Is Google-Extended blocked on your site?
Google-Extended is the Gemini & AI Overviews crawler that collects pages used to train the model. If your robots.txt blocks it, that engine cannot read your pages, and a page it cannot read is a page it can never cite.
Free, no sign-up. We fetch one public file and read it. Nothing is stored.
Questions
- What does Google-Extended do?
- Google-Extended is used by Gemini & AI Overviews. It collects pages used to train the model.
- Should I block Google-Extended?
- That is a real trade-off, not a bug to fix. Blocking it keeps your content out of model training, but can also reduce how well the assistant knows you. Blocking a TRAINING crawler is a defensible choice; blocking a SEARCH or live-browsing crawler is what actually costs you citations.
- Is this check free?
- Yes, and there is no signup. We fetch one public file, robots.txt, and read the rules for this user-agent. You see the full result, including every failure we find.
