You have a table with a row for each platform, a column called views, and a total at the bottom. Every figure came out of the platform itself, so nothing above the last cell is wrong. The last cell is wrong, because the numbers it adds are not counts of the same event.
The number at the bottom of the table
That is a unit problem rather than a data quality problem. Each platform’s figure measures whatever that platform documented, and the documents describe different events, so the sum is an arithmetic error dressed as a summary.
Everything quoted below comes from the platform’s own help or developer documentation, retrieved on 2026-08-25. Where a document could not be read on that date, the platform is left out rather than described from someone else’s summary. The platforms covered are YouTube, Instagram by way of Meta’s Instagram Platform insights documentation, and LinkedIn by way of its own marketing API documentation. TikTok is not covered, for a reason set out near the end. That is the scope and it is a limit.
YouTube changed what a view is, and dated the change
YouTube’s help page on how engagement metrics are counted opens with the definition and dates it: “Beginning August 24, 2026, views are counted the moment a video starts to play across all formats, including Shorts, long-form videos (VOD), and live streams.” That sentence was on the page at support.google.com/youtube/answer/2991785 when it was read on 2026-08-25. Figures either side of that stated effective date were produced under different rules.
The same page keeps other named metrics separate from that one. It says the update “won’t impact your YouTube Partner Program (YPP) earnings or eligibility”, that YPP earnings “will still be based on ‘engaged views’ and ‘engaged watch hours’”, and that YPP eligibility “will still be based on ‘qualified views.’” Those are the page’s terms, not defined further there or here. The number shown as views is not the number the partner program runs on.
A thumbnail impression is a third documented event. YouTube’s page on thumbnail impressions and watch time describes the metric as “How many times your thumbnails were shown to viewers on YouTube through registered thumbnail impressions”, and states the condition: “Impressions are counted if the thumbnail is shown for more than 1 second and at least 50% of the thumbnail is visible on the screen.” That page, at support.google.com/youtube/answer/9314486, read the same day, is about impressions and watch time. It is not YouTube’s definition of a view.
The definition says when the count happens, nothing about duration or completion, and duration sits in a separate metric called watch time. The same discipline applied elsewhere is the method behind reading a platform document critically.
Meta’s documentation counts times, and then counts people
Meta’s Instagram Platform insights guide prints the description string returned with each account metric. Read at developers.facebook.com/documentation/instagram-platform/insights on 2026-08-25, impressions is described as the “Total number of times the Business Account’s media objects have been viewed”, reach as the “Total number of times the Business Account’s media objects have been uniquely viewed”, and profile views as the “Total number of users who have viewed the Business Account’s profile within the specified period”.
The unit moves inside a single document. The first two count times. The third counts users. A metric whose unit is an event and one whose unit is a person cannot be compared by size, and a ratio across that boundary has a denominator nobody could name. Reading the document first is the habit behind what Instagram has actually published.
The same page carries a limitation that matters the moment a post has money behind it. It says metrics “such as comments, likes, and views return engagement on the target Instagram media only and don’t include data from other surfaces”. It says to use “total_comments, total_likes, and total_views on the Insights endpoint to get aggregated counts that include engagement from promoted/boosted/ad media”, and that “These total metrics are only available for Instagram API with Facebook Login.” A figure pulled for a boosted post from the media metric is the organic surface only, by documented design, with the aggregate under a differently named field.
Instagram’s creator facing help page on insights returned a page with no readable body text when it was fetched on 2026-08-25, so nothing here is attributed to it. Every quotation above comes from Meta’s own developer documentation.
LinkedIn’s own documentation does not list a view at all
LinkedIn’s marketing API documentation for organizational entity share statistics sets out a Share Statistics Data Schema, field by field. Read on 2026-08-25, it lists impressionCount as “Number of impressions”, uniqueImpressionsCount as “Number of unique impressions”, engagement as “Number of organic clicks, likes, comments, and shares over impressions”, and counts of clicks, comments, likes and shares.
There is no views field in that schema. For organic share statistics, LinkedIn documents impressions. A LinkedIn figure sitting in a column headed views has been renamed by whoever built the table, not by LinkedIn.
The harder point is what the description does not say. “Number of impressions” names the unit and stops. It does not say what event registers an impression, how much of the post has to be on screen, or for how long. YouTube publishes a threshold and a duration for its thumbnail impressions. LinkedIn’s gap is real and is better left open than filled with a definition borrowed from another platform.
The definitions side by side
| Platform | Term the document uses | What the document says is counted | Events or people | Retrieved |
|---|---|---|---|---|
| YouTube | views | “views are counted the moment a video starts to play across all formats, including Shorts, long-form videos (VOD), and live streams” | Events, at the start of playback | 2026-08-25 |
| YouTube | thumbnail impressions | “How many times your thumbnails were shown to viewers on YouTube through registered thumbnail impressions” | Events | 2026-08-25 |
| impressions | “Total number of times the Business Account’s media objects have been viewed” | Events, described as times | 2026-08-25 | |
| reach | “Total number of times the Business Account’s media objects have been uniquely viewed” | Events, described as times, uniquely | 2026-08-25 | |
| profile_views | “Total number of users who have viewed the Business Account’s profile within the specified period” | People | 2026-08-25 | |
| impressionCount | “Number of impressions.” | The document does not say what event is counted | 2026-08-25 | |
| uniqueImpressionsCount | “Number of unique impressions.” | The document does not say what event is counted | 2026-08-25 |
This is a table of quoted definitions and nothing more, not a reporting layout.
Why TikTok is not in this piece
TikTok’s own support, developer and newsroom documentation could not be retrieved from this environment when it was attempted on 2026-08-25, so how TikTok counts is not described here. The rule behind the omission is the rule behind everything above: a definition is either quoted from the platform that issued it, on a stated date, or it is left out. A third party paraphrase is not a primary source.
What this changes about the figure you hand over
A single number produced by adding view or impression counts across platforms is not a total. The addends are counts of different documented events, and in one case a count of people rather than events, so the result has no unit anyone could name.
What survives scrutiny is naming. Report each platform’s figure under the term that platform’s documentation uses, and say what that term counts, in the document’s words, with the date read. YouTube views counted at the start of playback. Instagram impressions as times media objects have been viewed. LinkedIn impressions, unqualified, because the schema leaves the event undefined.
Separately, a single platform can report figures for the same post that do not agree with each other, which is a question about that platform’s own reporting rather than about what the unit means. The definitions are published, dated and quotable, so what a number counts can be settled by reading and noting the date, and the question after that points outward, to where industry averages come from.
FAQ
Can I add views across platforms if I label the total clearly
No, and the reason is the unit rather than the presentation. A label describes a number, it does not change what the number counts. The quoted definitions in the table above count different events, and one of them counts users, so the addition has no shared unit for a label to name honestly.
Does a view mean someone watched the video
Going only by the wording, YouTube counts a view the moment a video starts to play, which tells you playback began and nothing about how long it continued. The other documentation quoted here does not describe watching at all. Meta’s descriptions count times media objects have been viewed and users who have viewed a profile, and LinkedIn’s schema does not say what event an impression is.
Is an impression the same thing as a view
Not across these three documents. YouTube’s thumbnail wording states a threshold and a duration, counting an impression when the thumbnail is shown for more than 1 second with at least 50% of it visible. Meta’s impressions description counts times media objects have been viewed. LinkedIn’s schema gives “Number of impressions” and never says what event that is. None of the three documents says its term means what another’s means.
Where do I find these definitions myself
YouTube publishes the view definition on its Help page about how engagement metrics are counted, and the thumbnail wording on its Help page about thumbnail impressions and watch time. Meta publishes the metric descriptions in the Instagram Platform insights documentation, and LinkedIn the schema on its marketing API page for organizational entity share statistics. All are linked below. Record the date you read each one, because the YouTube definition carries a stated effective date.
Why is TikTok not covered
Because TikTok’s own documentation could not be retrieved from this environment on 2026-08-25, and a definition is not paraphrased from a third party into a piece that quotes every other definition from the document that issued it.
