PostEaseThe short answer
Reach is the number of different people (unique accounts) who saw a post. Impressions are the number of times it was shown, so one person seeing it three times is one of reach and three impressions. Impressions are therefore always at least as large as reach. On Instagram and Facebook, Meta replaced impressions with a metric called views in November 2024, counted the same way: every time a post appears on a screen, repeat views included.
Reach, impressions and views compared
The three numbers answer different questions.
| Metric | What it counts | One person sees a post three times | Use it to |
|---|---|---|---|
| Reach | Different people who saw it | Counts 1 | Know how many people you got in front of |
| Impressions | Times it was shown | Counts 3 | Know how often it was displayed, including repeats |
| Views (Meta) | Times it was played or shown | Counts 3 | The same, on Instagram and Facebook since late 2024 |
What Meta changed in 2024
Meta announced on 14 November 2024 that a new metric, views, would replace impressions for stories, photos and text posts, and replace plays for Reels and videos, on both Facebook and Instagram. A view is counted each time a reel or video is played, or a photo or text post is shown on screen. Meta’s own example: if someone looks at the same photo three times in a day, that is three views, where it used to be one impression. Reach stayed as it was.
| Content | Old metric | Now |
|---|---|---|
| Reels and videos | Plays | Views, calculated the same way |
| Stories, photos and text posts | Impressions | Views, counting repeat views |
| All content | Reach | Reach, unchanged |
Which one to use
Use reach when you want to know how many people a post got in front of, and for engagement rate, since dividing by reach counts each person once, which is how Buffer’s 2026 engagement report calculates it. Use impressions or views when you want to know how much attention a post kept getting, since a post people come back to piles up views without adding reach.
The gap between the two is informative. Views far above reach mean people saw the post more than once, through repeat visits, shares or a long run in the feed.
YouTube counts impressions differently
On YouTube, an impression is a thumbnail registered as shown on YouTube, and YouTube Help notes that not every sighting of a thumbnail counts. Impressions on other websites and on end screens are not counted, so impressions click-through rate covers only part of a channel’s views.
Questions
Can impressions be lower than reach?
No. Every person reached saw the post at least once, so impressions (or views) are always at least as large as reach.
Did Instagram remove impressions?
Yes. Meta replaced impressions with views for stories, photos and text posts, and plays with views for Reels and videos, on Instagram and Facebook, announced on 14 November 2024. Reach was unchanged.
Is reach or impressions more important?
Reach, for knowing how many people saw your work and for engagement rate. Impressions or views, for knowing how much attention a post kept getting.
Why are my views so much higher than my reach?
Because views count repeat showings. People who saw the post more than once, or saw it again after a share, add views without adding reach.
