What ordering it asks for

The exact hostname visitors will type. A certificate for example.co.uk does not cover shop.example.co.uk.
A certificate signing request (CSR) from your web server. No CSR yet? We can generate a key pair in your browser — the private key is downloaded to your computer and never sent to us.
A way to prove you control the domain: an approval email to an address at it, a file on your web server, or a DNS record.
