Free checker shows which pages Google's Gemini cites for a customer's question
The Gemini Grounding Gap Checker, a free tool built by the writer behind suganthan.com, asks Google's Gemini AI the same question several times and counts which pages it cites. It then compares those answers with a page from your site and suggests edits for the gaps. The developer is clear that a closer match does not guarantee a citation, and his own tests found that some repeated claims were outdated. Check each suggestion before adding it. He also reports that sites whose robots.txt file, the instructions a site gives web crawlers, blocks Google-Extended went uncited in his tests.
- For
- Detroit creatives and small business owners with a website who want to understand why AI answers from Google point customers to competitors, and who can edit their own page text.
- Cost
- Free, according to the developer. Each connection gets about three full checks a day plus rewrite tests. A ten-run check uses about two of those daily checks. A daily budget is shared by all visitors, so the tool can run out on a busy day.
- Time
- The default five-run check takes 30 seconds to a minute, per the developer. Rewrite tests reuse earlier results and take seconds.
- Access
- Open online with no stated sign-up; a Turnstile screen filters bots before a check runs. Enter one search-style question plus a page URL, pasted text, or 'No page yet.' Pages that load their content through JavaScript should use Paste content, though pasted text cannot be matched to cited URLs. Reports live only in the browser tab unless exported as HTML, Markdown, JSON or CSV.
Your moveRun one question a real customer would search through the checker, then open your site's robots.txt file (yoursite.com/robots.txt) to see whether it blocks Google-Extended before editing any pages.
