good day, and sorry if I have put this in the wrong area
I am in the process of creating a new website for my business, my old site is looking old and bloated, but I have 2 domains platinumcomputers.biz and platinumpc.co.uk, just wondering if anyone has ideas of how best to use these

My suggestion is choosing domain name is depends on your business,product or brands based on,so check with required and suitable domain name for your site.

Hello

I think so your business best domain is .biz

thank you for your reply, can I ask do you have any suggestions for the .co.uk to possibly help the .biz in regards SEO or ranking?
