The key is understanding that the algorithm no longer rewards quantity but genuine conversation, the most important metric now isn't likes, but comments and the number of times people share your post via private message, so your content needs to encourage people to share their opinions, ask questions, or discuss.
An easy way to improve is to ask specific questions in your posts, instead of asking what do you think?, ask something like which of these two methods do you use? or has this ever happened to you? this generates much more engagement than a generic phrase, posts that tell a personal story or share a mistake you made also work very well because people connect with the human element and are more willing to share their own experiences.
Short video formats are also a priority, facebook is heavily promoting reels, even more so than images, if you can show something in motion, do it, a well edited 15 second video with on screen text usually has a much wider reach than a carefully curated photo, and don't forget to respond to comments quickly, because that tells the algorithm your post is generating engagement and shows it to more people, ultimately, quality on facebook today is synonymous with content that gets people talking and feeling like they're part of something, not just pretty, soulless posts.
