By default, Link Whisper only creates linking suggestions for posts that have been published. But you can change what post statuses you want to create links for from the Settings.

In the settings, you can choose to create links for posts in the 5 post statuses WordPress supports natively:

• Published.
• Private.
• Future.
• Pending.
• Draft.

The settings for the post status are at the bottom of the “General Settings” tab near the “Save Settings” button.
