-You recently joined a group or liked a Page that is similar to other Pages or groups you've joined in the past.
-You've clicked on a lot of ads or engaged with a lot of sponsored posts.
-You've been tagged in a lot of photos or posts.
-You've searched for a lot of terms on Facebook.
-You've interacted with a lot of Pages or public figures.

-Click on the down arrow in the top right of your Facebook page and select News Feed Preferences.
-Under Prioritize who to see first, click the stars next to the names of people or Pages you want to see first in your News Feed.
-You can also click Unfollow people to hide their posts to declutter your News Feed.
