Best schema markup generator — according to AI
We asked AI assistants 6 questions a real buyer would ask about schema markup generators — “what's the best?”, “what would you recommend for a small business?”, “what's a good affordable option?” — and counted which products the AI actually named. This is what the models recommend today (last checked August 24, 2026).

Methodology & honesty notes
Counts come from asking an AI model 6 standardized buyer questions and extracting the products it names — model knowledge, not live web search, and small samples move week to week. Treat position as directional, not a verdict. Not sponsored; no product can pay to appear here.
