When I make your site for you, it will have a default name like https://sites.google.com/site/yourname - this domain name is fine and if you wish, you can use this as it is.

Some people like to use a custom domain instead, which might be something like www.yourname.co.uk - this can be a bit easier to remember and pass on to other people but it isn't essential; it's your choice.

If you want a custom domain, you will need to purchase the domain name yourself as this is a recurring yearly cost. I have free instructions I can email you about how to do that. I can then also either email you further instructions on how to set this up to link it to your new site yourself or if you'd prefer, I can do this for you for a charge of £20 (see payment page).
