For publishers & websites
You sell test materials. Who vouches for them?
Course creators, exam-prep websites, and publishers live off reputation. One wrong answer key in a paid product produces refund requests, public comments, and a support thread that never dies. Independent review is cheaper than any of those.
The economics of one bad item
A paying customer finds an answer key error in your practice test. They post it in the reviews. From that day, every prospective buyer who reads the reviews sees it, and your support team answers the same email indefinitely. The item cost nothing to get wrong and keeps costing forever.
A full audit of a 60-item product costs €90, finds those items before your customers do, and leaves you with a corrected version and a certificate. It is the cheapest insurance a content business can buy.
The badge on your product page
Audited material can carry the Quality-checked by EnglishCorrection badge. The badge is an inline snippet that links to a verification page on our domain showing what was reviewed, when, by whom, and whether the certificate is still valid. It cannot be faked by copying an image, because its value is the page it resolves to.
If material is modified after review, the certificate is revoked and the verification page says so — which is exactly why the badge is worth something. See a live verification page.
