01What the AI SEO audit checks
Six things that decide whether AI answers mention you
Content without JavaScript
Most AI crawlers don't execute JavaScript. The audit flags pages whose main content only appears after client-side rendering, so you know what an AI bot actually receives.
Entities & structured data
Validates JSON-LD and looks for the Organization and FAQPage schema that help engines connect your brand, products and answers to a known entity.
Citability
Measures fact and statistic density and question-style headings — the self-contained, quotable passages AI answers tend to cite.
Trust signals (E-E-A-T)
Checks for authorship, published and updated dates, outbound citations and other signals that a page is written by someone accountable.
llms.txt
Detects an llms.txt file — an emerging convention that gives language models a curated map of your most important pages.
02AI SEO vs. traditional SEO
Same foundations, different reader
An AI website audit doesn't replace a technical SEO audit — AI engines lean on the same crawlable, fast, well-structured pages. It adds the checks that matter when the reader is a language model choosing what to quote. That's why Site Audit Score runs both in one report.
| Traditional SEO | AI search | |
|---|---|---|
| Who reads the page | Googlebot and Bingbot | OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended and others |
| JavaScript | Google renders it, eventually | Most AI crawlers read raw HTML only |
| What wins | The best-ranked page for a query | The clearest, most quotable passage |
| Key signals | Links, relevance, Core Web Vitals | Crawler access, entities, facts, structure |
| Success looks like | A blue link and a click | A citation or brand mention inside an answer |

How to improve your AI search visibility
- 01
Decide which AI crawlers to allow
Search crawlers such as OAI-SearchBot and PerplexityBot decide whether you can appear in AI answers; training crawlers such as GPTBot are a separate choice. Write explicit rules with the robots.txt generator, then confirm them with the AI crawler checker — CDNs and bot-protection can block bots your robots.txt allows.
- 02
Serve your core content as HTML
Make sure headings, product descriptions and answers exist in the server response, not only after hydration. Server rendering or static generation solves this for most frameworks.
- 03
Write answer-first sections
Lead each section with a direct, specific answer, then support it with numbers and sources. Phrase key headings as the questions people ask. The GEO Grader scores a passage for this.
- 04
Describe your entity with schema
Add Organization schema with your logo, founder and social profiles, and Product or SoftwareApplication schema for what you sell. Keep it consistent with what the page says.
- 05
Add an llms.txt file
It takes minutes: list your key pages with one-line descriptions. The llms.txt generator builds one from your sitemap.
- 06
Re-audit after every change
Deploys quietly break robots rules, canonicals and schema. Re-run the AI & GEO module after changes, or let drift monitoring flag them.

AI SEO audit questions
Still unsure? Email contact@siteauditscore.com and you'll hear back from the person who built it.
What is an AI SEO audit?
An AI SEO audit checks whether AI-powered search engines — ChatGPT search, Google AI Overviews and Gemini, Perplexity and Claude — can reach your pages, understand what they are about and quote them. It covers AI crawler access in robots.txt, server-rendered content, structured data, citability and trust signals, alongside the technical SEO those engines also rely on.
Is this AI SEO audit free?
Yes. The audit on this page is free and needs no signup. It runs all 17 quick-scan modules, including the AI & GEO visibility module, and shows your scores and top fixes. A free account adds the full issue list with fixes and 100 credits for more pages.
Does blocking GPTBot remove me from ChatGPT?
Not necessarily. OpenAI uses GPTBot for model training and OAI-SearchBot for ChatGPT search results. You can block training while allowing search. The audit reports each user agent separately so you can make that choice deliberately.
Can an audit tell me if ChatGPT already cites my site?
No tool can see inside a model, and answers vary by user and prompt. What the audit can do is remove the technical reasons you would not be cited — blocked crawlers, JavaScript-only content, missing entity data — and show how quotable your content is. To check real citations, ask the engines your key questions and look for your domain in the sources.
How is an AI SEO score calculated?
The AI & GEO module starts at 100 and subtracts points for each issue by severity: blocking every AI crawler or lacking authority signals costs more than a missing llms.txt file. It is reported on its own and also counts toward your overall weighted SEO score.
