How to send private link to page w/o being indexed

Hi guys,

We want to start sending private info to clients (in the form of a page). We don't want to password protect or have to have them login anywhere. And we def don't want google (or anyone for that matter) to find it.

Is the best way to use the 'Pubic Post Preview' plugin, send the link to clients, and then be extra safe by disallowing these links in the robots.txt file like explained here?:

I still think google can index drafts so not sure if the plugin is completely safe (can't find any documentation) without editing robots file.

If I'm missing something please let me know. You guys are the experts :slight_smile:

Thanks in advance!
Derek
