What exactly is AiVIS Cite Ledger?

AiVIS Cite Ledger is an evidence-backed AI citation audit and remediation system. It measures how AI models, ChatGPT, Perplexity, Claude, and Google AI, interpret, trust, and cite your web content. The result is a 0–100 CITE LEDGER score across seven weighted dimensions, with BRAG evidence-linked findings and prioritized fixes.

How is this different from Semrush, Ahrefs, or Clearscope?

Traditional SEO tools optimize for keyword ranking in traditional search results. AiVIS Cite Ledger audits citation readiness, the specific signals that determine whether AI answer engines retrieve and cite your content. A page can rank #1 on Google and be completely invisible to AI answer synthesis.

What is BRAG and how does it make findings trustworthy?

BRAG stands for Based-Retrieval-Auditable-Grading. It ties every audit finding to a real, traceable element on your page, a specific heading, schema block, meta tag, or content section, each carrying a unique evidence ID. You can open the element, verify the finding, and recheck it after a fix. No black boxes.

Is the free tier genuinely useful, or just a teaser?

The Observer (free) plan gives you a full composite CITE LEDGER score and all seven dimension letter grades, so you can see exactly where you stand and which categories are hurting you. BRAG evidence IDs and prioritized fix packs require a paid plan. Three audits per month, no credit card.

Your robots.txt Is Blocking ChatGPT, Claude, and Perplexity, And You Probably Do Not Know It | AiVIS Cite Ledger Blogs

By R. Mason · 2026-06-02 · 8 min read · SEO

A single Disallow: / under the wrong user-agent and your content will never enter an AI model index. Most teams never check. Here is the 30-second audit.

Key Takeaways

A Disallow: / under GPTBot, ClaudeBot, or PerplexityBot removes you from that platform's index entirely.
AI-crawler blocks usually arrive by accident via plugins, CDN/WAF toggles, or copied templates.
The free Robots Checker grades each crawler A–F separately and reads robots.txt, meta robots, and X-Robots-Tag.
An explicit Allow: / for a named bot overrides a wildcard block.
Technical SEO (crawl access, meta, headers) is a large share of the AiVIS citation score, analyzed by default, not a separate product.

Go check your robots.txt right now. Open yourdomain.com/robots.txt in a browser and look for these lines:

User-agent: GPTBot

User-agent: ClaudeBot

User-agent: PerplexityBot

If any of them is followed by Disallow: / then you have told that AI platform, in writing, not to crawl you. It will honor that. Your content will not enter its index, and it cannot be cited in answers, especially the time-sensitive ones that get regenerated from a live crawl.

This is the most common, most invisible AI-visibility failure we see. It is invisible because nothing breaks. Your rankings hold. Your analytics look normal. Google still sends traffic. But the moment a customer asks ChatGPT, Claude, or Perplexity about the problem you solve, you are simply not in the candidate set.

Why this happens by accident

Almost nobody sits down and decides to block AI crawlers. It happens three ways:

1. A security or "bot management" plugin adds blanket AI-crawler blocks in an update.

2. A CDN or WAF rule (Cloudflare, for example) flips on an "AI Scrapers and Crawlers" toggle.

3. A developer copies a robots.txt template from a forum that includes AI blocks "to be safe."

The result is the same: a directive you never reviewed is quietly removing you from the answer layer.

Who these crawlers actually are

Not all AI crawlers do the same job, and that matters for what you allow:

GPTBot, OpenAI training and browsing for ChatGPT. Critical.
ChatGPT-User and OAI-SearchBot, OpenAI live browse and SearchGPT. Critical.
ClaudeBot and Anthropic-AI, Anthropic, for Claude. Critical.
Google-Extended, Google's Gemini training control. Critical.
Googlebot and Bingbot, classic search index, but Bingbot also feeds Copilot. Critical.
PerplexityBot, Perplexity's research crawler.

Blocking a critical crawler is a direct hit to whether that platform can ever cite you.
