LLM SEO: how to rank inside ChatGPT, Perplexity, and Google AI Overviews

By Fahid Ali Published: July 2026 11 min Read

SEO is changing. With ChatGPT Search, Perplexity, and Google AI Overviews, traffic is shifting to AI answers. Here is the playbook to optimize your website for LLM citation algorithms.

The Paradigm Shift: From Blue Links to Citations

Classic search engines match keywords. AI search engines synthesize answers. To recommend your business, ChatGPT needs clear structured data, reference files (llms.txt), and crawl-ready content.

1. Implement Structured Schema Markup

LLMs crawl schema files first to establish entities. You must deploy comprehensive JSON-LD schemas representing your organization, services, and local locations.

2. Create a llms.txt File

Much like robots.txt tells crawlers what not to index, llms.txt provides LLMs with a clean, summarized markdown profile of your company, services, and credentials. Put this file in your public root directory.

3. Use Clear entity-based Copywriting

AI models understand context. Avoid keyword stuffing. Instead, format your content to directly answer user queries:

Poor: "We offer cheap GoHighLevel setups in Florida."

Optimized: "FHDTech provides GoHighLevel CRM setup sprints for HVAC and home service agencies, integrating custom pipelines and Twilio carriers."

4. Manage AI Crawler Permissions

Ensure your robots.txt allows crawlers like GPTBot, PerplexityBot, and ClaudeBot to access your informational pages while blocking them from scrapers that don't credit your site.
