How to configure robots.txt and llms.txt for AI crawlers
Modern search engines deploy specific AI bots — GPTBot, PerplexityBot, ClaudeBot, and Google-Extended. Misconfigured firewalls or robots.txt rules silently block these bots from citing your best content. Optymia audits your bot access, generates error-free robots.txt rules, and programmatically publishes an optimized /llms.txt file that guides AI engines directly to your priority assets.

Frequently asked
How to configure robots.txt and llms.txt for AI crawlers?+
In robots.txt, define explicit Allow rules for GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot, and Google-Extended. Then publish an /llms.txt file in your root domain following the standard Markdown format: include a brand overview, key product URLs, API documentation, and pricing links.
What is the purpose of an /llms.txt file?+
An /llms.txt file acts as a curated roadmap for LLMs and AI agents, serving clean, token-efficient Markdown that explains your site's structure, capabilities, and canonical resources without HTML clutter or JavaScript rendering overhead.
Will blocking GPTBot in robots.txt prevent my site from being cited in ChatGPT?+
Yes. If robots.txt blocks GPTBot or OAI-SearchBot, ChatGPT Search cannot retrieve your page in live browsing sessions, directly eliminating your brand from citation carousels.
Does Optymia auto-generate /llms.txt for websites?+
Yes. Optymia analyzes your sitemap and core entity hierarchy to auto-generate a valid /llms.txt file that you can download or publish via our Edge Proxy.
