How to get cited by ChatGPT and Perplexity

Getting cited by ChatGPT and Perplexity is not luck — it is Generative Engine Optimization (GEO) applied consistently. LLMs reach for sources that are fast, structurally clear, explicitly permitted to crawl, and written in extractable language.

This is the playbook LuminaForge ships on every build — including luminaforge.ai itself.

Step 1: Allow AI crawlers explicitly

Most sites block LLM bots by accident. In robots.txt (or app/robots.ts on Next.js), allow every published AI user agent:

• GPTBot, OAI-SearchBot, ChatGPT-User
• PerplexityBot, Perplexity-User
• ClaudeBot, Claude-Web, anthropic-ai
• Google-Extended, Applebot-Extended
• CCBot, Bytespider, Amazonbot

Verify with LuminaForge robots.txt as a reference implementation.

Step 2: Publish llms.txt and llms-full.txt

Place a compact brief at /llms.txt and an extended entity reference at /llms-full.txt. Include company name, services, canonical URLs, FAQ summaries, and citable statistics.

LLMs treat these files as a curated map of your domain — similar to how search engines use sitemaps.

Step 3: Install comprehensive JSON-LD

At minimum:

• Organization + WebSite on the root layout
• FAQPage on every page with meaningful Q&A
• BreadcrumbList on all nested routes
• Article on blog posts and case studies
• Service on service detail pages

Validate with Google's Rich Results Test before shipping.

Step 4: Write for extraction, not decoration

LLMs quote:

• Lists (ordered and unordered)
• Tables and definition lists (<dl>)
• First paragraphs under headings
• Explicit entity language — spell out company name, services, locations

They struggle with:

• Vague pronouns ("we believe…")
• Stats buried in prose without sources
• FAQ questions written as keyword fragments

Use cite attributes on statistics. Link to authoritative sources.

Step 5: Build a query bank and track weekly

Define 20–50 conversational questions you want to win. Run them weekly through ChatGPT, Perplexity, Grok, and Claude. Log:

1. Citation presence — did your domain appear?
2. Citation position — first source or buried?
3. Snippet context — what was quoted?

LuminaForge publishes live snapshots on the transparency dashboard. Client portals include the same weekly delta reports.

Step 6: Ship performance that crawlers respect

Slow pages get deprioritized. We engineer Core Web Vitals in the green on mobile and Lighthouse Performance in the high 90s on production marketing routes — verified on our transparency dashboard. Speed is a trust signal for both Google and LLM crawlers indexing your content.

Common mistakes

Mistake	Fix
Blocking GPTBot in robots.txt	Explicit allow rules for all AI crawlers
No llms.txt	Publish compact + full brief at domain root
Keyword-stuffed FAQ	Write questions as full conversational sentences
No measurement	Weekly query bank + public citation log
