Product Claims & Evidence Checks

Last updated September 14, 2026

Why a claim needs more than a label

A product page says "suitable for outdoor use". A shopper, or an AI assistant answering for one, needs to know more: does it hold up in rain, what test says so, and does that test apply to this model? A claim that answers those questions is easier to understand, compare and repeat accurately. A claim that does not is just an adjective.

Evidence checks are part of a product data audit. This page explains how they work.

How an evidence check works

Find the claims. Performance, suitability, compatibility and certification statements on the product page.
Attach sources. Spec sheets, test reports, certificates, manuals or manufacturer pages that you provide or that the page links.
Compare the claim with the source. Hasmord compares the wording of the claim with the source text and gives a first-pass status.
Confirm with a person. Automated matching is a starting point. Someone who knows the product confirms the status and decides what to change.

Status	Meaning
Consistent	The source supports the claim as written.
Partial	The source supports part of the claim, or a narrower version of it.
Conflict	The source says something different from the claim.
Insufficient	There is not enough in the source to judge the claim.

A worked example

Illustrative example. The product, fields and sources below are invented to show the format of a report. They are not a customer result.

Product: Example hiking jacket, model HJ-3. Claim on the page: "Fully waterproof for any weather."

Check	What was found
Source	A fabric test report linked from the page.
Does it match this model?	The report covers the fabric used in model HJ-2. The spec sheet says HJ-3 uses the same fabric, but the seams were changed.
Does it support the wording?	The report gives a water-resistance rating under a named test method. It says nothing about "any weather".
Status	Partial — the fabric result is supported; "fully" and "any weather" are not.

Before: "Fully waterproof for any weather."

After: "Waterproof fabric, rated [rating] under [test method] (fabric test report, linked). The same fabric is used on HJ-2 and HJ-3; HJ-3 seam taping has not been tested separately."

The rewrite is less dramatic and more useful: it says what was tested, which model it applies to, and what is still unknown.

What makes a source usable

Reachable: a page or document a reader can open, not a claim that a test exists.
Specific: it names the product, model or material the claim is about.
Dated: it says when the test or document was produced, so you can tell if it still applies.
Attributed: it is clear who produced it: the manufacturer, a test lab or a certification body.

What evidence checks do not do

They do not create evidence. If a source does not exist, the right change is to narrow or remove the claim.
They do not certify products or replace legal or regulatory review.
They do not guarantee how any AI assistant will describe or recommend a product.

Frequently asked questions

What is a product evidence check?

A check that connects a product claim to a source, confirms the source applies to that product and model, and marks whether the claim is consistent with it, partly supported, in conflict, or not yet supported.

Does Hasmord decide whether a claim is true?

Hasmord gives a first-pass status by comparing the claim with the source text. A person who knows the product confirms it and decides what to change.

What if I do not have a source for a claim?

Then the claim is unconfirmed. The usual options are to add a source, narrow the claim to what you can support, or remove it.

Is this a general knowledge base?

No. Evidence checks focus on the claims on your product pages and the sources behind them.
