Glossary

The terms Sourken uses, in plain words.

Sourken Score

Of the claims Sourken could check on a page, how well they hold up against official sources and research, out of 100. Claims with no evidence either way are counted separately, not scored.

Evidence label

The label beside a search result: strong, mixed or limited evidence, or not enough evidence yet. It describes the evidence behind a page's claims, not the business.

Strong evidence

Official sources back what the page claims.

Mixed evidence

Some of the page's claims hold up and some don't, or only in part.

Limited evidence

Most of the page's claims aren't backed by official sources.

Not enough evidence yet

The page has too few claims that can be checked to judge it.

Claim

Something a page states as fact, such as what a product does or what a law requires. Opinions and first-hand stories are labelled as such and never scored.

Official source

A government agency, standards body or other trusted publisher on Sourken's approved list, or published research.
A search result whose position was bought: an ad. Sourken marks it, beside the evidence behind what the advertiser's site claims.

Verified owner

Someone who has proved they control a website, by adding a file Sourken gives them. They can read the full reports on their own pages free.

Credit

What a new check or re-check uses. Holding credits also opens every saved full report.

90-day rule

Labels never disappear, but after 90 days they say they're aging, and checking the page again is one click.
