What happens during a diagnostic
01
Query generation
We generate 50+ queries your potential customers would ask — "best [service] in [city]", "top [industry] tools", comparison and problem-solution queries.
02
Cross-platform testing
Each query runs against ChatGPT, Claude, Perplexity, and Gemini via their production APIs in real time.
03
Analysis & fixes
We calculate mention rates, run 14 technical checks, surface response insights, and generate AI-powered implementation fixes for every issue found.
The 14-check technical audit
Every diagnostic includes a technical GEO audit scored out of 15 points. These checks measure how well your site is structured for AI platforms to discover, understand, and cite your business.
llms.txt file
Emerging standard for AI crawler communication — provides structured business info for LLMs.
AI crawler access
Checks robots.txt for GPTBot, ClaudeBot, Google-Extended, PerplexityBot, and other AI crawlers.
Schema.org markup
Detects structured data types (Organization, Product, Service, etc.) that AI can parse reliably.
FAQ / HowTo schema
Structured Q&A and instructional content that AI platforms frequently cite in responses.
Speakable schema
Markup that helps voice assistants and AI identify content suitable for spoken responses.
JavaScript bundle size
Heavy JS can prevent AI crawlers from fully rendering your content.
Image alt text coverage
Alt text helps AI understand visual content and improves overall content comprehension.
Content freshness signals
dateModified, datePublished, and other timestamps that signal up-to-date information.
Sitemap availability
XML sitemaps help AI crawlers discover and understand your site structure.
AI info page
Dedicated page for AI systems with business overview, pricing, and FAQ schema (worth up to 2 points).
Canonical URL
Proper canonical configuration prevents duplicate content confusion for AI crawlers.
Meta completeness
Title, description, OG tags, and other meta that AI uses to understand page purpose.
Schema field completeness
Validates that detected schema types have all required fields populated.
Heading structure
Proper H1/H2 hierarchy that AI uses to understand content organization and topics.

Common questions
How accurate is AI visibility testing?
Prelio tests real-time responses from production AI platforms using their official APIs. Results reflect your actual presence at the time of testing. Each diagnostic runs 50+ queries across 4 platforms.
Why do results differ between platforms?
Each AI platform has unique citation behaviors. ChatGPT may prioritize different factors than Claude or Perplexity. Some platforms favor structured data, others prioritize recency or authority. Platform-specific differences reveal where to focus optimization.
What if my business isn't mentioned at all?
Zero visibility is common for businesses that haven't optimized for AI. Common causes: blocking AI crawlers in robots.txt, missing structured data, thin content, or low authority signals. Prelio's AI-generated fixes provide specific steps to establish baseline visibility.
How often should I test?
Prelio runs diagnostics automatically based on your plan — monthly (Starter), weekly (Pro), or daily (Hypergrowth). You can also run on-demand checks anytime. After major website changes, results typically update within 4–6 weeks as AI platforms recrawl.
How is this different from traditional SEO?
Traditional SEO optimizes for search result rankings. AI visibility measures whether you're cited in AI-generated responses. You can rank #1 on Google but be invisible to ChatGPT. AI visibility requires additional optimization: structured data, llms.txt, AI crawler access, and content depth.
What's the relationship between the technical score and mention rate?
The 14-check technical audit (scored out of 15) measures how well your site is structured for AI platforms. Mention rate (0–100%) measures how often you actually appear in responses. A high technical score creates the foundation — but mention rate also depends on content quality, authority signals, and competitive landscape.
