In most cases, you’ll likely be fine keeping your website public and simply monitoring how your URL is distributed. However, if you want to ensure that your wedding (and the details around it) remains a private affair, then it’s a good idea to make your whole website private. You can do this by password-protecting it. Just remember to include the password when sending out the link to your website. Alternatively, you can make some pages of your site public, while keeping others private. For example, you can make it so that certain pages are only visible to your wedding party.
