Week: 2026-03-16 → 2026-03-22
Growth Drivers
  • Surface concentration: Mixed surfaces
  • Momentum (72h): building (insufficient historical density for a stable median)
  • Market activity: 194 observations across 5 titles
Analyst Notes
  • GXI score: 57.7 (0–100).
  • Signals observed: 194.
  • Territory mix: US leads (43.8%). Top countries: US, IN, UN, CN.
  • youtube is currently capturing 65.0% of measured weekly discovery activity. Cycle state: Surface concentration. Median 72-hour velocity: 0.00. Interpretation confidence: Good confidence. Discovery is overly dependent on youtube, which increases fragility. Share-driven episode pickup is likely before broader platform conversion stabilizes.
  • Dominant signal types: 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 — "Cyrus Says" - Podcast (Country: IN)

  • Signals: 76
  • Primary discovery surface: yandex
  • Surface share: 63.2%
  • Cycle state: Surface concentration
  • Interpretation confidence: Good confidence (68/100)
  • Estimated 30-day attention value band: $2,373.63–$4,005.50
Surface mix:

yandex4863.2%
youtube2532.9%
seo_spam22.6%
web11.3%
Executive framing:
yandex is currently capturing 63.2% of measured weekly discovery activity. Cycle state: Surface concentration. Median 72-hour velocity: 0.00. Interpretation confidence: Good confidence. Discovery is overly dependent on yandex, 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: unknown
Recommended interventions:
  1. Protect the lead surface first: publish one native-format asset for yandex 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. Strengthen signal density before scaling spend aggressively.
