Observed, not inferred
A number appears only when it is actually visible. Nothing is back-filled from an assumption, and a missing field is never counted as zero.
METHODOLOGY · PUBLIC DATA
How Clip Score and Demand Index are calculated
ClipAlytics turns public creator-marketplace observations into seller-focused direction signals. The scores help creators decide what deserves more research; they do not estimate private revenue, guarantee sales or identify individual buyers.

01 · DATA SCOPE
What the market numbers describe
Market reports describe what anyone can see without an account: how many listings compete in a category, how their prices cluster, and how much the rankings move week to week. They do not describe what any creator earned. Where a figure is not publicly available, the report leaves it blank instead of filling it with a guess.
Coverage varies
Marketplaces publish different things, so some reports carry price and engagement while others carry supply and cadence only. Each report shows what it is based on.
Your own numbers come from you
Catalogue and sales figures are added by the creator — a forwarded receipt, a CSV, or a connection you authorize and can revoke.
02 · CLIP SCORE
A 0–100 seller-opportunity score
Attention is a robust z-score of log-scaled social mentions, authors, and engagement versus the niche's own 30-to-90-day median. Supply growth is the same treatment of day-over-day listing change. Saturation headroom scales the gap so a crowded category needs a larger attention lead to score equally. The opportunity score is:
Opportunity = (AttentionZ − SupplyGrowthZ) × (1 + headroom)
Clip Score = clamp(50 + Opportunity × 12, 0, 100)
Headroom is (100 − saturation) / 100. Bluesky and X start at 60/40 and are renormalized when a source is off. High attention with slower supply growth pushes the score up. Rapid supply growth without matching demand pushes it down.
03 · DEMAND INDEX
Demand relative to each niche's own baseline
The Demand Index is the Clip Score pulled toward 50 until 30 days of history accumulate. Daily social attention uses log-scaled mentions (50%), unique authors (40%) and engagement gained (10%), with a per-author daily mention cap. Each input becomes a robust z-score: (value − median) / (1.4826 × MAD). Bluesky and X begin at 60/40 weights and are renormalized when a source is disabled.
Robust baseline
Each input becomes a robust z-score using the historical median and median absolute deviation, reducing the effect of one viral spike.
Supply headroom
Attention relative to supply growth is adjusted by saturation headroom, so a crowded category needs stronger demand to score equally.
Warm-up bound
New series are pulled toward the neutral score of 50 until 30 days of history accumulate. Coverage records the enabled sources and confidence.
04 · DEFINITIONS
How to read the public seller metrics
- Active supply
- Listings publicly visible as active in a niche on the snapshot date. Cross-platform totals can include the same creative work listed on more than one marketplace.
- Tracked market price
- The median public listing price where prices are visible. Where they are not, the report shows a labelled estimate based on the price bands it can see. It is not a completed-sale price.
- Seven-day turnover
- The share of tracked positions or listings that changed across the seven-day comparison window. It measures rank movement, not purchases.
- Saturation
- A 0–100 supply-and-stickiness signal. Higher values mean deeper public supply and harder-to-move rankings; lower values indicate more headroom.
- Coverage
- How complete a report is for the day shown. Lower coverage means fewer fields were available; the report says so rather than filling the gap.
- Clip Score
- A 0–100 seller-opportunity score. Attention and supply-growth are converted to robust z-scores against each niche's own 30-to-90-day baseline, then Opportunity = (AttentionZ − SupplyGrowthZ) × (1 + saturation headroom) is mapped to 0–100 as clamp(50 + Opportunity × 12, 0, 100).
- Demand Index
- The same opportunity score, pulled toward a neutral 50 until 30 days of history accumulate. Daily attention is log-scaled mentions (50%), unique authors (40%), and engagement gained (10%), with per-author mention caps so one account cannot flood the series.
05 · CITATION & LIMITS
Cite the page, source scope and date
A defensible citation names the metric, niche, visible snapshot date and report URL. Say “public listings” rather than “sales,” and “tracked market price” rather than “earnings.” Coverage varies by source and geography, and public pages cannot reveal private purchase volume, refunds or subscriber conversion.
