FAQ

A few things to know.

What does BSR Spy help me find?

Designs and niches that are selling on Amazon: best sellers ranked by Best Sellers Rank, brand-new designs that have already made a sale, and the micro-niches inside a big trend.

Where does the research data come from?

From Keepa, a licensed provider that has tracked Amazon prices and sales ranks for years. BSR Spy does not scrape Amazon.

Can I cancel during my trial?

Yes. Cancel from the Billing page any time before the trial ends and you won’t be charged.

What does BSR mean?

Best Sellers Rank — Amazon’s own ranking of how well a product sells. #1 is the top seller, so a lower number sells more. A design only has a rank once it has made a sale.

How fresh are the numbers?

Top sellers are re-checked about every 4 hours and new listings are looked for every 30 minutes. Designs further down the rankings are refreshed less often, so treat their rank as a guide rather than a live number.

Why don’t I see designs published yesterday?

Amazon doesn’t show a rank until a design has sold, and in practice that appears about two to four days after it goes live. New Trends shows a design as soon as that rank exists.

Do you estimate how many sales a design makes?

Yes — each card shows an estimated number of sales per month, modelled from the design’s Best Sellers Rank, and lifted through the holiday season, when the same rank means more sales. Amazon doesn’t publish real sales figures, so it is an estimate; it is best read as “how big is this compared with that”.

What does it cover?

Novelty t-shirts on Amazon — men’s, women’s, girls’ and boys’ — the Merch on Demand style designs POD sellers compete with.

Will it stop me using trademarked designs?

We hide well-known brands, franchises and sports teams by default as a safety net. It isn’t legal advice, and no filter catches everything — always check before you publish.
