What is Google-Extended and why does it matter?

Google-Extended controls whether Gemini can train on and cite your content. Googlebot is for search indexing; Google-Extended is for AI grounding. Blocking Google-Extended means Gemini will never reference your site.

How do I optimize for the Knowledge Graph?

Add Organization schema with your brand name, logo, and sameAs array linking to your YouTube channel. This helps Gemini understand your brand identity and link your videos to your domain.

Why manually edit YouTube captions?

Gemini can watch videos by parsing transcripts. Auto-captions miss entity names and technical terms. Manual editing ensures accuracy for AI comprehension.

What makes Gemini different from other AI agents?

Gemini has native YouTube access (1B+ videos), Knowledge Graph integration (500B+ entities), and 1M token context window (5× larger than GPT-4). This creates unique optimization opportunities.

How to get Gemini to find your website

Key Difference: Google-Extended (not Googlebot) controls Gemini grounding.

robots.txt: User-agent: Google-Extended + Allow: / (separate from Googlebot!)
Add Organization schema: {"@type":"Organization","sameAs":["https://youtube.com/@your-channel"]}
Manually edit YouTube captions in YouTube Studio (auto-captions miss entities)
Use semantic HTML: <h1> not <div class="header">
Create comprehensive guides (10,000 words > 10× 1,000-word posts)
Test: Ask Gemini to browse your URL and verify extraction

Gemini Advantages: Native YouTube transcript parsing, Knowledge Graph integration, 1M token context (700K words), real-time Google Search grounding.
