## Summary

Amazon Marketplace is testing a new AI system to evaluate the quality of A+ Content—rich media widgets on product detail pages—by assessing the entire page as customers see it. The system combines a vision-language model (VLM) with optical character recognition (OCR) to score four dimensions: Visual Storytelling, Feature Presentation, A+ Layout, and Conversion Optimization. It also uses a CatBoost classifier trained on expert annotations from 5,478 product pages across 10 categories to refine scores and provide actionable feedback via SHapley Additive exPlanations (SHAP). The approach improves accuracy and explainability compared to baseline methods, with a 1.4-point average quality score increase after revisions based on recommendations.

The system renders each page as a single snapshot, allowing the VLM to assess how individual assets interact rather than evaluating them in isolation. OCR signals—like Text Density, Character Density, and Spacing—complement the VLM’s holistic judgment, addressing fine-grained readability issues. SHAP identifies which features drive low-quality decisions, and an LLM translates those insights into specific improvement suggestions. Deployed on Amazon SageMaker AI, the pipeline supports scalable rendering, inference, and monitoring, with plans to explore lighter VLM backbones for global catalogs.

## Key points

- Amazon’s SageMaker AI system scores A+ Content quality by rendering pages as snapshots and using a VLM with OCR signals
- CatBoost classifier trained on 5,478 expert-annotated pages improves accuracy over baseline scoring methods
- SHAP explains decisions and an LLM generates actionable improvement recommendations for sellers

## Why it matters

This approach helps Amazon Marketplace sellers create more effective A+ Content by identifying cohesive, customer-focused layouts and readable text, potentially boosting conversions and revenue.
