I’ve been developing a repeatable process for product research. The idea: use curated catalog speed to screen markets, then premium product depth to develop winners. Here’s how I narrow down a price niche before even looking at individual competitors.

Step 1 – Download the Best Sellers list

Use a tool like Helium 10 or Jungle Scout (I used Sorftime, but any tool with BS export works). Export the top 200–400 products from the category. Clean up the data: remove duplicate ASINs, convert text to numbers, fix image formatting.

Step 2 – Slice the market by price range

Set a price interval (e.g., $3 increments). Look at:

  • Sales share per interval – higher is better, but adjust for number of products.

  • Review count share – lower share relative to sales share often indicates newer, high-demand products.

  • Monopoly rate – if the top 3 products dominate a price range, be cautious.

Step 3 – Analyze sales trends over time

Use the tool’s trend view (if available) or download weekly data. Look for price ranges that consistently grow or have seasonal spikes. Avoid ranges where sales are declining.

Step 4 – Identify the “emotional center” of the market

After analyzing 3–4 charts in sequence, you’ll develop an intuition. In the watch box market, the $16–19 range clearly outperformed others in sales, review efficiency, and stability. Secondary ranges: $25–28 and $28–31.

Step 5 – Validate with higher/lower price brackets

Check $70–80 for premium opportunities (low competition, high margin). Check $7–10 for budget entry points (thin margin but high volume).

Key takeaways:

  • Don’t fixate on exact price points – market data has randomness. Focus on ranges.

  • The goal isn’t to find a “winning product” but to find the segment where winning is easiest.

  • Use the same process for any category. It takes <30 minutes once you’re familiar.
