Why JSON-LD schema matters
Rich results eligibility
Google uses structured data to generate rich results — star ratings, FAQ dropdowns, article details. Missing required fields disqualifies your page entirely.
AI citation signals
AI systems like Google's AI Overviews and Perplexity use schema to understand authorship, dates, and content type. Clean schema improves your chances of being cited.
Programmatic enforcement
The best time to catch schema errors is at generation time, not after publishing. AutoBlogWriter enforces valid schema on every post automatically.
