⚠️Most sellers don't fail at selling. They fail at choosing.
Enter an ASIN. Selltrix returns two independent readings: an Overall Entry Assessment — the official verdict on this product and listing (ENTER / WATCH / EARLY STAGE / AVOID / INSUFFICIENT DATA) — and Niche Openness, a separate score for how open the surrounding competitor set actually is.
The two readings routinely disagree — and that disagreement is the useful part. A cautious verdict on one listing sitting inside an open niche is a lead to source against, not a market to walk away from.

Bad products don't fail at launch — they fail at the research stage.
The problem is choosing without signal.

An Overall Entry Assessment (ENTER / WATCH / EARLY STAGE / AVOID / INSUFFICIENT DATA) alongside a Niche Openness score — plus risk breakdown, profit simulation, 1W/30D/90D momentum read, and an Action Plan.
Paste an ASIN and you get both readings back. The walkthrough below is scripted — illustrative values, not a real analysis.
Every dollar you protect is a dollar you can deploy on a better product.
Six listing-level signals. Each one is a proxy read on the ASIN you entered — its own demand, pricing, reviews and offers. None of them measures the market around it; that is a separate layer, below.
Niche Openness
Market level — not a 7th listing signalMeasured across the competitor set for the product term in the chosen marketplace — not on the analysed ASIN. This is the market a new listing would actually enter, and it carries its own confidence rating. It is reported next to the Overall Entry Assessment, never folded into it, which is why the two can disagree.

Rule-based verdict
FULL REPORT
Both readings + simulation
The honest answer — and why it's the right question to ask.
Five verdict states, two readings — and what it means when they disagree.
ENTER
Strong opportunity signal. Entry conditions are favorable under current market data.
WATCH
Moderate signals. Potential visible but not clean enough for confident entry. Monitor closely.
EARLY STAGE
Product shows promising signals but has too few reviews for a confident evaluation. Monitor as the market develops.
AVOID
Current signals do not support entry. Demand, competition, or financial conditions appear unfavorable.
INSUFFICIENT DATA
Not enough Keepa data for a full evaluation. Verify the ASIN is actively tracked in this marketplace, or try another marketplace where it sells.
Each analysis reports the verdict above alongside a Niche Openness score. Read them as a pair — the examples below are illustrative, not real analyses.
Overall Entry Assessment
ENTER
74 / 100
Niche Openness
EXCEPTIONAL
83 / 100
Both readings agree — the listing clears the bar and the market is unusually open. The strongest configuration this analysis can report.
Overall Entry Assessment
WATCH
66 / 100
Niche Openness
STRONG
72 / 100
They disagree. This listing is not clean enough to commit capital, but the door to the niche is still open — treat it as a lead to source a better product against.
Overall Entry Assessment
AVOID
38 / 100
Niche Openness
DIFFICULT
31 / 100
Both readings point the same way. The product does not justify capital and the competitor set is not offering an opening either.

Two readings that disagree — the listing's own signals are workable but not clean enough to commit capital, while the competitor set around it still scores STRONG. Read that as a lead on the niche, not an endorsement of this listing.
