What the numbers mean, what they hide, and what to tell the person who asks.
Reach is not one number. Engagement rate depends entirely on who is counting. Most published benchmarks trace back to somebody’s blog post rather than a dataset anyone can inspect. The pieces here quote each platform’s own definitions, show the same campaign measured more than one way, and give you a method you can repeat on your own account.
The emphasis is on what to do when the numbers disagree, and on what to say to a founder or a client who has asked for the industry average. No analytics tool roundups, no invented benchmark tables, and no scolding about vanity metrics without evidence behind it.
