Verified reviews and SEO
Verified reviews come from third-party platforms (Trustpilot, Avis Vérifiés, Google Reviews) that authenticate a purchase before publication. Their Schema.org integration and overall volume influence E-E-A-T signals and CTR in the SERP.
In practice
Google assigns more weight to reviews from independent third-party sources than to self-hosted reviews, as they are harder to manipulate. Connecting a Trustpilot widget with proper markup, then surfacing the global rating in the homepage metadata, can trigger star ratings in sitelinks or brand rich snippets — a CTR gain in the range of 10 to 20%.
