Every Amazon seller would love to see their product labeled as number one. Having a small orange #1 Best Seller badge on your product listings can mean more clicks, improved sales and a better reputation.
The badge appears in search results:
And also on product detail pages:
The Best Seller badge simply means that the product has a BSR of one. In other words, it is at the top of the Best Sellers chart for its main category.
While BSR in general is unlikely to influence sales, being the #1 Best Seller is a big deal and provides a lot of social proof that your product is the best. Having said that, getting to this position is way out of reach for the majority of sellers and unlikely to be a sensible goal in itself.
Note that this is a completely different badge from Amazon’s Choice.
