The Challenge
Jenna launched a baby swaddle blanket set in late 2023. Despite a strong product and good reviews, her BSR stalled around #42,000 — visible to almost no organic buyers. Listing optimizations from generic tools produced no measurable lift. She suspected her keyword strategy was targeting terms Amazon's AI search (Rufus) wasn't prioritizing, but had no way to confirm.
What They Did
1
KeySpy
Ran a competitor scan on the top 5 BSR-ranked competitors, discovered 3 high-volume intent clusters her listing was completely missing — specifically 'newborn swaddle sack' and 'hospital swaddle blanket set'.
2
COSMO Score
Checked COSMO Score — it returned 31/100, flagging critical gaps in semantic coverage for Rufus. Re-wrote title, bullet points and A+ copy following the COSMO recommendations, targeting intent rather than keyword density.
3
AI Listing
Used AI Listing to generate a Rufus-optimized backend keyword set and refresh the product description. Re-indexed all changes via Seller Central. COSMO Score jumped to 87/100 within 72 hours.
The Results
✓BSR improved from #42,400 to #1,680 over 87 days — a 96% rank improvement.
✓Organic sessions increased 4.2x with zero increase in ad spend.
✓Revenue grew 538% quarter-over-quarter.
✓Product now ranks page-1 for 8 high-volume keywords.
I'd tried every listing hack on YouTube — none moved the needle. COSMO Score showed me exactly what was missing. Once I fixed the intent gaps, the BSR improvement started within the first week.
