I've several domains registered, each a small variant of one another.
fastcar.com fast-vehicle.com fastcar.co.united kingdom fast-vehicle.co.united kingdom
I shouldn't be punished for duplicate content or spammy links by the major search engines like google.
Must I park all of them on the primary domain If only to advertise, 301 redirect these to the primary domain or otherwise rely on them whatsoever?
If 301 redirects are the most useful option, would getting two website hosting accounts be superior than a single?
Hosting account 1 has fastcar.com linked with the dns.
Hosting account 2 has fast-vehicle.com, fastcar.co.united kingdom, fast-vehicle.co.united kingdom linked through dns, and 301 redirects pointing to fastcar.com
