Week: 2026-03-30 → 2026-04-05
Growth Drivers
  • Surface concentration: Mixed surfaces
  • Momentum (72h): median 14.0 attention observations per title
  • Market activity: 86 observations across 5 titles
Analyst Notes
  • GXI score: 46.2 (0–100).
  • Signals observed: 86.
  • Territory mix: US leads (75.6%). Top countries: US, GB.
  • youtube is currently capturing 87.2% of measured weekly discovery activity. Cycle state: Acceleration. Median 72-hour velocity: 14.00. Interpretation confidence: High confidence. Discovery is overly dependent on youtube, which increases fragility. Share-driven episode pickup is likely before broader platform conversion stabilizes.
  • Dominant signal types: mirror, clip_chain, unknown.

What this week indicates

This weekly build is designed to show not just where attention exists, but where next-stage demand is most likely to form, which surfaces are actually carrying the title, and what intervention windows matter before momentum diffuses or gets captured inefficiently.

Top 5 Expansion Titles

Title-level intelligence on where discovery is concentrating, what likely happens next, and which interventions can improve conversion efficiency.

#1 — Joe Rogan Experience - podcast (Country: US)

  • Signals: 26
  • Primary discovery surface: youtube
  • Surface share: 92.3%
  • Cycle state: Acceleration
  • Interpretation confidence: Good confidence (73/100)
  • Estimated 30-day attention value band: $1,096.24–$1,849.91
Surface mix:
SurfaceSignalsShare
youtube2492.3%
dailymotion13.8%
apple_podcasts13.8%
Executive framing:
youtube is currently capturing 92.3% of measured weekly discovery activity. Cycle state: Acceleration. Median 72-hour velocity: 14.00. Interpretation confidence: Good confidence. Discovery is overly dependent on youtube, which increases fragility. Share-driven episode pickup is likely before broader platform conversion stabilizes.
Why this matters:
For podcasts, distribution is usually uneven early. A strong lead surface often reveals which topic angle is actually carrying listener acquisition.
Next likely outcome:
Share-driven episode pickup is likely before broader platform conversion stabilizes.
Signal quality notes:
  • Dominant signal types: mirror
Recommended interventions:
  1. Protect the lead surface first: publish one native-format asset for youtube within 24–48 hours.
  2. Route paid and organic traffic into one owned conversion path instead of splitting attention across weak destinations.
  3. Do not over-diversify yet. Concentrate around the current lead surface while discovery is still coherent.
  4. Use topic-led clip packaging and one clear listen CTA to convert conversation into episode starts.
  5. Treat this as an active intervention window, not a reporting window. Move in hours, not next week.

#2 — "Stalked - 2026 Podcast" - Hannah Mossman Moore and Carole Cadwalladr (Country: GB)

  • Signals: 14
  • Primary discovery surface: youtube
  • Surface share: 100.0%
  • Cycle state: Initial detection
  • Interpretation confidence: Measured confidence (64/100)

#4 — "The American Cinematheque Podcast" (Country: US)

  • Signals: 18
  • Primary discovery surface: youtube
  • Surface share: 50.0%
  • Cycle state: Acceleration
  • Interpretation confidence: Good confidence (76/100)

youtube950.0%
instagram527.8%
tiktok422.2%
Executive framing:
youtube is currently capturing 50.0% of measured weekly discovery activity. Cycle state: Acceleration. Median 72-hour velocity: 14.00. Interpretation confidence: Good confidence. youtube is leading decisively, which is useful for focus but still needs conversion protection. Share-driven episode pickup is likely before broader platform conversion stabilizes.
Why this matters:
For podcasts, distribution is usually uneven early. A strong lead surface often reveals which topic angle is actually carrying listener acquisition.
