Know your listing score before you hit publish
See a data-driven score out of 10 for any Amazon listing — yours or your competitors' — the instant you land on the page.
The problem
Optimizing listings shouldn't be guesswork
Most sellers have no objective read on how their listing stacks up — or how it compares to what's already winning in their category. MSC Extension turns that guesswork into a score.
