Never a factor
Affiliate commission rates, sponsorships, brand relationships, and advertising spend play no role in scoring. The score model has no field for them.
Methodology
How every ranking is built.
Every product position on this site is earned through data — aggregate rating, review depth and recency, price-to-value within its category, and availability. No brand can pay to rank higher, and affiliate relationships never enter the scoring model.
The signals
What the score is made of.
Rankings start from the live product catalog and combine several independent signals into a single comparable score per category. The weighting is category-aware: review depth matters more in crowded categories like earbuds, while recency matters more in fast-moving ones like laptops.
Aggregate customer rating and total review volume — a 4.6 across 12,000 reviews outranks a 5.0 across 12.
Review recency — products whose recent reviews trend below their lifetime average are penalized.
Price integrity — list prices are checked against 30-day street prices so inflated 'discounts' don't earn deal placement.
Availability and purchase velocity — out-of-stock or declining products fall out of shelves automatically.
What never counts
Independence, enforced by design.
The ranking pipeline is fully automated and has no input field for commercial relationships — there is structurally no way for a merchant, brand, or affiliate program to influence a score.
Always disclosed
Outbound product links are affiliate links and are labeled as such. See the Affiliate Disclosure page for exactly how we earn and why it cannot affect rankings.
Common questions
Ranking FAQ
How often are rankings refreshed?
The catalog is refreshed continuously and shelves are rebuilt daily. A product's position can change any day its underlying data changes — new reviews, a price move, or an availability change.
Why do you show Amazon products only?
Amazon's review corpus is the largest consistent source of genuine post-purchase feedback, which is what the scoring model is built on. Where specs match, the ranking is product-first — the merchant is interchangeable.
Can a brand pay to be listed or ranked higher?
No. There are no paid placements anywhere on the site, and no mechanism for commercial input into the ranking pipeline.
I found a ranking that looks wrong — what do I do?
Use the Contact page and include the product and category. Data corrections are reviewed and re-scored against the live catalog.
