country tld's. parked domains and redirects


Well-known member
I have a .com domain plus say for example 10 different tld's each one representing a country i.e.: (main site)
PLUS a couple of others like
etc etc etc

I was wondering what others thoughts are on the best way to set all these up?

If I park the domains in the .com cPanel and create redirects to the .com then the .htaccess contains 10 or more redirect entries:
RewriteCond %{HTTP_HOST} ^beautytherapistnetwork\.com\.au$ [OR]
RewriteCond %{HTTP_HOST} ^www\.beautytherapistnetwork\.com\.au$
RewriteRule ^/?$ "http\:\/\/www\.beautytherapistnetwork\.com" [R=301,L]
(times 10)
all slowing down the initial landing time for users.

Is there a better way of doing it that will enhance the SEO especially bringing up the user's specific tld in say Google search, best impact for rankings etc etc etc
