Ask most people how a post did and they tell you the like count. It is the wrong number, and worse, it is a late one. By the time the likes are in, the post has already done whatever it was going to do. You learned nothing you can use on the next one.
Reach is decided early
A post gets shown to a small slice of your network first. What that slice does in the first stretch decides whether the platform shows it to more people or quietly buries it. The total at the end is just the outcome of that early test. The signal you want is the test result, not the final score.
Time-to-peak is the tell
The number that runs ahead of reach is how fast engagement arrived. A post that catches in the first hour is telling the platform it is worth distributing. A post that trickles in over two days, even to the same final total, never sent that signal. Same likes, completely different reach, and the difference was speed.
- Watch the first hour, not the final tally. Early velocity is the leading indicator.
- A fast start with a modest total often out-travels a slow start with a bigger one.
- Compare a post to its own early curve, not to a monthly average that hides every spike.
What this changes about how you write
If early velocity is the lever, then everything that gets a reaction faster matters more than everything that gets a bigger reaction eventually. The cold open that pulls the reader in. The post that ends on the landing line. The team that shows up in the first hour. These are not separate tactics. They are all the same bet on speed.
How buyWords surfaces it
Per-post analytics reads time-to-peak and the engagement-pattern shape behind the posts that performed, so you can repeat the shape and not just the topic. Team Advocacy exists for the same reason: the first hour is where distribution is won, so we built a system to make sure the team is there for it.
