This article explains how to hide some of your "likes" from your Facebook diary and prevent them from appearing in the "News" section of your friends. This method only works with the pages you like and the "likes" you give to your own publications.
Steps
Step 1. Open Facebook.com
If login does not happen automatically, log in to open your account. You will need to enter your email or phone number and password
Step 2. Go to your profile page
You can do this by clicking on your name in the navigation menu located on the left side of the home page. At the top of the navigation menu on the left side of the screen you will see your name and a thumbnail of your profile picture.
Step 3. Click on Activity Log
This button is located in the lower right corner of your cover image.
Step 4. Look for the "Like" you want to hide in the activity log
The list is in reverse chronological order, so your most recent likes are at the top of the list.
Step 5. Click the "Edit" button to the right of the item you like
The icon for this key is represented by a pencil and is located on the right side of the screen. Clicking on it will open a small pop-up menu.
Step 6. Select Not visible on diary from the menu
The activity will then be hidden from the diary and consequently will not appear in the "News" section of your friends.
