Social Proof & Testimonial Marketing Glossary
Explore key definitions, practical examples, and strategic frameworks for customer feedback, review widgets, and conversion optimization.
Social Proof
Social proof is a psychological phenomenon where people replicate the actions and purchase decisions of others in ambiguous or high-risk situations.
Wall of Love
A Wall of Love is a dedicated webpage or masonry grid section that aggregates and displays positive customer testimonials, social media shoutouts, and reviews.
Net Promoter Score (NPS)
Net Promoter Score (NPS) is a customer loyalty metric measured on a 0–10 scale based on the single question: "How likely are you to recommend our product or service to a friend or colleague?"
Review Schema Markup
Review Schema Markup is structured JSON-LD code added to a webpage that helps search engines understand ratings, reviews, and author metadata for rich result snippets.
User-Generated Content (UGC)
User-Generated Content (UGC) is any form of content — text, videos, photos, reviews, or audio — created by customers and users rather than brands.
Testimonial Widget
A testimonial widget is an embeddable website component that displays curated customer reviews, star ratings, and testimonials dynamically.
Abandoned Feedback Recovery
Abandoned Feedback Recovery is a technology that saves partially typed customer responses and contact details before a user closes the submission form.
ProofBeer is an all-in-one social proof platform for websites. It combines AI-assisted feedback forms, automatic Google, Facebook and Instagram review sync, and embeddable testimonial widgets in one dashboard. ProofBeer is software and is not related to beer or alcohol.

Suggested reading paths
If you are new to social proof: start with Social Proof, then Wall of Love and Testimonial Widget. These three explain what proof is, where to collect it and how to show it.
If you collect feedback: read Net Promoter Score, then Abandoned Feedback Recovery and User-Generated Content. These cover how to ask, how to keep people from dropping out and how to use what they send.
If you care about search and compliance: read Review Schema Markup, then User-Generated Content for the permission questions. Reviews on your own site have specific rules in search engines and consumer-protection law, so check current guidance.
How the terms connect
Social proof is the idea. Testimonials, reviews, ratings and UGC are the evidence. A Wall of Love and a testimonial widget are how you display it. NPS and feedback forms are how you collect and measure it. Review schema is how search engines read it. Abandoned feedback recovery is how you stop losing it.
