Why Facebook Comments Are the Most Powerful Engagement Signal
In 2018, Facebook CEO Mark Zuckerberg announced a major algorithm shift: the News Feed would prioritize "meaningful social interactions" — specifically, comments and conversations. Since then, comments have been the single most important metric for organic reach on Facebook.
A post with 50 comments will reach 5-10x more people than a post with 500 likes but only 3 comments. Facebook interprets comments as evidence that your content is sparking real conversation, and rewards it with massive organic distribution.
