What is Causabi and what does the name mean?

Causabi is a GEO (Generative Engine Optimization) platform that helps businesses appear in ChatGPT, Perplexity and Gemini answers. The name comes from the Latin word causa — meaning reason, cause. The idea: Causabi gives your business the reason AI search engines mention and recommend you.

What is GEO optimization and how does it differ from SEO?

GEO (Generative Engine Optimization) is the practice of optimizing your website for AI search engines: ChatGPT, Perplexity, Gemini, Yandex GPT. Unlike traditional SEO (Google rankings), GEO affects whether AI cites your business in its answers. 73% of AI queries end without a click — AI gives the answer directly from your content.

How does Causabi improve ChatGPT visibility?

The tool generates FAQ Schema (gives +41% citation rate increase per Perplexity data), fixes robots.txt so GPTBot and ClaudeBot can crawl your site, creates llms.txt — the standard for direct LLM communication, and adds Schema.org markup for entity recognition in AI.

What is llms.txt and why do I need it?

llms.txt is a new standard (Jeremy Howard, fast.ai, 2024) for sites that want to explicitly explain their structure and content to AI agents. The file is placed at the site root and read by ChatGPT Browse, Claude Tools, Perplexity. As of April 2026, adopted by 12,000+ sites including Anthropic, Cloudflare, Vercel.

How much does Causabi cost?

Currently free in Early Access preview. The free plan includes 1 site, AI Readiness Score, llms.txt generation, Schema.org and robots.txt. Pro plan (after preview launch) includes unlimited sites, weekly ChatGPT/Perplexity monitoring and automatic regeneration.

How fast does the site analysis work?

Full AI audit takes 30–90 seconds. The tool scans up to 8 key pages, checks robots.txt, Schema.org markup, FAQ blocks, content depth and brand signals. Result: Score 0–100 with detailed breakdown and specific fix recommendations.

Do you need access to my CMS or server?

No. Just the URL. You download a ZIP of generated files and upload them yourself — or use the hosted AI profile on causabi.com which AI bots already index.

How long until my business appears in ChatGPT after optimization?

Hosted profile on causabi.com is indexed by AI bots in 1–7 days. Files on your own site take 2–4 weeks depending on ChatGPT and Gemini crawl frequency.

How does AI citation monitoring work?

Once a week we run each of your target queries through ChatGPT and Google AI. We check: is your business mentioned, what position, who are the competitors nearby. All in a dashboard with trend.

Is Causabi open source?

Yes, the core (causabi-geo CLI) is on PyPI under MIT license. pip install causabi-geo — run analysis and generate files locally without signing up.

Make Your Site Visible in ChatGPT Using Claude Code

Claude Code runs in your terminal and reads your entire codebase before making changes. It understands your framework, finds the right files, and adds GEO optimization assets correctly — no guessing required.

Why Claude Code works especially well

Unlike other AI tools that work file-by-file, Claude Code sees your whole project at once. It knows if you're using Next.js App Router vs Pages Router, where your public directory is, and how your layout is structured — so Schema.org ends up in exactly the right place.

What we'll add:

✅ Organization Schema — AI correctly identifies your business
✅ FAQ Schema — +41% citation rate in AI responses
✅ robots.txt — allow GPTBot, ClaudeBot, PerplexityBot
✅ llms.txt — AI agents understand your site instantly

Generate your GEO assets first

Go to causabi.com
Enter your site URL and run the audit
Download the ZIP — it contains Schema.org, FAQ Schema, llms.txt, and robots.txt

Install Claude Code (if not already installed)

Terminal

npm install -g @anthropic-ai/claude-code

Then run claude in your project directory and sign in with your Anthropic account.

Paste the GEO optimization prompt

Open Claude Code in your project root and send this message. Replace the placeholders with your actual content from Causabi.

Claude Code Prompt

I need to add GEO optimization to this site so it gets cited in ChatGPT, Perplexity, and other AI search engines. Please do all of the following: 1. Add Organization Schema JSON-LD to the <head> of every page: [PASTE YOUR ORGANIZATION SCHEMA FROM CAUSABI] 2. Add FAQ Schema JSON-LD to the homepage <head> only: [PASTE YOUR FAQ SCHEMA FROM CAUSABI] 3. Create or update the robots.txt file to allow AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Bytespider). 4. Create an llms.txt file with this content: [PASTE YOUR LLMS.TXT CONTENT FROM CAUSABI] Use the correct approach for this project's framework. Make sure all files end up in the right locations.

What happens next

Claude Code will read your project, identify the framework (Next.js, Vite, Astro, etc.), and make all the necessary file edits. It will show you exactly what it's changing before applying. For Next.js, it automatically uses app/layout.tsx for App Router or pages/_document.tsx for Pages Router.

Deploy and verify

Deploy your changes (Claude Code can also help with this)
Check your-site.com/robots.txt and your-site.com/llms.txt
Go to causabi.com → run a new audit — score should reach 70+
Validate Schema: validator.schema.org

Bonus: Automate with the MCP server

If you want Claude Code to automatically generate and apply GEO assets for any project, install the Causabi MCP server:

npm install -g geo-optimizer-mcp

Then tell Claude Code: "Use the geo-optimizer MCP to optimize this site." It handles everything automatically.

Generate your GEO files for free

Causabi creates Schema.org, FAQ Schema, llms.txt, and robots.txt tailored to your specific site — ready for Claude Code to apply.
