Who pays, and who does not

We are paid a commission by some of the sellers listed in this index. With most of them we have no arrangement of any kind, and no money has ever changed hands in either direction. Where there is an arrangement it is always the same one: a share of what a referred buyer spends, agreed with the seller. There is no listing fee here, so there is none to waive.

A seller cannot buy a row. Nothing was added to this index because a company offered to pay for it, and nothing would be. What gets a seller listed is on the editorial policy page, and it is a test about what the company publishes about price, not about what it pays.

Where the money shows

Payment moves one thing, and it is worth naming plainly rather than leaving to be noticed: position. Sellers that pay us are grouped at the head of a board as a labeled block, and the board’s own stated order then runs inside that block and again inside the larger block below it. A commercial arrangement can therefore decide which card you read first. Every board says so above itself, in the same words, whether or not you arrived from this page.

The score is worked out independently. The order is not always. Both halves of that are true at once, and a site that admits only the first half is describing something other than itself.

What payment does not move

• Not a figure. A price here is whatever the seller’s own page said on the day it was read, transcribed as it stood. A commission does not re-read a page and cannot round one.
• Not a qualifier. A from-price stays a from-price, a first-period rate stays a first-period rate, and a prepay total is never quietly divided down into a monthly number to make a paying seller sit better against one that publishes a standing rate. A number without the words attached to it is not a price, which is the whole argument of this site — and money is the pressure most likely to bend it, so the rule is written down here rather than left to good intentions.
• Not a reading date. Each figure carries the day this site read it, and that date is not refreshed because a seller became a partner.
• Not a score. The price disclosure score asks the same short list of questions of every seller’s pages, and not one of them asks whether that company pays us. A build check re-runs every board and every score with the payment flag switched on for every seller at once and requires the results to come back identical.
• Not a sentence. No seller reads a write-up before it goes up, none can have a conclusion pulled, and a fact about a paying seller is not written more warmly than the same fact about one we earn nothing from.

The sellers we earn nothing from

Most of this index is made of them, and they are not filler. They appear on the same boards under the same headings, with the same button and the same reading date, and their figures are read off their own pages the same way a partner’s are. None of them is hidden, none is softened, and none is being kept around to make the rest look better. If the seller you want is one of them, click it with our blessing; we will simply not be paid for it.

Why there is no tally on this page

This page used to carry a running count: how many sellers were in the index, how many paid, how many did not, and then the name of every company in the second group. It has been taken down, and the reason is the one the rest of the site is built on. A figure is only worth reading with its date and its qualifier beside it, and a count of who pays us is true for the length of one build. The roster moves, an arrangement starts or ends, and a screenshot of this page goes on asserting last week’s arithmetic to whoever is looking at it.

So the shape is published here instead of the arithmetic, because the shape is the part that holds: some of the sellers listed pay us, most of them do not, and payment groups a card higher and moves nothing else. The counts themselves are still worked out from the index on every build. A build check recomputes them in a separate process and then reads this page to confirm that not one of them has been printed back onto it.

How a link behaves

Every seller button on this site, paid or not, goes to a /go/ address on this domain first and on to the seller from there. For a seller that pays us, that hop carries the identifiers a commission is traced by, so a payment can be tied back to the page and the position the click came from. For a seller that does not, it carries none of that, because there is no relationship to attribute anything to. A paying seller’s button has a short “Partner” label beside the provider name. A visible commission notice accompanies paid links. The row itself tells you which kind you are looking at before you click, which is why the sentence does not have to be repeated beside every unpaid seller in the index.

Crawlers are told not to follow /go/. Paid seller links are marked as sponsored in the markup; unpaid seller links are not.

Pages that sell nothing

Some pages here carry no seller link at all, and that is what makes the claims on the pages that do carry one checkable. Every page listed below carries zero outbound seller links, asserted on each build by walking that page's real module import graph and then re-reading its rendered HTML, rather than by trusting this sentence.
