What problem does it solve? Product pages with good traffic but low conversion rates often lack trust signals. This Skill guides you through adding real-time social proof — recent purchase notifications, visitor counts, review badges, and low-stock indicators — using either dedicated apps or custom-built widgets for headless stores. ## Core Features & Use Cases - Platform App Setup: Step-by-step configuration of Fomo for Shopify, TrustPulse for WooCommerce, and ProveSource for BigCommerce, including targeting rules and A/B testing. - Custom Headless Implementation: TypeScript patterns for a social proof API endpoint with PII anonymization and a DOM-safe purchase notification toast widget that prevents XSS via textContent. - Low-Stock Urgency Indicators: Configure honest inventory-based urgency messaging using real stock counts on Shopify, WooCommerce, or custom builds. - Use Case: A Shopify store owner installs Fomo, configures it to show anonymized recent purchases only on product pages, and runs an A/B test to measure conversion lift before enabling it sitewide. ## Quick Start Ask the AI to set up a recent purchase notification widget on your Shopify product pages using Fomo, or to build a custom social proof API endpoint for a headless store.
