Some practices that could hurt your FB algorithm

1-Joining lots of groups you can't engage in.

You only need a little number you can engage meaningfully with their contents and not those you will have to mute or keep ignoring notifications from them. ⁣

Also stay away from Markets groups where everyone goes to promote their stuffs especially those groups where people spam one another. You may also be marked spam⁣

2-Adding too much friends you have nothing in common with. You will keep skipping their posts and they won't also engage with yours.⁣

This will affect your reach as you will end up adding a bunch of inactive friends as many people will not see your post due to lack of engaments.⁣
