Reach vs impressions vs views: what 8 platforms count in 2026

By the Postora editorial teamUpdated 12 min read

Short answer

Reach vs impressions: reach counts people, the unique accounts that saw your content at least once. Impressions and views count displays, so one person who sees a post three times adds three. Display counts can be added across platforms under a label. Reach cannot.

The words are shared across platforms. The definitions are not. Meta now calls its display count "views" on Instagram, Facebook and Threads, and Instagram and Threads call the unique count "viewers". LinkedIn and Pinterest still report impressions. YouTube has changed what a view is twice since March 2025. The glossary below comes from each platform's own help pages and developer docs, read on 2026-09-28, with the date of the last definition change wherever the platform published one.

What is the difference between reach, impressions and views?

  • Reach counts people or accounts. Each one is counted once, however many times they saw the content. The name varies: viewers (Instagram, Threads), reach (Facebook, and the Instagram API), members reached (LinkedIn), total audience (Pinterest), unique viewers (YouTube).
  • Impressions count displays: every time the content came on screen. What "on screen" means varies. YouTube counts a thumbnail impression only when the thumbnail is shown for more than one second with at least half of it visible. LinkedIn's definition says only that the post "was shown".
  • Views now mean two different things. On Instagram, Facebook and Threads a view is any play or display; on Instagram and Facebook it replaced both impressions and plays. On YouTube and in LinkedIn's video analytics, a view is a video play: YouTube counts it at the start of play, LinkedIn after more than 2 seconds. TikTok's creator analytics guide does not say how an organic view is counted.

One derived number is worth keeping. Views or impressions divided by reach gives the average number of times each person saw the content. A ratio of 4.0 means the people reached saw it four times each on average. A ratio near 1.0 means most saw it once.

What does each platform count as reach, impressions and views?

"Repeats" means the same person is counted each time. "Unique" means each person or account is counted once. "Not dated" means the platform's help page and developer docs give no date for the current definition.

Platform Metric (name in the app) Counts What the platform says it counts Last dated definition change Add across platforms?
Instagram Views Repeats Times content was played or displayed. Includes reels, posts, stories, live videos and ads. API: views added and impressions and plays deprecated in v22.0 (2025-01-21), for all versions from 2025-04-21 Yes, in a labelled display total
Instagram Viewers (API: reach) Unique Unique accounts that saw the content on screen at least once; for reels, whether or not the reel played. Estimated. Not dated No
Facebook Views Repeats Reel and video plays, plus the times photos or text were on screen. Includes ads. Plays were relabelled as views. App: October 2024. Page Insights API: impressions replaced by views on 2025-11-15 Yes, in a labelled display total
Facebook Reach Unique Reach from organic and paid distribution, tags, check-ins and profile visits, counted once if it came from both organic and paid. Estimated. API: page and post unique-impression metrics marked "Deprecated above Graph API v25" No
Threads Views Repeats Total views of your content, from followers and non-followers. API: times a post was played or displayed. Not dated Yes, in a labelled display total
Threads Viewers Unique Unique Threads profiles that saw the post at least once. Not dated No
TikTok Post views Not stated Not defined in TikTok's creator analytics guide. The Display API field reads "Number of views of the video". TikTok's ads help defines a video view as a start of play, replays excluded. Not dated Only as TikTok's own count, labelled
TikTok Viewers Unique TikTok Studio's Viewers page shows unique and returning viewers for the selected period. Not dated No
LinkedIn Impressions Repeats Times the post was shown on LinkedIn. An estimate. Not dated Yes, in a labelled display total
LinkedIn Members reached Unique Distinct members and Pages that saw the post, repeat displays excluded. An estimate. Not dated No
LinkedIn Video views Repeats Times the video was watched for more than 2 seconds, sponsored and organic. Not dated Only into a labelled video total
YouTube Views Repeats Counted the moment a video starts to play, in every format. Shorts views have counted replays since 2025-03-31. 2026-08-24 (all formats); 2025-03-31 (Shorts) Yes, in a labelled display total
YouTube Impressions Repeats Thumbnail shown for more than 1 second with at least 50% visible. Not counted on external sites and embeds, in cards or end screens, on the mobile website, in YouTube Kids or YouTube Music, or in email and notifications. Not dated Yes, but not together with YouTube views
YouTube Unique viewers Unique Estimated number of people who watched in the date range, across devices. Periods of up to 90 days. Not dated No
Pinterest Impressions Repeats Times your Pins or ads were on screen. Real-time figures are estimates and can go down. Not dated Yes, in a labelled display total
Pinterest Total audience Unique People who saw or engaged with your Pins. Not dated No
X Views Repeats Times a post was viewed by logged-in users, the author's own views included; embedded posts do not add. The API's public metrics combine organic and promoted. Not dated Yes, in a labelled display total
X No reach metric n/a Neither X's help page nor its API metrics docs define a reach count for posts. The API's only unique figures are non-public video playback quartiles: unique users who played through 0, 25, 50, 75 or 100% of a video. n/a n/a

Three rows need a comment.

  • X calls a repeat count "reach". Its help page says view counts show "the reach of your posts", and the same page says "not all views are unique": a post seen on the web and then on a phone counts twice. X's API docs say the same of impressions: "the same user viewing twice counts as two impressions." Report X views as a display count.
  • TikTok does not publish how an organic view is counted. The video play metrics page in TikTok's Business Help Center excludes replays, but it documents campaign reporting for advertisers. TikTok's Creator Academy guide to analytics lists post views without saying how a view is counted. Label the figure "TikTok post views" and do not assume it matches the ads rule.
  • LinkedIn counts Pages in "members reached". The Page analytics help defines it as "distinct members and Pages". It is not strictly a count of people.

When did the definitions change?

Every date below is from the platform's own changelog, developer blog or help page.

  • October 2024. Facebook adds a views metric to Meta Business Suite and the professional dashboard. For reels and videos, plays are relabelled as views.
  • 21 January 2025. Graph API v22.0 adds views to Instagram media and user insights and deprecates impressions, plays, clips_replays_count and ig_reels_aggregated_all_plays_count. The change applies to all API versions from 21 April 2025. After that date, requests for impressions on media created on or after 2 July 2024 return an error.
  • 31 March 2025. YouTube counts a Shorts view "the number of times a Short starts to play or replay, with no minimum watch time requirement". The previous measure is renamed engaged views.
  • 15 November 2025. Facebook's Page Insights API replaces impressions with views on all API versions. Meta announced it on 15 August 2025 with 90 days' notice, and deprecated the page fans metrics at the same time.
  • By 15 June 2026. Meta's Page Insights reference states that "a number of the Page Insights metrics will be deprecated for all API versions" and that calls to them return an invalid metric error. The page and post unique-impression metrics are marked "Deprecated above Graph API v25". A unique count the reference lists for Pages is page_total_media_view_unique, "the number of total unique media viewers".
  • 24 August 2026. YouTube counts a view "the moment a video starts to play across all formats, including Shorts, long-form videos (VOD), and live streams". YouTube Partner Program earnings are still based on engaged views and engaged watch hours.

Any series that crosses one of these dates has a break in it. A chart that sets 2024 Instagram impressions next to 2025 Instagram views compares two metrics, since views replaced both impressions and plays. The same goes for YouTube views on either side of 24 August 2026.

Can you add reach, impressions and views across platforms?

Three rules cover it.

  1. Display counts add up under a label. Instagram views, LinkedIn impressions and X views are all counts of displays, so their sum is a fair measure of volume. The thresholds differ (a YouTube thumbnail needs more than a second on screen, LinkedIn's post only needs to be "shown"), so the total is not a count of anything uniform. Label it as what it is.
  2. Unique counts never add up. Not across platforms, because one person can follow a brand on two of them. Not across posts: YouTube's unique viewers page says a viewer of several videos is a unique viewer for each video but "those views will be combined into one unique viewer for your channel". Not across weeks, because the same people come back.
  3. One platform, one display count. YouTube impressions count thumbnails, and YouTube views count plays. A person who saw the thumbnail and then played the video appears in both, so adding them counts that person twice.

A worked example

The figures below are an illustration, not data. A café's September report covers three platforms.

Platform Display count Unique count Views per viewer
Instagram 12,400 views 3,100 viewers 12,400 ÷ 3,100 = 4.0
Facebook 5,200 views 2,300 reach 5,200 ÷ 2,300 ≈ 2.3
LinkedIn 900 impressions 610 members reached 900 ÷ 610 ≈ 1.5
Report line 18,500 views and impressions 3,100 to 6,010 people Per platform only
  • Display total: 12,400 + 5,200 + 900 = 18,500. Print it as "views and impressions, as each platform counts them".
  • People: the unique counts sum to 3,100 + 2,300 + 610 = 6,010. That is a ceiling, reached only if nobody saw the café on two platforms. The floor is 3,100, the largest single figure. The true number of distinct people lies between the two, and no platform can tell you where. Print the range, or print each platform on its own line with no total.
  • Weeks: if Instagram shows 1,200, 1,000, 900 and 1,100 viewers for four consecutive weeks, those 28 days reached at most 4,200 accounts and usually fewer. Summing weeks also misses the last two days of a 30-day month. Take the monthly figure from Instagram for the month (3,100 here). YouTube gives unique viewers for periods of up to 90 days, which is shorter than at least three of the four calendar quarters (91 or 92 days), so a full-quarter unique count is usually out of reach.
  • Ratios: compare each platform's views per viewer with its own earlier months, not with the other platforms. Instagram and Facebook views include ads, so a month with a boosted post is not comparable with a month without one unless the report says so.

How should a client report label these metrics?

A report that says "reach: 6,010" in the example above states a number of people that nobody measured. The fix is in the labels.

Report line What goes in it Label to print
Displays One display count per platform: Instagram, Facebook and Threads views; LinkedIn and Pinterest impressions; X views; TikTok post views; YouTube views "Views and impressions, as each platform counts them"
People Each platform's unique count, one row per platform, no total The platform's own name: "Instagram viewers", "Facebook reach", "LinkedIn members reached", "YouTube unique viewers"
Frequency Display count ÷ unique count, per platform "Average views per viewer (Instagram)"
Thumbnail impressions YouTube impressions, kept apart from YouTube views "YouTube thumbnail impressions"

Then add four notes under the table.

  1. Definitions. One line per metric with a link to the platform's own page. The glossary above gives the wording and the links.
  2. Breaks. Name any definition change inside the period or inside a comparison, for example: "YouTube counts views from the start of play since 24 August 2026. Figures before and after that date are not comparable."
  3. Paid and organic. Say which figures include ads. Instagram and Facebook views in the apps include ads; Facebook reach includes boosted posts, and the Instagram API's account reach includes ads. In the Instagram API's media insights, per-post views counts organic plays only and total_views adds ads and Facebook views. X's API docs give public metrics as a combined organic and promoted total. LinkedIn's video views include sponsored views, while its API share statistics are organic only. Pinterest impressions cover "Pins or ads".
  4. Data date. Meta's Instagram API docs say data "may be delayed up to 48 hours", and Pinterest says its real-time figures "might decrease". Pull the numbers on a fixed day after the period ends and print that date.

Agree these labels before the first report, in the same conversation as access and approvals; our client onboarding checklist has a line for it. Platform metrics stop at the click. For what happens on the client's website, tag every link with a UTM convention that GA4 sorts correctly, as set out in UTM parameters for social media in GA4.

If a tool assembles the report, check which platform metric sits behind each column. A column headed "impressions" for Instagram posts published after 1 July 2024 cannot be a current pull of Meta's impressions metric, because the API has returned an error for those posts since 21 April 2025. It is either views under an old name or the tool's own estimate, so ask which.

Frequently asked questions

Why are my Instagram views higher than my viewers?

Views count every play or display. Viewers count each account once. Instagram's insights help says views "may include multiple views of your reel by the same accounts". Views divided by viewers is how many times, on average, each account saw the content.

What happened to impressions on Instagram?

Meta replaced them with views. In the Graph API, v22.0 deprecated impressions and plays on 21 January 2025, and the change reached all API versions on 21 April 2025. The Instagram app's insights now show views and viewers.

When does YouTube count a view?

Since 24 August 2026, the moment a video starts to play, in every format. Shorts moved to this rule on 31 March 2025. YouTube Partner Program earnings are still based on engaged views and engaged watch hours.

Does X show reach?

Not as a unique count. X's help page says view counts show "the reach of your posts", but the same page says not all views are unique, and X's API docs define impressions as not unique. Neither defines a reach count for posts; the API's only unique figures are video playback quartiles, which count viewers who reached a point in a video, not everyone who saw the post.

Can I compare this year's views with last year's impressions?

Not as one series. On Instagram, views replaced two metrics (impressions and plays), and on Facebook, plays were relabelled as views before the API dropped impressions. Print the old and new metrics as two series with the change date between them.
