The four-stage funnel
Every view passes through four gates. Growth stops at whichever one is narrowest, and fixing any other gate changes nothing.
| Stage | Metric | Healthy range | If it is low |
|---|---|---|---|
| 1. Shown | Impressions | Growing month over month | Topic or packaging problem — nobody is being offered your video |
| 2. Clicked | Click-through rate | 4–10% for most channels | Thumbnail and title problem |
| 3. Held | Average view duration / AVP | 40%+ on long-form | Hook and pacing problem |
| 4. Returned | Returning viewers | Rising over time | Format inconsistency — no reason to come back |
Diagnosis 1: impressions are flat or falling
This is the hardest one, and the most common on small channels. Low impressions mean YouTube is not offering your video to anyone — either because your topic has no search demand, or because previous videos performed poorly enough that the system stopped testing you widely.
- Check Traffic sources. If 'Browse features' and 'Suggested videos' are near zero, you are invisible outside search.
- Search your own topics on YouTube. If nothing recent ranks, there may genuinely be no demand.
- Make one video on a topic with proven search volume, even if it feels obvious. You need a signal to work with.
Diagnosis 2: impressions are fine, CTR is low
People are being shown your video and choosing something else. This is the fastest problem to fix and the most commonly ignored.
- Shrink your thumbnail to the size of a postage stamp. If it is unreadable, it is failing on mobile.
- Cut thumbnail text to three words maximum.
- Make sure the title and thumbnail say different things — together they should form a complete idea, not repeat one.
- Compare against the videos that actually appear next to yours, not against your own back catalogue.
Work out what your click-through rate would need to be to hit a target view count.

Open any video's retention graph. The shape tells you almost everything.
| Graph shape | Meaning | Fix |
|---|---|---|
| Steep drop in first 30s | The intro is not delivering what the title promised | Cut the intro entirely; start at the payoff |
| Steady decline throughout | Normal, if gentle. Steep means pacing | Tighten edits, remove tangents |
| Sharp mid-video cliff | A specific segment is losing people | Find the timestamp and cut it |
| Flat then cliff at the end | Healthy — viewers left after the payoff | Nothing to fix; add an end screen earlier |
| Spikes upward | People re-watching a section | Make more content like that section |
Diagnosis 4: individual videos do well, the channel does not
This is a format problem. Viewers enjoyed one video but found nothing recognisable to come back for. Check the returning-viewer count and the subscriber-conversion rate per video.
- Pick your best-performing video and make three more in exactly that format.
- Make your thumbnails visually consistent so returning viewers recognise you instantly.
- Put a genuine reason to subscribe in the video, tied to what the next one will be.
Things that are almost never the problem
- Tags. They have negligible effect on discovery.
- Upload time, unless it is wildly wrong.
- Video length in itself — retention percentage matters, duration does not.
- 'Shadowbanning'. Nearly always low CTR or low retention with an emotional explanation attached.
- Camera quality, past a basic threshold.
