Full definition
Impressions count every time a post appears on a user's screen, even if that same user sees it multiple times. This differs from Reach, which counts only unique people. Impressions is the most basic exposure metric.
📌
Why it matters
Impressions are the denominator under almost every other metric. Without knowing how many people saw something, a count of clicks or comments means nothing.
🧮 A worked example
Two posts each got 30 comments. The first reached 800 people, the second 9,000. The first performed eleven times better, but in a report showing only comments they look identical.
⚠️ The common mistake
Treating impressions as people. Someone who scrolled past your post three times counts three times in impressions and once in reach.
