Why, you may ask, would you want to keep your website private.
Well one reason is when you are making your site or putting content on for the first time. You are trying new things, writing and maybe then changing page and posts, uploading and downloading photos. You do not want search engines picking up all your mistakes and showing the world. Even thought you may not have told search engines of your sites existence, they might still find you.
All you have to do, is go to settings then reading At the end of the page you will see the following.
Just click on the box where it says, Discourage search engines from indexing this site.
There is no guarantee that they will stop indexing, but they have never on my client sites when I clicked it.
Remember thought, to on click it when the site is ready to go live.
