How the Validation Score Works

The validator weighs demand and competition equally and combines them into a single 0-100 score that maps to a GO, HOLD, or STOP verdict. Demand is read straight from monthly search volume. Competition is inverted from the average review count of the top 10 listings, because a low-review field means you can realistically outrank them.

Total Score = Demand Score + Competition Score

Demand Score: 10,000+ searches = 50; 5,000-9,999 = 35; 1,000-4,999 = 20; under 1,000 = 5.
Competition Score: top 10 avg reviews under 100 = 50; 100-499 = 35; 500-999 = 20; 1,000+ = 5.
Decision: total 70 or above = GO; 40-69 = HOLD; below 40 = STOP.

Real Example: Validating an 8,000-Search Keyword

You're researching a kitchen gadget with 8,000 monthly searches, 150 competing products, and a top-10 average of 250 reviews. Your selling price is $24.99 and your unit cost is $8.50. Here's the full walkthrough:

Step 1: Demand Score = 35 (8,000 searches lands in the 5,000-9,999 band)
Step 2: Competition Score = 35 (250 avg reviews lands in the 100-499 band)
Step 3: Total Score = 35 + 35 = 70
Step 4: Profit Margin = ($24.99 - $8.50) / $24.99 × 100% = 65.99%
Step 5: Decision = GO (total score 70 meets the GO threshold)

With a score of exactly 70 and a healthy 65.99% margin, this product sits right on the GO line. You'd want to confirm the 150 competing products aren't dominated by a single brand and that review velocity is achievable before placing your first purchase order.

Key Factors That Move the Score

  • Monthly Search Volume: High impact - jumps demand from 5 to 50 based on demand band alone
  • Top 10 Avg Reviews: High impact - inverted, so a thin-review field pushes competition score toward 50
  • Number of Competing Products: Medium impact - contextual signal of market saturation, not directly scored
  • Selling Price vs. Product Cost: Medium impact - drives the profit margin shown alongside the verdict

What This Validator Does Not Cover

The validator uses just two scoring signals so you can run it in under a minute. It does not model seasonality, trend velocity, brand dominance, review velocity you can realistically achieve, or PPC cost-to-rank. Profit margin here is gross of platform fees, shipping, and ads. Before ordering inventory, pair this with a full fee breakdown using our FBA ROI Calculator and a keyword trend check with our PPC Bid Calculator.

Understanding the GO / HOLD / STOP Framework

GO means demand and competition both favor entry - move to sourcing and a small test order. HOLD means one signal is strong but the other is weak; dig deeper before spending. STOP means both signals are unfavorable and you should redirect your budget to a better opportunity rather than fight a saturated or low-demand market.

Frequently Asked Questions About Product Validation

What does a score of exactly 70 mean - is it really a GO?
A 70 is a borderline GO. We treat 70 and above as GO because demand and competition are at least balanced, but you should treat it as a conditional yes. Confirm that the 150 competing products aren't locked up by one or two brands, check that you can realistically hit 50-100 reviews in 90 days, and verify the keyword trend isn't declining month-over-month before committing capital.
Why is the competition score inverted - fewer reviews gives more points?
Reviews are a proxy for how entrenched the top sellers are. If the top 10 average under 100 reviews, a new listing with a solid launch can realistically crack page one. If they average over 1,000 reviews, you'd need years and significant ad spend to compete, so the validator caps your competition score at 5. Lower review counts equal a more penetrable market, which is why they score higher.
My demand score is high but competition score is low - should I hold or stop?
A high-demand, high-competition niche (total in the 40-69 HOLD band) is often worth a differentiated entry, not a head-on attack. Look for an undersized variant, a bundle, or a listing-quality gap you can exploit. If your total is below 40 even with strong demand, the review moat is too deep - move on unless you have a 12-month ad budget and a clear differentiation angle.
Why doesn't the number of competing products affect the score directly?
Raw competitor count is noisy - 500 weak listings is very different from 500 entrenched brands. We use the top 10 average reviews instead because it directly reflects how hard it is to reach page one, where roughly 80% of sales happen. The competing products field stays in the form as context: if you see 1,500 competitors with a thin top 10, that's a fragmentation opportunity worth investigating.
