Reach
Reach is the number of unique LinkedIn accounts that saw a given post at least once. It is different from impressions, which count every time the post loaded on a screen, including repeat views from the same person.
What it actually means
Reach counts people, not views. If 4,000 unique accounts saw your post, your reach is 4,000, regardless of whether some of them scrolled past it twice in their feed. Impressions count events, not people. If those same 4,000 accounts generated 6,500 total views because some saw it more than once, your impressions are 6,500. LinkedIn's own analytics panel reports both numbers separately for exactly this reason: they answer different questions.
Why it matters to someone selling
Reach tells you how far a post traveled. That matters because distribution is the first constraint on any content-driven pipeline effort. You can write the sharpest post in your niche, but if the algorithm only pushes it to 300 people, it cannot generate meetings. A reach strategy, built through consistent posting and format discipline, is what turns a single piece of content into a recurring source of inbound attention rather than a one-off (chrysales.com/post/linkedin-reach-strategy-b2b-posts). Without reach, nothing downstream happens.
The misconception
The mistake is treating reach, or impressions, as a proxy for buying intent. Neither number tells you who is in-market, who has budget, or who is even paying attention rather than thumb-scrolling past. A post can rack up huge reach because it triggered outrage, nostalgia, or a meme format, and generate zero commercial interest. Sellers who report reach or impressions to their manager as a pipeline indicator are reporting exposure, not demand. Reach is necessary for pipeline to exist. It is not sufficient, and it is not evidence that anyone is closer to buying.
How it's really used
Use reach to diagnose distribution problems: is the algorithm suppressing this format, this posting time, this topic. Use it to compare posts against each other over time to see what your network rewards with visibility. Do not use it to forecast revenue. The number that actually correlates with pipeline is what happens after reach: comments from the right titles, profile visits from target accounts, DMs, connection requests from people who match your ICP. Reach gets you in front of people. Everything that indicates intent happens after that, and it has to be tracked separately.
