Does posting daily on LinkedIn actually help?

Yeah, it can help, but daily posting isn’t magic. Consistency + useful content matters more than frequency. I’d rather post 3–5 solid posts a week than force a low-quality post every day.

in my experience there is definitely a limit. if you post more than once every 24 hours you end up killing the reach of your previous post before it even peaks. the algorithm needs time to test the content with a small group first. three or four times a week is usually plenty, anything more and you just end up spamming your network tbh.

I don't know—anyway, I use my account every day to play little games, follow people, post, and comment on things, though I'm not sure if any of it actually does anything.
