Hi, i have number of domains and for them i often have related domains, mostly different tld, but also with ones with hyphens in the name.

I have my own server running ISPconfig3.

The recommend domain alias method is to set up doman alais then create dns settings for this.

The redirect type is set to 'No Redirect' and 'auto-subdomain'

There is also a setting for 'SEO Redirect' !

My question is, how best to use the SEO Redirect setting?

Not looking for anything fancy as it just for marketing purpose, for example one site is my photography site with .co.uk but now have the .photography domain and want to use this on Google+ as web site address.
