Module 27: GEO: Generative Engine Optimisation for Wix | Lesson 304 of 571 | 25 min read

Just as robots.txt tells search engine crawlers what they can and cannot access, new file standards are emerging to communicate directly with AI systems. llms.txt provides a structured summary of your site for large language models. ai.txt provides guidance for AI agents. These are early-stage standards, but implementing them now gives your Wix site a significant advantage as adoption grows.

What is llms.txt?

llms.txt is a proposed standard (llmstxt.org) that provides a structured, markdown-formatted summary of your website specifically designed for AI systems. It lives at yourdomain.com/llms.txt and gives large language models a concise overview of who you are, what you do, what topics you cover, and where to find your most important content. Think of it as a cheat sheet for AI engines.

The format is simple: a markdown file with your site name, a brief description, and categorised links to your most important content. The goal is to reduce the need for AI engines to crawl and interpret your entire site, instead giving them a curated, authoritative summary they can reference instantly.

Content Selection: Only include your most important, highest-quality pages in llms.txt. This is a curated summary, not a sitemap. Link to 10-20 of your best pages that demonstrate your authority. Quality over quantity.

What is ai.txt?

ai.txt is a complementary file that provides instructions and preferences for AI agents interacting with your site. While llms.txt summarises your content, ai.txt communicates policies: what AI agents should know about your business, how they should represent your information, and any specific instructions about attribution or usage.

Hosting Static Files on Wix

Wix does not natively support hosting arbitrary text files at custom URLs. However, there are workarounds that achieve the same result. The most reliable approach is to add the content via Wix Custom Code in the site-wide head section as a meta tag alternative, or use the Wix Velo router to serve text content at the correct URL path.

How to add llms.txt functionality to your Wix site

Standard in Development: Both llms.txt and ai.txt are emerging standards that are not yet universally adopted. Implementing them now is a forward-looking investment. The content you create for these files is also useful for your schema markup and site architecture regardless.

robots.txt and AI Crawlers

Your existing robots.txt file also matters for GEO. AI crawlers like GPTBot (OpenAI), PerplexityBot, ClaudeBot (Anthropic) and Google-Extended respect robots.txt directives. If you want to be cited by AI engines, you must ensure your robots.txt is not blocking these crawlers. Check your Wix robots.txt and remove any blanket blocks on AI user agents.

Action Item: Check your Wix robots.txt at yourdomain.com/robots.txt. If you see lines blocking GPTBot, PerplexityBot or other AI crawlers, remove them. You want these crawlers to access your content so AI engines can cite you.
