A private site is a website that can only be viewed with the permission of the owner or administration.
The internet is a marvellous tool for sharing information but sometimes a degree of discretion is needed. Would you trust Facebook or Google? I don't think so.
If you want to keep it private but accessible to selected people, you need a specialist. That's where I come in.
Perhaps you have something to share on the internet but only want invited people to see.
Perhaps you are offering a private service.
Perhaps you want to sell something but don't want the whole world to know.
Whatever your reasons it's your business and you have the right to keep it private if you wish.
