Is Your Website Invisible to AI Search?

Ranking #1 on Google doesn't mean ChatGPT or Perplexity can find you. Paste your page's HTML source below and check whether AI search engines can actually read and cite your content.

Why This Tool Exists

Ranking #1 on Google no longer guarantees customers can find you. AI tools like ChatGPT, Perplexity, and Google's AI Overviews now answer questions directly — and if they can't properly read your site, they skip it entirely, even if it ranks perfectly on a traditional search results page.

Industry projections suggest a majority of global searches will be "zero-click" by 2026 — the answer given directly by an AI, no visit to your site required. Getting cited inside that answer is now as important as ranking for the click itself.

This AI search visibility checker runs 18 checks based on the exact patterns I look for when auditing client websites — the same technical and content signals that determine whether ChatGPT, Perplexity, and AI Overviews can read, understand, and cite your page. It's completely free, with no signup required, and runs entirely in your browser.

Schema.org markup for AI understanding
2. FAQ Schema

13. Placeholder Images
Unreplaced "dummy" template images
14. Template Placeholder Text
"yourdomain.com," unfinished copy
15. Heading Structure
Skipped heading levels (H1 → H4)
16. Alt-Text Coverage
% of images with descriptive alt text
17. HTML Lang Attribute
Missing language declaration
18. Canonical / og:url Match

How We Calculate Your Score

Not every issue matters equally, so this tool doesn't treat them equally. Each of the 18 checks is assigned a weight based on how much it actually affects whether AI tools can find and cite your page:

Critical (weight 2-3)Structured data, noindex tags, HTTPS, JavaScript-rendering, placeholder/duplicate content — issues that can block AI visibility entirely.
Standard (weight 1)Meta description, alt text, heading structure, link text — issues that reduce quality without blocking visibility outright.

Your final score is the sum of points earned divided by total possible points, so a single critical issue affects your score more than several minor ones — matching how these issues actually affect real-world AI visibility.

Frequently Asked Questions

What is an AI Search Visibility Checker?

An AI Search Visibility Checker analyzes whether AI search engines like ChatGPT, Perplexity, and Google AI Overviews can read, understand, and cite a webpage — checking technical factors like structured data, crawlability, and content structure that determine AI visibility, separate from traditional Google ranking factors.

Why can a website rank #1 on Google but be invisible to ChatGPT?

Google ranking and AI search visibility are evaluated differently. A page can rank well in traditional search while still being unreadable to AI crawlers due to heavy JavaScript rendering, missing structured data, or content that isn't structured for direct-answer extraction — all of which this tool checks for.

Is this AI visibility checker really free?

Yes. The tool runs entirely in your browser with no signup, no email required, and no limit on how many pages you can check.

How do I get my page's HTML source to paste into the tool?

Right-click anywhere on your webpage, select "View Page Source," then select all (Ctrl+A or Cmd+A) and copy (Ctrl+C or Cmd+C). Paste the copied code into the tool's input box above.

Does a high score guarantee AI search visibility?

A high score means your page has the technical foundation AI search engines look for, which significantly improves your odds of being read and cited. It doesn't guarantee citation on every query, since AI tools also weigh content relevance and authority — but it removes the technical barriers that block visibility entirely.

What is Generative Engine Optimization (GEO)?

GEO is the practice of structuring website content so generative AI search engines can extract, quote, and cite it directly in their answers, rather than optimizing purely for traditional ranked search results.

What's the difference between an AI visibility audit and this free checker?

A full AI visibility audit typically tracks how a brand is cited across dozens or hundreds of real AI prompts over time, often using paid enterprise tools. This free checker does something more immediate: it inspects a single page's actual HTML for the technical and content issues that block AI crawlers in the first place — the foundation an audit would otherwise flag as broken.

What is Answer Engine Optimization (AEO)?

AEO is the practice of structuring content to directly answer the specific questions people ask AI assistants and voice search tools, using clear headings, FAQ formats, and concise direct answers — closely related to GEO, with a stronger focus on question-and-answer content structure.

Real Audits I've Run

A luxury hotel brand's site claimed a wedding venue had views of a city in a different country entirely — a leftover template error that had gone unnoticed for months.
A well-known local business's homepage was set to "noindex" — invisible to Google entirely — despite being a real, actively-operating company.
A heritage brand's entire "Customer Reviews" section turned out to be unedited placeholder text, marked as "Verified" — visible to every visitor for who knows how long.
