The AI Agent era is here, and websites need to start 'understanding AI'—Vercel is diving into SEO now!! In the future, doing Agent SEO means figuring out how to make AI Agents like Claude, GPT, and Grok understand, access, and interact with your website. What is-agentic does is test whether Agents get lost when visiting your site. It can run 100+ Agent readability checks, simulate how Agents browse pages, and directly generate fix suggestions. It even provides a CLI tool so Agents can optimize things themselves. In the future, many users won’t open websites to search—they’ll just tell AI: 'Help me buy this' or 'Help me complete this task.' If your product can’t be understood by Agents, you’re essentially missing out on a new traffic channel. SEO used to be about fighting for search rankings, but the next competition might be about fighting for AI Agents’ understanding.
