Every YouTube Analytics Metric Explained (2026)
Views, impressions, CTR, traffic sources, watch time, retention, audience, Shorts, RPM and CPM in YouTube Studio, explained in plain language.
On this page
Your videos get views, but people leave in seconds. Why? The clues are already inside YouTube Studio, if you know what each number means.
This guide covers every metric in YouTube Analytics, tab by tab. Definitions come from YouTube’s help pages and the YouTube Analytics API documentation, checked in October 2026. All example numbers are examples, not real data. YouTube has been rolling out an updated Studio design since July 2026, so your screen may look a little different.
Quick answer: the five numbers to check first
| Metric | What it tells you |
|---|---|
| Impressions | How often your thumbnail was shown |
| Click-through rate (CTR) | How often a shown thumbnail became a view |
| Average view duration | How long people who stayed actually watched |
| Audience retention | Exactly where in the video people left |
| Returning viewers | Whether people come back |
Overview tab
The Overview tab is your summary, for the channel or a single video.
- Views: counted from the moment a video starts playing, across long videos, Shorts and live streams.
- Watch time: the total time viewers spent watching, in hours.
- Subscribers: how many viewers subscribed.
- Estimated revenue: for Partner Program members, total net revenue from Google-sold ads and transactions in the date range.
- Average view duration: average minutes watched among viewers who stayed.
- Realtime: early performance of recent videos. Compare the first 60 minutes with the first 48 hours, and filter by videos or Shorts.
- Typical performance: a comparison with your usual numbers, to explain why views are higher or lower. It’s a comparison, not a separate metric.
- Top content and latest content: your most-viewed videos, and a snapshot of the newest one (views, impressions, CTR and average view duration).
Views
| Metric | Meaning |
|---|---|
| Views | Counted from the start of playback; YouTube calls these legitimate views |
| Engaged views | Viewers stayed past the first few seconds; loops aren’t counted |
| Unique viewers | Estimated number of different people who watched in the date range |
| Unique reach | Estimated individual people who saw your video or channel, including shared devices like YouTube TV |
| Co-viewed views | Estimated total views when several people watch together on one device |
YouTube uses engaged views to calculate unique viewers and average view duration.
Reach
Impressions and CTR
An impression counts when your thumbnail stays on screen for more than one second with at least half of it visible.
| Impressions count in | Not counted in |
|---|---|
| YouTube search | Outside websites |
| Home page | YouTube Kids and YouTube Music apps |
| Subscriptions and Trending feeds | Cards and end screens inside the player |
| Up Next | Email and notifications |
| Playlists |
Click-through rate (CTR) is how often viewers watched after a counted impression. Because it uses only counted impressions, views ÷ impressions won’t always match it.
- What’s normal? YouTube says half of all channels and videos have a CTR between 2% and 10%. Search usually brings fewer impressions but a higher rate, and the home page more impressions but a lower rate.
- Don’t read it alone. When reach grows, strangers see your thumbnail, and strangers click less than fans. YouTube’s example: 10,000 impressions at 9% growing to 100,000 at 3.5%, which is far more views.
- Don’t chase it with clickbait. YouTube warns clickbait tends to have low average view duration, so it’s less likely to be recommended.
The impressions and how they led to watch time card shows how impressions became views, then watch time. It’s the quickest way to see where the funnel leaks.

Traffic sources
Traffic sources show where viewers came from, inside YouTube or outside it:
| Source | Where the viewer came from |
|---|---|
| Browse features | Home page, Subscriptions feed, Watch Later, Trending or Explore |
| Suggested videos | Suggestions next to or after other videos, and description links |
| YouTube search | Search results (the search terms card shows what they typed) |
| Channel pages | Your channel page, or other channels’ pages |
| Notifications | Notifications and emails to subscribers, including belled subscribers |
| Playlists | Any playlist with your video, including viewers’ liked videos |
| Shorts | The Shorts feed; sound pages and remixed video are related sources |
| Video cards / end screens | A card or end screen in another video |
| YouTube advertising | Your video running as a YouTube ad |
| External | Websites and apps that embed or link to your video |
| Direct or unknown | Typed links, bookmarks, signed-out viewers, unidentified apps |
Smaller ones include other YouTube features, product pages and campaign cards.
Helper cards in Reach: content suggesting this video, playlists featuring this video, and bell notifications sent (the share of subscribers who get bell notifications). Follow-on views are organic views from people who watched after seeing your promoted content.
Engagement
- Watch time is a total, not an average: 10,000 short views can add up to the same as 1,000 long ones.
- Average view duration only includes people who stayed, so a good number doesn’t mean everyone stayed. Pair it with the retention graph.
- Average percentage viewed is the average share watched among people who stayed. A 10-minute video at 40% means about 4 minutes watched.
Audience retention
The key moments report (single videos only) shows how well each moment held attention. A flat line means people watched that part through, and a gradual slope means interest slowly faded.
| Marker | Meaning |
|---|---|
| Intro | % still watching after the first 30 seconds: the best check on your opening |
| Top moments | Where almost no one dropped off: your best pacing |
| Spikes | Moments rewatched or shared |
| Dips | Moments skipped or where people stopped watching |
| Typical retention | Compared with your 10 latest videos of similar length |
Split retention with the segments drop-down: organic vs paid, new vs returning, and subscribers vs non-subscribers.

Other engagement metrics
- Likes vs dislikes: counts can shift as invalid ones are removed, so Analytics may differ slightly from the watch page.
- Comments and shares: comments posted, and uses of the Share button (definitions from the Analytics API).
- End screen element click rate: how often each end-screen element was clicked (open a specific video to see it).
- Cards: card impressions count when the card panel opens, and card click rate is clicks ÷ impressions.
- Playlists: top public playlists by views, plus playlist starts, views per playlist start and average time in playlist (from the API).
- Top remixed: your content remixed into Shorts, with remix counts and views.
Audience
| Metric | Meaning |
|---|---|
| Monthly audience | Estimated viewers in the past 28 days, recalculated daily |
| New viewers | First watch on your channel in the period (also private browsing, cleared history, or no watch in over a year) |
| Returning viewers | Watched before and came back |
| Casual viewers | Watched at least once a month for 1–5 months of the past year |
| Regular viewers | Watched at least once a month for 6+ months of the past year: your core fans |
| Watch time from subscribers | Share of watch time from subscribers vs non-subscribers |
Also in this tab:
- When your viewers are on YouTube: the last 28 days, handy for scheduling premieres and live streams.
- Device type: watch time split across mobile, computer, TV and tablet.
- Age and gender, top geographies and top subtitle languages.
- Channels your audience watches (past 28 days), good for finding collab partners, and what your audience watches (past 7 days), good for topic and title ideas.
- Formats your viewers watch: videos, Shorts or live streams over 28 days.
Some data, like geography, traffic sources or gender, may be limited.
Content tab
The Content tab filters by type: all, videos, Shorts, live, posts, playlists and podcasts.
- All: how much you published, and how your audience overlaps between formats.
- Shorts: views, likes and subscribers, plus stayed to watch, the share of times viewers stayed past the first few seconds.
- Live: concurrent viewers, the peak and average watching at the same time.
- Posts: impressions, likes and subscribers gained, plus post like rate.
Revenue
- Estimated revenue: total net revenue, including ads, memberships, YouTube Premium and Super Chat. Estimated ad revenue is ads alone.
- RPM (revenue per mille): what you earn per 1,000 views, after YouTube’s share, from all revenue sources. Shorts use engaged views, and videos count all views, including ones without ads.
- CPM: what advertisers pay per 1,000 ad impressions, before YouTube’s share. It only counts views where ads ran.
- Playback-based CPM: what advertisers pay per 1,000 playbacks that showed at least one ad. Often higher than CPM, because one video can carry several ads.
- Ad impressions and estimated monetised playbacks: how many times individual ads were viewed, and how many times your video was watched with ads.
That’s why RPM is lower than CPM: it’s after YouTube’s share, and it includes views that earned nothing. They answer different questions, so don’t compare one to the other.
YouTube’s own example:
| Input | Value |
|---|---|
| Views | 5,000 |
| Views with ads | 1,500 |
| Ad impressions | 2,000 |
| Advertiser payment | $7 |
| CPM ($7 ÷ 2,000 × 1,000) | $3.50 |
| Playback-based CPM ($7 ÷ 1,500 × 1,000) | $4.67 |
These are estimates and can change. Finalised earnings appear in AdSense, usually around the 7th to 12th of the following month, and tax withholding shows only in AdSense. The creator business terms guide explains the payment side.
Coming soon: RPM vs CPM on YouTube, what you actually earn.
Trends and advanced mode
- Trends shows what viewers across YouTube are searching for, which can reveal content gaps and ideas for long videos and Shorts.
- Advanced mode gives expanded reports, comparisons and data export when the standard cards aren’t enough.
Reading the numbers together
| Pattern | What it usually means |
|---|---|
| Impressions up, CTR down | You reached strangers. If average view duration holds, you’re fine. |
| High CTR, low average view duration | The packaging promised more than the video delivered. Check the first 30 seconds. |
| A spike in retention | Something worth rewatching. Make more of it. |
| Many new viewers, few returning | You’re discovered but not building a habit. Think series and a schedule. |
| Views up, revenue flat | Check RPM and your revenue sources. |
Five mistakes to avoid
- Judging a video by CTR alone.
- Chasing CTR with clickbait.
- Reading average view duration without the retention graph.
- Comparing RPM with CPM.
- Treating estimated revenue as final money.
Try it: open Studio, find the biggest dip in your latest video’s retention graph, and fix that moment in your next video.
