Most POD sellers lose money on designs that were never going to sell — then spend more promoting them. Tee Verdict tells you which is which up front.
Print the winners only
Validate sellability before you commit to a sample order or production run. Skip the weak ideas and stop funding dead inventory.
Spend ad budget where it pays
Put paid traffic behind designs with proven demand and room to break through — not saturated niches stacked with review moats.
Catch takedown risk early
Get an explicit warning when a design is a near-duplicate of an existing product or resembles licensed IP — before it gets pulled.
One number, fully shown
A sellability score you can actually defend
The 0–100 score is a weighted blend of six market signals — never a black box. Here's exactly what goes into it.
Similarity to winners
35%How closely your design tracks the niche's top sellers by market strength — the single biggest driver of the score.
Market demand
25%Review volume and best-seller-rank strength across the competing products in the niche.
Novelty gap
20%Rewards landing in the proven zone — familiar enough to sell, different enough to stand out — without copying.
Keyword strength
10%How well your title, tags, and niche cover the vocabulary that recurs across the market's best sellers.
Quality signal
10%The average star rating of the closest competing products, so a strong niche full of weak listings still reads as opportunity.
Saturation penalty
−30 ptsSubtracts for crowding, deep review moats, and duplicate slogans — the things that quietly bury new listings.
