Keywords alone won't save your listing anymore.
Amazon's A9 algorithm used to rank products mainly by keyword relevance. COSMO changes the game entirely — it understands WHY customers search, not just WHAT they type.
We measure everything COSMO cares about.
Not a generic listing audit. Each category directly maps to what Amazon's COSMO algorithm evaluates when ranking your product.
What happens when Rufus reads your listing?
We simulate the questions Amazon's Rufus AI would receive about your product — then check if your listing can actually answer them. Questions Rufus can't answer from your listing = lost sales.
Keyword-optimized listing vs COSMO-ready listing.
COSMO Score is even more powerful with these tools.
Optimize your listing end to end — from keyword research to AI readiness.
