This site talks about sixteen products, and each of them has its own website. The easy way to get that wrong is to type a price on one page, change it on the product's site, and forget the first page. So we stopped typing them.
Each product's price, status and headline claims are written once, in a single facts file. Every page, the press boilerplate, the structured data search engines read and our llms.txt are filled from it when the site is built.
Every fact carries the page on the product's own site it was read from, the exact words that must still be there, and the words that would contradict us if they appeared. Today that is 135 checks across 40 pages of the products' own sites, and the build last found every one of them on 2 November 2026.
Each time the site is built, a script fetches those pages again. If a phrase has gone, or a product now says the opposite of what we say, the build fails and a person has to re-check the fact. On 1 October 2026 one release skipped this check; since 22 October it runs inside the build itself, and any exception has to be written down with a name, a date and a reason, and runs out within a week.
Each product's badge comes from the same file: six of our seven core products are fully open today. ServicePay is in early launch. Each card on the products page says which.
A second script reads every page before it is built and fails on anything we have decided we will not say. Each rule is written down with its reason, so a failure explains itself.
34 rules today, among them: a review called verified when nothing verifies it, a payout time we cannot promise, a launch date we have not set, an absolute privacy promise the connected products would contradict. When a product changes what it offers, the old claim is added here so it cannot creep back.
Any amount in pounds that the facts file does not hold fails the build. The only exceptions are the invented amounts in our labelled illustrations, and each one is listed by name in the rules.
Links to retired addresses fail the build. So do competitors' names: we describe what ours does and leave the comparison to you. And the physical things we sell are called touchpoints, everywhere, so one thing has one name.
Decoration crossing the words, a rotated label covering text, a colour that was never defined. Each fault we fix gets a check, so it is caught if it comes back. Our accessibility statement lists what is tested and what is still open.
This is the routine for this site, and the one we follow on the bespoke software we build for clients. Nothing about it is clever. It should never be skipped: the one time it was, on 1 October 2026, is why the checks now run inside the build itself.
We mark the last good version first, so going back is one step rather than a rebuild from memory.
Each guard is tested twice: once on the real site, and once on a copy with the old mistake put back in. A check that cannot fail is not a check.
Every page in the sitemap must load, have one main heading and the right canonical address, and carry structured data that parses. Every internal link must resolve directly, and made-up addresses must return "not found".
The previous version goes back automatically. Then a person finds the cause, fixes it, and writes down how it is stopped from happening again.
Each product keeps a changelog that records what changed, how it was checked and the measured result, so a claim made in one month can be checked in the next.
A release note says what was measured afterwards: which pages returned what, which checks passed, what is still open and who has to decide it. Illustrations on this site use invented businesses and figures, and each one says so.
