Is Your Site Visible
on ChatGPT? 2026 AI SEO Guide

📅 June 8, 2026 ✍️ Scanliq Team ⏱️ 7 min read

By 2026, a significant portion of web traffic comes from AI systems like ChatGPT, Perplexity and Google AI Overview. Yet most website owners still haven't asked the key question: "Is AI even aware my site exists?"

Important: The fundamentals of traditional SEO and AI SEO are similar, but AI systems evaluate content differently. This guide covers the differences and exactly what you need to do.

How Do AI Search Engines Work?

When ChatGPT answers a question, it either browses the web in real time or refers to sites in its training data. Perplexity relies entirely on real-time web browsing. Both filter sources based on specific criteria.

How AI Systems Evaluate Websites

Criterion	ChatGPT	Perplexity	Google AI
HTTPS	✅ Required	✅ Required	✅ Required
robots.txt permission	✅ Critical	✅ Critical	✅ Critical
Meta description	✅ Important	✅ Important	✅ Important
Schema.org	⚠️ Recommended	✅ Important	✅ Critical
llms.txt	✅ Recommended	⚠️ Developing	⚠️ Developing

AI SEO Checklist — 2026

1. Allow GPTBot and Other AI Bots

Make sure your robots.txt isn't blocking AI bots. Check for these bots:

robots.txt — Allow AI Bots

User-agent: GPTBot
Allow: /

User-agent: ClaudeBot
Allow: /

User-agent: PerplexityBot
Allow: /

User-agent: Google-Extended
Allow: /

2. Write Strong Meta Descriptions

AI systems use meta descriptions as page summaries. Write clear, keyword-rich descriptions between 120-160 characters.

3. Add Schema.org Structured Data

Structured data tells AI what your content is about in machine-readable language. See our Schema.org guide for step-by-step instructions.

4. Write Content in Q&A Format

AI systems scan sites to answer questions. Organize your content around formats like "What is X?", "How to do X?" and add FAQ sections.
