How to Check If ChatGPT Knows About Your Website

The test takes 5 minutes. The answer might surprise you.

There's a new way to check whether your marketing is working: ask an AI about your product. If ChatGPT, Perplexity, or Claude can accurately describe what you do — you're visible. If they can't — you have a problem that's costing you traffic every day.

Here's exactly how to test your AI visibility right now.

Step 1: Ask ChatGPT

Open ChatGPT and ask:

"What is [your product name]?"

Then try:

"What does [your product name] do?"

And:

"What are the best tools for [your product category]?"

What good results look like

A good response accurately describes:

• What your product is
• What problem it solves
• Key features or differentiators
• Possibly your pricing or target audience

What bad results look like

• "I don't have information about [product name]." — ChatGPT's crawler (GPTBot) hasn't been able to read your site.
• Vague or generic answer — GPTBot found minimal content. Your site probably has a visibility gap.
• Completely wrong information — GPTBot found outdated or incorrect content. Your site may need better structured data.
• Competitor mentioned instead of you — Your competitors are visible to AI; you're not.

Step 2: Ask Perplexity

Open Perplexity and ask the same questions. Perplexity is especially useful because it shows its sources — you can see exactly which URLs it cited.

Check:

• Does it mention your site at all?
• Does it cite your URL as a source?
• Is the information accurate and current?
• Are your competitors cited but you're not?

Perplexity uses PerplexityBot to crawl websites. If your site is a JavaScript SPA, PerplexityBot sees only the raw HTML — likely an empty shell.

Step 3: Ask Claude

Open Claude and ask:

"Tell me about [your product name]. What is it and who is it for?"

Claude uses ClaudeBot to crawl websites. Same limitation as the others — it doesn't execute JavaScript.

Step 4: Ask Gemini

Open Gemini and ask the same questions. Gemini has access to Google's search index, so it may know about your site even if other AI systems don't — but its answers still reflect how well your content is structured for AI understanding.

Why AI might not know about you

If the results from all four tests were disappointing, here are the most common reasons:

1. Your site is a JavaScript SPA

This is the #1 cause. If your site is built with React, Vue, Angular, or generated by an AI builder (Lovable, Bolt.new, Base44), the content is rendered by JavaScript in the browser. AI crawlers don't execute JavaScript — they see an empty HTML page.

How to check: Run curl -s https://your-site.com | wc -w in your terminal. If the word count is under 50, crawlers see almost nothing.

2. Your robots.txt blocks AI crawlers

Some sites accidentally (or intentionally) block AI bots. Check your robots.txt:

curl https://your-site.com/robots.txt

Look for lines like:

User-agent: GPTBot
Disallow: /

If AI bots are blocked, they can't crawl your site at all.

3. Your site is too new

AI crawlers need time to discover and index your site. If you launched recently, it may take weeks to months for AI systems to build knowledge about your product.

4. Your content lacks entity clarity

AI systems need clear, specific descriptions to understand what you are. If your homepage says "We help businesses grow" without ever specifying what your product actually does — AI systems won't have enough to work with.

5. Your content isn't citable

AI systems prefer to cite sources with specific data, unique insights, or authoritative information. Generic content that repeats what everyone else says rarely gets cited.

How to fix it

If your site is a JavaScript SPA

You need to serve rendered HTML to AI crawlers. The fastest path:

1. Run a CrawlReady audit to see your exact visibility gap
2. Deploy pre-rendering to serve complete HTML to all crawlers
3. Re-test by asking AI systems about your product in 2–4 weeks

If your robots.txt blocks AI crawlers

Update your robots.txt to allow AI bots:

User-agent: GPTBot
Allow: /

User-agent: ChatGPT-User
Allow: /

User-agent: ClaudeBot
Allow: /

User-agent: PerplexityBot
Allow: /

If your content lacks entity clarity

Rewrite your homepage and key pages to clearly state:

• What your product is (in the first paragraph)
• Who it's for
• What problem it solves
• How it works
• What makes it different

Be specific. Use your product name. Mention your category. AI systems build knowledge graphs from these explicit connections.

If your site is new

Be patient — but proactive:

• Submit your sitemap to Google Search Console
• Make sure AI crawlers aren't blocked
• Create content worth citing (case studies, original data, unique guides)
• Build inbound links from sites AI systems already trust

Set up ongoing monitoring

Don't just test once. Make AI visibility testing a regular practice:

• Monthly: Ask all four AI systems about your product. Screenshot the results.
• After major content updates: Re-test to see if AI knowledge has updated.
• Track AI referral traffic: In your analytics, monitor traffic from chatgpt.com, perplexity.ai, and other AI referrers.
• Run periodic audits: Use the CrawlReady audit tool to verify what crawlers see after any site changes.

Over time, you'll build a clear picture of your AI visibility trajectory — and you'll catch regressions before they cost you traffic.

What happens when you become AI-visible

When AI systems can accurately describe your product:

• ChatGPT mentions you when users ask about your category
• Perplexity cites your site as a source in relevant answers
• AI referral traffic starts showing up in your analytics
• Social sharing works properly (link previews are complete)
• Traditional SEO improves because the same fixes help Google too

This is the compounding advantage of AI visibility: once AI systems know about you, they cite you in answers, which drives traffic, which creates more signals, which reinforces your AI presence.

Start with the test

Open ChatGPT right now. Ask it about your product. The answer tells you everything you need to know about your current AI visibility — and whether you need to act.

If AI doesn't know you exist, run a free CrawlReady audit to find out why.

AI system knowledge is dynamic and varies by platform. Results from these tests reflect each AI system's current knowledge as of when you run them. Regular testing is the only way to track your visibility over time.
