Features & Capabilities

GEO Checker: AI Indexing & llms.txt Audit Check if any website is ready for Generative Engine Optimization (GEO). Audit llms.txt, robots AI bots, sitemap, schema and meta, then copy a ChatGPT prompt to test what AI already knows about the brand.

🚀 Why Choose GEO Checker? AI assistants and generative search do not see your site the way classic crawlers do. GEO Checker turns your browser into a focused readiness suite so you can score the active tab, spot missing AI signals, and smoke-test brand knowledge in ChatGPT, Claude, or Perplexity in one flow.

📋 What GEO Checker Audits Stop guessing whether AI systems can understand your site. The checklist covers the signals that matter for GEO and AI indexing:

AI files: llms.txt and llms-full.txt presence, plus detection when a path is really an HTML SPA soft-404 instead of plain text or markdown.
robots.txt AI bots: GPTBot, ChatGPT-User, Google-Extended, ClaudeBot, PerplexityBot, and related AI crawler rules.
Discovery basics: sitemap.xml reachability and on-page indexability (noindex).
On-page structure: Schema.org JSON-LD, title and meta description, canonical URL, Open Graph.
Readiness score: one clear score from the checklist so you know what to fix first.

🔥 Top Professional Features

Live Active-Tab Scan: Open any https site, click the icon, and get a fresh GEO checklist without leaving the page.

SPA Fallback Detection: Catch fake 200 homepage HTML on /llms.txt, /robots.txt, and similar paths that break AI scanners.

AI Knowledge Prompt Packs: One-click copy prompts for ChatGPT, Claude, and Perplexity with the domain, score, and gaps filled in.

Rescan in One Click: Fix a file or meta tag, rescan the same tab, and confirm the score moved.

Free Core Forever: Full checklist and prompt packs stay free. Optional "tools we recommend" links stay disclosed if enabled.

🛠 Built for Founders, SEOs & Agencies Whether you ship a product site, run technical SEO, or audit client domains for AI visibility, GEO Checker is a fast visual alternative to hand-checking robots, llms.txt, and schema in DevTools. It is a practical companion for modern Firefox workflows, not a slow full-site crawler.

Install GEO Checker and make sure generative engines can actually understand your site.

Is GEO Checker: AI Indexing & llms.txt Audit Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

GEO Checker: AI Indexing & llms.txt Audit requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

GEO Checker: AI Indexing & llms.txt Audit is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
