Check 17 / 21 LOW impact In the full checklist
Trust: '12,431 happy customers' under title
What this check is
A customer count under the product title is the fastest social proof on the page, but only if the number is defensible. The verifiable version of this check is a count you can stand behind or an equivalent trust signal such as review volume or a verified badge.
How to implement it
If you have the order history, state the count from real data and date it where it could look stale. If you do not, use the signals you do have: number of reviews, years trading, a review-platform badge, or press coverage.
How to verify it
Check the number against the store’s own reporting for the claimed period, and confirm the claim stays consistent with what the review widget and the footer say.
