Methodology
How we score marketplaces
Every stamp on this site is a number we set deliberately, using the same five dimensions for all five marketplaces. This page explains how, so you can disagree with us precisely rather than vaguely.
The five dimensions
- Shipping Speed
- Typical door-to-door time for a standard order in a major market, not the best-case estimate.
- Trust & Reputation
- How predictable the buying experience is across sellers, and how consistent published policies are.
- Return / Refund Policy
- How easy it is to send an item back, who pays return shipping, and how long refunds take.
- Product Authenticity
- How confident a buyer can be that a branded item is the genuine article.
- Buyer Protection
- What happens when an order arrives broken, wrong, or never arrives at all.
How a score is set
Each dimension is scored out of ten. We start from the marketplace's published policy, then adjust for what actually happens: typical delivered timings in several major markets rather than best-case estimates, who pays return postage in practice, and how a dispute resolves when the seller stops replying.
The overall stamp is a weighted average of the five, with shipping speed, returns and buyer protection carrying slightly more weight than authenticity and reputation, because those are the three things a buyer feels directly when an order goes wrong.
We score for a global audience. Where a feature only exists in some countries, it cannot lift a score as if it were universal — that is why a fast domestic service in one market does not carry a platform's shipping score on its own.

Where Amazon sits, and why
Amazon scores highest overall on our five dimensions, and it is the platform we most often recommend for everyday orders. We say that plainly rather than hiding it behind a scoring model.
It is not the right answer everywhere, and our results reflect that: Alibaba wins bulk and wholesale sourcing, eBay wins used and collectible goods and leads on authenticity for high-value categories, and Temu and AliExpress win on price when you are not working to a deadline. A comparison that always produced the same winner would not be worth reading.
Who runs this site
checkingwithyou is an independent comparison publication. We are not owned by, operated by or editorially directed by any of the marketplaces we cover. Scores and verdicts are set by the editorial team and reviewed on a rolling basis as policies and delivery performance change.
Spotted something out of date, or scored in a way you think is wrong? That is useful to us. Corrections are made on the page and reflected in the review date.
