.csv only · Keepa Product Viewer exportResearch competitors before you spend on Amazon PPC
Every product targeting campaign is a bet that shoppers viewing a competitor's listing will prefer yours. Most sellers place that bet blind — they pick ASINs that look beatable and hope. The data to make it a calculated decision already exists in Keepa: sales rank history, rating and review trajectories, and price movements tell you exactly which competitors are strong, which are slipping, and which are vulnerable to a well-placed ad.
This comparator turns a Keepa Product Viewer export into a side-by-side battlefield view. Instead of opening ten browser tabs and eyeballing charts one at a time, you upload one CSV and compare every ASIN's BSR trend, rating, review count, and pricing in a single dashboard — then pick your targets with evidence.
How It Works
- 1
Export from Keepa Product Viewer
In Keepa, add the ASINs you want to analyze to the Product Viewer and export the list as a CSV. Any set works — competitors in your niche, your own catalog, or a mix of both.
- 2
Upload the CSV
Drop the file into the tool. Parsing happens entirely in your browser — the file is never uploaded to a server.
- 3
Select the ASINs to compare
Choose which products to show and switch between 2-column and 3-column card layouts. Each card shows current and historical sales rank, subcategory ranks, ratings, and reviews.
- 4
Pick your targets
Use the side-by-side view to spot weak competitors — declining BSR, low ratings, thin review counts — and feed those ASINs into your Sponsored Products product targeting campaigns.
When To Use This Tool
Product targeting campaigns
Find competitor ASINs with worse ratings, fewer reviews, or higher prices than yours — the listings most likely to lose a shopper to your ad.
Spot weakening competitors
A slipping BSR trend signals a competitor losing momentum. Their detail page traffic is still there — a perfect moment to place ads on it.
Pre-launch niche research
Before launching a product, compare the incumbents' sales ranks and review moats to gauge how hard the niche is to crack and where the gaps are.
Benchmark your own catalog
Include your own ASINs in the export to see exactly how your rank, rating, and price stack up against the products you compete with daily.
Frequently Asked Questions
You need Keepa access to create the Product Viewer export — the CSV this tool reads comes from Keepa's Product Viewer feature. The comparator itself is completely free. If you already use Keepa for product research, there's no additional cost.
Best Sellers Rank reflects recent sales velocity relative to other products in the category — lower is better. A single BSR snapshot can be misleading because ranks swing daily, which is why this tool shows historical rank alongside current rank: a competitor at BSR 5,000 and climbing is a very different target than one at 5,000 and falling.
Look for competitors where you win on at least two of the big three: rating, review count, and price. Shoppers on a detail page comparing options will click to the better offer. Targeting a stronger listing than yours usually just donates clicks — target listings you beat on the merits.
No. The CSV is parsed locally in your browser and nothing is sent to a server. You can verify this in your browser's network tab — no requests fire when you upload.
