Complicated all these algorithms... Let's try to learn more about the Facebook one!
Let's try to demystify all this because it's not really obvious! And it changes all the time! You all know it, Facebook is the boss! He decides who sees your publications and who doesn't.
Facebook's algorithm is getting smarter and smarter. That's why it's important to post at the right time. If for example you publish the image of a crossant at 8:00 pm, you are unlikely to publish a lot... Facebook analyzes absolutely everything! And selects the content according to the time of day but also according to what the person likes. That's also why sometimes some publications are displayed the next day on the news feeds.
Of course, there is also the question of the user's "commitment" to the page. But that's no secret for anyone either. The more commitment you have to the page, the more Facebook will post it on the news feeds. And as you all know, Facebook prefers videos to simple text or photos. But in terms of commitment, it favors comments over likes.
To conclude, you need to produce content (video or live, the Holy Grail) that provokes engagement at the right time and when your subscribers are online. These are the main parameters to take into account.
