Quizproof

How change control works

Quizproof only recommends product data you have approved. When something changes in your catalog that could change a recommendation, the product is taken out of results until you review the change on the Changes page. Nothing new enters results without your approval; changes that can only remove a product (archived, deleted, unpublished, out of stock) take effect at once.

How quickly changes are caught (measured)#

Shopify sends a notification for most product edits; for the others Quizproof re-checks your catalog on a schedule. We measure how long a change takes to appear on Changes and to leave your quizzes on a test store (95th percentile, rounded up: 19 changes in 20 are faster):

Changes are never "instant": between your edit and its detection, shoppers may still see the previous data. If products cannot be verified for 24 hours they are hidden until they are.

Menu paths such as Settings › Privacy are inside Quizproof: in your Shopify admin, open Apps › Quizproof. Where an article means Shopify's own settings, it says so.
