How to Optimize Your Website for Google-Extended

Google · Gemini & AI Overviews

Google-Extended is the web crawler operated by Google for Gemini & AI Overviews. Controls whether your content can be used to ground Gemini and Google AI features. This guide shows how to make your site readable and citable by Google-Extended.

Step 1: Allow Google-Extended in robots.txt

Make sure your robots.txt explicitly allows Google-Extended so it can fetch your pages:

User-agent: Google-Extended
Allow: /

Step 2: Serve content without JavaScript

Google-Extended can render some JavaScript, but server-rendered HTML is still more reliable. Use SSR or static generation so your content is in the initial response.

Step 3: Add structured data

Add JSON-LD with the schema.org types that match your pages (Organization, Article, FAQPage, HowTo) so the crawler can extract facts unambiguously.

Step 4: Make your content quotable

  • Answer the main question in the first sentence of each section.
  • Use ordered lists for steps and tables for comparisons.
  • Add a real FAQ with <details>/<summary> and matching FAQPage schema.
  • Show an updated date — freshness signals reliability.
