Methodology

How we rank

How prices work here

Every offer you see was checked by us against the store's own product page, and the date of that check is printed next to the price. We never estimate a price, carry one over from memory, or copy one from another comparison site. If we could not verify a store's current price, that store simply does not appear for that product.

Prices change constantly, so treat the store page as authoritative. Listed prices exclude shipping and taxes, which vary by state and cart.

Where the shopper ratings come from

A star rating on this site is never ours. It is the rating a store publishes on its own product page, copied down with the store's name, a link to the page it came from, the number of ratings it was based on, and the date we read it. If a store shows no rating, no rating appears for that store here. We do not run reviews, we do not collect ratings from readers, and we do not invent either.

When two or more stores publish a rating for the same product, the single number at the top of the block is a count-weighted average of those store scores on a five point scale. Weighted by count means a score built on ten thousand ratings pulls harder than one built on twelve, which is the honest way to combine them. It is arithmetic on published numbers and nothing more. The per-store rows underneath always show the original figures, so you can ignore our average and read the sources directly.

Two things worth knowing about store ratings in general. They mix reviews of different variants, colours and generations of the same product more often than you would like, and a product with a handful of ratings tells you very little either way. We print the count next to every score for exactly that reason.

We do not put these ratings into the structured data that search engines read. Google's guidelines are that ratings shown as rich results should be collected by the site publishing them, and that ratings gathered by other sites should not be aggregated into a rich result. Showing you the stores' numbers with their names attached is useful. Passing them off to a search engine as our own would not be, so we do not, even though the stars would look good in the results page.

How products are picked

We cover the products people actually search for and buy in each category: the current models from established brands, plus budget options that hold up. We research specifications from the manufacturer, read widely, and write the pros, cons and verdict ourselves in plain language.

What our verdicts are not

We do not run a physical test lab, and we do not pretend to. Verdicts are careful research summaries, not lab measurements. We never publish a star rating or a review count of our own invention: the only ratings here are the stores' own, attributed and dated, as described above. And we make no medical claims. A white noise machine masks background noise, it does not cure anything, and you will never read otherwise here.

Ranking, concretely

Within a product page, offers sort by price, cheapest first, always. Category pages sort by best price, also cheapest first, and shopper ratings are shown as a column rather than used to reorder anything. Within a buying guide, the order is editorial: we name the award each pick earned and explain the reasoning right there. Stores cannot pay for placement, and no brand sees our content before you do.
