Negative Signal-Enhanced Recommendation Engine for Content Platforms

Published Feb 19, 2026

🔴 Problem Identified

Current recommendation systems primarily use positive signals (likes, views, saves) but ignore valuable negative signals like dismissals, skips, and low ratings. This leads to less precise recommendations and users being shown content they've already indicated they don't want, reducing engagement and user satisfaction.

💡 Proposed Solution

A specialized recommendation engine API that equally weights negative signals (dismissals, skips, low ratings) with positive ones to improve recommendation precision. The system would track and learn from what users actively reject, providing more accurate content filtering and discovery for streaming platforms, social media, and content apps.
