Reverse ASIN is a keyword research tool that reveals the search terms driving traffic to a product on Amazon. Simply enter an ASIN, and it captures all keywords that brought that product into the top 3 pages of search results over the past 30 days. The tool provides detailed metrics to help you identify high-converting, relevant keywords and filter out irrelevant or low-performing ones.
How to Use
Example using ASIN B09PCSR9SX:
Enter the ASIN and click [Search] to retrieve 14,933 search-driven traffic keywords that ranked within Amazon's top 3 search results pages over the last 30 days, including their traffic distribution percentages.
1. View Variation-Specific Keywords
For products with multiple variations (e.g., colors/sizes), click individual variations to analyze their unique keyword traffic. To consolidate keywords across all variations: Click [Get keywords of all variations] to access the Reverse Multiple ASINs feature. Results show merged and deduplicated keywords.
2. ASIN Insights
View sales trends, core keyword performance, and market seasonality data to assess product lifecycle stages and identify peak/off seasons.
3. Traffic Breakdown
Some keywords drive both organic and sponsored traffic. In such cases, organic + sponsored % may exceed 100%. For example, this ASIN has 28.94% organic and 90.54% sponsored traffic – totaling 119.48%, meaning 19.48% of ads were run for keywords already ranking organically in the top 3 pages to strengthen positions. Click the bar chart or use filters to see which keywords have active ad campaigns (e.g., SP, Video, HR).
4. Historical Trends
For seasonal or newly launched products, analyzing historical keyword data helps refine your strategy.
For example, paid traffic of the portable neck fan surges in the peak sales season, indicating strategic ad budget increases during high-demand periods.
Applications
Use Case 1: Analyze Competitor Traffic
1. Build Your Keyword List
Use Reverse ASIN to identify accurate high-traffic keywords. Collect several competing ASINs and run them through batch mode via Reverse Multiple ASINs.
Analyze ad placement types (SP, Video, HR) to uncover which keywords competitors are bidding on.
3. Understand Keyword Impression Share
Each keyword shows its share of total impressions. For instance, “fathers day gifts” accounts for 14.68% of total impressions for this ASIN—making it a core term.
Use Case 2: Analyze Your Own Product
1. Track Keyword Rankings
Monitor your organic and ad rankings for key terms. See daily rank changes and verify if listing updates are working.
2. Fill Ad Keyword Gaps
If keywords with decent traffic aren’t yet in your ad campaigns, or your ad rank is low, consider increasing bids to gain exposure.
3. Check Keyword Relevance
Run bulk checks on indexed keywords for your product. If you find irrelevant terms indexed, review your listing copy. You can also visually inspect the top 10 listings for each keyword to determine whether they’re relevant to your product.
Export results to Excel and cross-reference them with your ad reports. This helps spot irrelevant keywords that are draining ad budget—so you can set negative keywords in time.
