An SEO checklist isn't enough anymore.
A listing can tick every box on an Amazon SEO checklist and still lose the sale, because shoppers now ask Alexa for Shopping and Amazon's CoSMo algorithm decides which products fit the question. A good listing quality score has to measure that: whether your listing answers what shoppers ask, and whether Amazon understands who it's for.
Questions, answered.

Is this Amazon listing quality checker free?
Yes. Create a free Cosmy account, no credit card needed. The Free plan includes 5 credits a month, and one analysis uses one credit.
What does the listing quality score measure?
Three things: whether your listing can answer the questions Alexa for Shopping asks (Alexa for Shopping score), how well it covers the 15 dimensions of Amazon's CoSMo algorithm (CoSMo score), and how well it says what your reviewers say (Shopper Voice). The product score is the average of the first two.
Does it show what to fix?
Yes. Every gap comes with what's missing and why, and Cosmy can rewrite the listing to fix it.
Can I check a listing again after changes?
Yes. Run a new analysis any time, or track the product and Cosmy re-scores it twice a month.
Which marketplaces are supported?
8 Amazon marketplaces: Canada, France, Germany, India, Italy, Spain, the UK and the US.
