What is Engagement Bait?
Posts that beg for interaction, like 'Tag a friend', 'Like if you agree' or 'Vote in the comments', exist because algorithms promote whatever gets reactions. Your tap is free fuel for someone else's reach.
Where it comes from
Facebook feed-ranking era (2014-2017)
How it hooks you
Exploits social reflexes: tiny prompted actions feel harmless while they train the feed to serve you more bait.
What the research shows
The tactic worked so well that Facebook itself started demoting 'tag a friend' and 'like if' posts in 2017 after they flooded the feed.

How to resist it
Treat any post that tells you how to react as an ad for itself. Engage with content, never with instructions.
