llms.txt and GEO in 2026: How to Get Your Site Cited by AI Search
If you have a few hours, spend them making your pages easy for a machine to read and quote: server-render the content, keep one clear idea per section, add schema markup, and stop blocking AI crawlers in your robots file.

Generative Engine Optimization is the practice of getting your content surfaced and cited inside AI answers: ChatGPT, Gemini, Perplexity, Claude, and Google's AI Overviews. People also call it AI SEO or Answer Engine Optimization. The name matters less than the shift behind it.
