AgentGrade is a website scan tool that grades how visible a page is to AI systems such as ChatGPT, Claude, and Perplexity. You paste a URL and receive an A-F report card scored from 0 to 100 across categories that measure whether the page can be crawled, understood, answered from, and cited by AI agents.
The product is designed for the AI-first web, not for traditional blue-link SEO alone. Its methodology page says each scan uses a transparent checklist with weighted pass, warn, and fail signals, and the overall grade is adjusted by page type so a homepage, article, landing page, or API/app page is judged in context.
