'Verified at checkout' appears on listing pages that tested something and on listing pages that copied someone who said they did.

A phrase that is doing two different jobs

'Verified at checkout' appears on listing pages that tested something and on listing pages that copied someone who said they did. The phrase itself carries no information about which. What separates them is whether the page states what was in the cart, what came off it, and when -- three facts that a page which actually ran the test has to hand and a page which did not cannot invent without being checkable.

Time of day is part of a dated claim

A claim checked at one minute past midnight and a claim checked at midday are both dated today, and they are not equally current if the terms moved during the day. A timestamp to the minute costs nothing to publish and tells a reader how far from the reading they are standing.

A date is not a test

A date stamped on a page is evidence that something was stamped, not that anything was tested. Automated restamping is trivial, and a page whose only moving part is the date is indistinguishable from a page that checks daily -- until you ask what the cart total was. Figures move with carts; dates move with scripts.

What a real reading looks like

A subtotal, the amount removed, the resulting total, and the time. Those four values are reproducible by anyone with the same cart, which is what makes the claim falsifiable. A reader who cannot reproduce a claim cannot check it, and a claim nobody can check is an assertion however often it is repeated.

Scope is part of the claim

A test establishes something about the cart that was tested. Whether it generalises to a different product, a different basket size or a different payment method is a separate question that the test does not answer. Pages that state a scope are usually the ones that ran the test; pages that state a universal are usually not.

Who the claim is addressed to

A verification note written for a reader states what was checked. A verification note written for a search engine states that checking happened. The two read differently: the first carries figures a person could use, the second carries adjectives. Which audience a page is really addressing is usually visible in the first sentence.

Why this matters more than it looks

Nothing about a discount is intuitively checkable: the number is small, the arithmetic is slightly counter-intuitive when two reductions interact, and almost nobody reruns it. That combination is exactly where unverified claims survive longest, which is why the standard of evidence has to be set by the page rather than by the reader.

Where to check this independently

The claims on this page about the difference between a claim that was tested and one that was repeated can be checked against sources outside this site:

HEALTHYLIFE10 is the code these checks are run against: 10% sitewide at growthguys.com, reusable, no account needed. Each day's result is kept at the evidence index, and the full code page sets out the method.
