Competition Analyzer
The 1,000-review wall is real. When the top ten results in a niche all sit above 1,000 reviews, a new seller with 14 reviews is invisible. Customers filter by reviews, and Amazon's algorithm treats a thin review count as a low-trust signal. This calculator reads how hard a niche is to break into from three numbers you can read off the search page in five minutes.
Enter how many of the top ten have more than 1,000 reviews, the average review count across the top ten, and how many you have. The tool scores it easy, medium, or hard.
The logic is blunt but useful. A niche where seven of ten incumbents clear 1,000 reviews is a wall — you will burn cash on ads just to be seen, and even then you lose the comparison. A niche where the top results average 200 reviews and two of them sit below 100 is soft. That's where a well-listed, Vine-seeded product can actually climb.
Here is the trap everyone falls for: a niche with almost no reviews looks "easy" in this tool, and that's exactly why it's usually a $0 market. If nobody has reviews, it's often because nobody is making sales worth reviewing. Low competition and zero demand look identical from the review count alone. Always pair this read with a BSR-to-sales check before you celebrate.
Your own review count nudges the score, but don't kid yourself — 50 reviews against 10,000-review incumbents changes nothing. The score tells you the truth about the climb, not about your odds of skipping it.
