Gemini is now the fourth engine Shruwd measures, beside Google AI Overviews, Google AI Mode and ChatGPT. Every plan gets it, the free one included, at the same price.
What changes
- Each measurement asks your prompts in the Gemini app too. It has its own tab after ChatGPT
on the overview, prompts, competitors and sources pages, and the API and the MCP server
take
engine=gemini. - Gemini's numbers start now, with no backfill. Until it has ten answers, its metrics show as insufficient data, never as zero.
- Findings read its answers and the pages it cites, as they do for the other engines.
- A robots.txt rule that blocks
Google-Extendedis now a critical finding. That token decides whether Gemini can use your pages in its answers, not only whether Google trains on them. AI Overviews and AI Mode don't read it.
Rechecks of earlier fixes
A fix marked applied before Gemini had a full 30-day baseline is judged on the engines it was measured against, and the finding says Gemini was left out, as it did for AI Mode. See rechecks.
Shruwd never signs in to Gemini: a data provider collects the app's answers. See where the answers come from.
