Review Methodology

Emarter's rankings are built from data, not opinion or paid placement. Here's exactly what goes into every product page, category page, and best-sellers list on this site.

What we track

• Rating and review count — pulled directly from Amazon's own listing data.
• Best-seller rank (BSR) — Amazon's own real-time sales ranking within a category.
• Price history — we snapshot price on every data sync, so "best sellers" and "top picks" reflect sustained performance, not a single-day snapshot.

How rankings are built

Best-sellers lists are ordered primarily by review volume and rating, cross-checked against Amazon's own best-seller rank within that category. We do not accept payment from any brand, seller, or manufacturer to be included in or ranked higher on any list.

Update frequency

Product data (price, rating, stock status) is refreshed on a recurring sync. Every product page shows the date data was last checked.

What we don't do

• We don't rank sponsored or paid placements above organically top-performing products.
• We don't fabricate reviews, ratings, or testimonials.
• We don't display a price without noting when it was last verified.
