What we tested

Conventional beliefs about YouTube — does each apply to this channel?

Conventional wisdom about YouTube is usually true on average. The interesting question is whether it's true on thischannel. Each card tests one belief against this channel's data and reports agrees, disagrees, inconclusive, or not currently testable.

  • Beliefnot currently testable
    Older channels become less dependent on algorithmic recommendations.

    This belief depends on data not currently tracked: cross-channel cohort data. It would activate when more channels contribute their data.

    How this is computed
    algorithmic_dependency_index (1 − sticky_traffic_ratio) vs channel age.
    Cross-channel cohort-level negative correlation at r ≤−0.4.

    n = 2, low confidence.

    How this is computed
    Per video, fit a piecewise function to the impression-by-day curve.

    This belief depends on data not currently tracked: owner-mode-only data (subscribed-state, search queries, etc.). It would activate when the channel owner connects private analytics.

    How this is computed
    Browse views / Browse impressions broken out by subscribed state. Agrees
    if subscribed-state share of Browse views ≥50%.
    

    Source: Common assertion; conflicts with documented YouTube guidance.

  • Beliefnot currently testable

    This belief depends on data not currently tracked: cross-channel cohort data. It would activate when more channels contribute their data.

    How this is computed
    For videos with Browse-source rank-1 day, compare Browse impression
    decay rate to Suggested decay rate over the next 14 days. Cross-channel
    cohort baseline ideal. Agrees if Browse decay half-life > 1.5× Suggested.

    or a specific source.
    

    Source: YouTube official help docs.

  • Beliefinconclusive
    Channel-page-driven views come from highly engaged viewers.

    On this channel: 28.0 — the belief inconclusive here.

    n = 697, low confidence.

    How this is computed
    Compare AVD, retention pct, sub conversion, comment rate of Channel Page
    traffic vs Suggested traffic. Agrees if all four are higher for Channel Page.
    

    Source: Common assertion.

    On this channel: sample too thin to read — the belief inconclusive here.

    n = 21, high confidence.

    How this is computed
    For each engagement metric, Pearson correlation with sub conversion rate

    n = 13, low confidence.

    How this is computed
    For videos with comparable view counts, regress impression-rate-after-day-7

  • Beliefdisagrees
    High click-through-rate drives video success more than high retention.

    On this channel: 0.43×· ctr over retention· agrees ≥ 1.5× — the belief disagrees here.

    n = 21, high confidence.

    How this is computed
    Per video, scale CTR and retention to channel-relative units (each
    value's distance from the channel's median, divided by the channel's
    typical spread). Fit a linear regression of total views against both.
    If the magnitude of the CTR coefficient is at least 1.5× the retention
    coefficient, the data agrees that CTR dominates on this channel.
    

    Source: MrBeast school of creator advice; widely contested.

  • Beliefnot currently testable
    Neither click-rate nor retention alone matters; the product (or geometric mean) does.

    This belief depends on data not currently tracked: Awaiting Round 4 retention-curve-derived precision.. It would activate when Future round.

    How this is computed
    Define combined = sqrt(ctr_z × retention_z) per video. Regress total
    views on combined vs on CTR and retention separately. Agrees if combined-
    only regression has higher R² than either-alone.
    

    Source: Combined-quality folklore.

  • Beliefnot currently testable
    Channels publishing daily need pre-recorded inventory; those without it burn out.

    This belief depends on data not currently tracked: cross-channel cohort data. It would activate when more channels contribute their data.

    How this is computed
    Cross-channel only. Cadence break frequency over time for channels
    classified as `daily`. Cohort-level: agrees if daily-cadence channels
    with ≥30-video pre-publish queue have lower break rates than ad-hoc.

    For each video with ≥14 days tracked, what fraction of total lifetime
    views came from days 1–3? Channel median across qualifying videos.
    

    Source: VidIQ and TubeBuddy guides; widely repeated in creator literature.

    Source: End-screen optimization folklore.

  • Beliefnot currently testable
    End-screen impressions and clicks contribute 5–15% of traffic.

    This belief depends on data not currently tracked: Awaiting Round 4 retention/cards data ingestion.. It would activate when Future round.

Older channels become less dependent on algorithmic recommendations.not_currently_testablelow022
Distribution happens in two phases — test (low impressions, narrow audience) then scale.inconclusivelow022
Videos with average view percentage above 50% receive sustained impression delivery.inconclusivelow022
Browse / Homepage impressions are weighted toward existing subscribers.not_currently_testablelow022
Browse pickups are more durable than Suggested-driven impressions.not_currently_testablelow022
Cards contribute roughly 1% of traffic.not_currently_testablelow022
Channel-page-driven views come from highly engaged viewers.inconclusivelow022
As library grows, Channel Page share of views falls.inconclusivelow022
Comments-per-view tracks audience resonance better than likes-per-view.inconclusivehigh022
Comments are weighted more than likes by the algorithm.inconclusivelow022
High click-through-rate drives video success more than high retention.disagreeshigh42026-04-265
Neither click-rate nor retention alone matters; the product (or geometric mean) does.not_currently_testablelow022
Channels publishing daily need pre-recorded inventory; those without it burn out.not_currently_testablelow022
YouTube's algorithm tests a video primarily in its first 1–3 days, after which performance is largely set.inconclusivelow022
Once 30 days post-publish, a video's daily view rate stabilizes and varies little.inconclusivelow022
Editing title or thumbnail post-publish kills momentum.inconclusivelow022
Videos with high end-screen click-through have higher overall retention.not_currently_testablelow022
End-screen impressions and clicks contribute 5–15% of traffic.not_currently_testablelow022
Viewers from external sites have the highest engagement rates.inconclusivelow022
Days to first 100 subscribers is the slowest sub-acquisition leg.inconclusivelow022
Performance trajectory of the first 10 videos predicts month-12 channel state.not_currently_testablelow022
A video's lifetime trajectory is largely determined by its first 24–48 hour performance.inconclusivelow022
First video's day-30 performance correlates with month-3 channel trajectory.not_currently_testablelow022
Publishing video N consumes impressions that would otherwise have gone to video N−1, slowing N−1's trajectory.agreeshigh52026-04-247
The 0–15-second retention drop is the strongest single predictor of overall performance.not_currently_testablelow022
Hour-1 view rate predicts the video's lifetime performance.not_currently_testablelow022

Channels that post on a consistent cadence outperform those that don't.inconclusivelow022
Publishing too often cannibalizes per-video performance.agreeshigh52026-04-247
Long gaps between uploads cause the algorithm to deprioritize the channel.inconclusivelow022
Titles ending in ? outperform on click-through rate.not_currently_testablelow022
Once a channel has 30+ videos, key ratios (CTR, AVD, sub conversion) settle.inconclusivelow022
High retention drives video success more than high click-through-rate.agreeshigh42026-04-265
Videos with growing Search-source share over time become long-term assets.inconclusivelow022
