Overview

In early 2024 Helium 10 published a detailed case study showing how Amazon sellers can extract a rival’s most lucrative keywords and weave them into their own listings. The guide walks users through the platform’s Keyword Spy feature, demonstrating measurable gains in organic rank, conversion rate, and ad spend efficiency. Sellers who apply the method can capture more traffic without increasing their pay‑per‑click budgets.

Key Points

• Keyword Spy surfaces the competitor’s highest‑traffic terms — The analysis uncovered the ten keywords that generated the most sales for a best‑selling kitchen‑gadget product.
• Search volume spikes highlight priority keywords — One term, “silicone stretch lids,” recorded roughly 12 000 monthly searches, signaling strong buyer demand.
• Listing overhaul drives rapid rank improvement — After inserting three of the competitor’s top keywords, the test product jumped from position 27 to position 9 in just two weeks.
• Relevance boost lifts conversion — Adding the phrase “BPA‑free food storage” raised the product’s conversion rate by about 1.8 percentage points.
• Organic gains cut paid‑search costs — The seller trimmed weekly Amazon PPC spend by approximately $150 while keeping overall sales steady.
• Low‑competition keywords offer quick wins — Cerebro revealed that only three other sellers were ranking for “BPA‑free stretch lid,” making it an easy target for rapid ranking.

How Keyword Spy Works

1. Enter the rival’s ASIN — Paste the ASIN of a higher‑ranking competitor (e.g., B07XYZ1234) into the Keyword Spy interface. The tool returns a list of the competitor’s ranking keywords, each paired with an estimated monthly search volume and a relevance score. Example: “reusable silicone food bag” appears with an estimated 8 000 searches per month.
2. Filter for high‑impact opportunities — Apply built‑in filters to sort results by search volume, relevance, and competition level. Isolate keywords that rank within the competitor’s top 20 but are missing from your own listing.
