Reach
Reach is the number of unique people who saw a piece of content at least once, counting each person a single time no matter how often they viewed it, which makes reach always equal to or lower than impressions.
Reach answers a different question than impressions: not how many times the post was shown, but how many distinct humans it got in front of. Because each person is deduplicated, reach is the honest audience-size number. The gap between the two is itself informative — impressions running far ahead of reach means a smaller group is seeing your post repeatedly, which often happens when a post keeps resurfacing in an engaged sub-network rather than breaking into new feeds.
LinkedIn's reporting makes this harder than it should be. The platform surfaces different labels in different places — post-level analytics, the creator dashboard, and CSV exports have not always used the same wording or the same time windows — and it does not publish a full methodology for how a unique viewer is identified across sessions, devices, and logged-out views. Treat any single reach figure as directionally useful and comparisons across LinkedIn surfaces as suspect unless you know both numbers came from the same report.
For content strategy, reach is the metric to watch when your goal is finding new people, and impressions is the metric to watch when your goal is frequency against an existing audience. Most people building authority on LinkedIn need both: enough reach to keep the pool growing, and enough repeat exposure that the same buyers see your name often enough to remember it. A month of high impressions with flat reach means you are talking to the same room louder.
