In my experience, simple and relatable posts work best. People love sharing opinions, personal experiences and answering genuine questions. A good conversations starter usually gets more replies than a perfect looking post. Engagement comes from connection, not just content.
In my experience, posts involving general and informational questions which allow people to engage generate the most responses.
Oddly enough, simple opinions works mch well for me because uhh need to give your readers an opportunity to disagree with you.
In my point of view, Short-form FB Reels drive the most reach, but raw, unfiltered text questions generate the highest comment velocity.
