It happens every year or two on every network. Reach drops, everyone posts about how it is over, and a wave of advice arrives about what the algorithm now wants.
First, check it is real
Compare a month to a month, not a week to your best week. Seasonal dips look identical to algorithm changes from inside a single account, and most reported changes are the former.
The advice wave is mostly wrong
Nobody outside the company knows what changed. What circulates afterwards is inference from a handful of accounts, presented with confidence because confidence is what gets shared. Following it usually means abandoning what worked for what somebody guessed.
What actually helps
- Keep posting at the same rate — a dip plus a pause becomes a decline
- Change one thing at a time, so the result means something
- Check the account status page: sometimes the answer is specific and about you
- Look at where reach comes from, not just how much — the shape of the drop says more than its size
The accounts least hurt by platform changes are the ones with somewhere else to reach people: a mailing list, a Telegram channel, a customer who knows your name. That is the only real hedge there has ever been.
