Amazon research,
on the page.
The MerchRadar extension puts BSR, exact date added, sales signals, reviews and opportunity labels directly on Amazon search results and product pages — while you scroll. Free. Public data only. No seller account needed.
Live on the search page: NEW BREAKOUT labels, BSR grades, actual vs. estimated sales, blurred sponsored ad — all real extension output.
BSR on every shirt, rated
Best Sellers Rank pulled onto every search card and product page, graded HOT / STRONG / ACTIVE / SLOW so you read demand at a glance.
Exact date added
Not just the month — the exact day the shirt went live on Amazon, plus its age. New shirt + real BSR = it's selling right now.
Real sales, or honest estimates
When Amazon publishes "bought in past month" you get the actual number with an AMAZON tag. When it doesn't, you get a BSR-based monthly estimate clearly marked EST. You always know which one you're looking at.
3-level opportunity labels
NEW BREAKOUT (new + BSR ≤50k), NEW & SELLING (new, any BSR) and SELLING (recent + BSR ≤150k). You choose what "new" means: 15, 30, 90 days or this year.
Sponsored results, neutralized
Ads can't be removed from Amazon — so MerchRadar blurs them and stamps them SPONSORED · AD. Organic research signal only. One click on 👁 SHOW reveals any ad you actually want to see.
