AI Visibility Audit:Find What AI SearchEngines Cannot See.
VektorAI analyzes over 100 SEO, AEO, and GEO signals on any URL — showing you exactly what stops ChatGPT, Perplexity, and Google AI Overviews from citing your content.
◈ The shift
AEO and GEO: Optimizing for the AI Answer Layer
In 2025, generative AI platforms such as ChatGPT, Perplexity, and Google AI Overviews became primary information sources for millions of users. Unlike traditional SEO — which focuses primarily on keyword placement and backlinks — AEO and GEO optimize the structured signals and content quality that AI engines require before they will cite a page. According to generative engine optimization research, pages with complete structured data and strong E-E-A-T signals are significantly more likely to appear in AI-generated answer panels. For example, a page with a complete FAQPage schema and a direct-answer opening paragraph consistently outperforms unstructured content in AI citation frequency.
AEO — Answer Engine Optimization
AEO targets visibility in AI-generated answers by ensuring your page has the right machine-readable signals: JSON-LD schemas, Open Graph tags, Twitter Cards, AI bot access in robots.txt, and a structured llms.txt file. Without these, AI engines cannot reliably identify or trust your page.
GEO — Generative Engine Optimization
GEO goes deeper — it optimizes the content itself to be selected and quoted by generative AI. This means strong E-E-A-T signals (author credentials, editorial review), highly quotable paragraphs, authority citations, content comprehensiveness (800+ words), and query-aligned titles and headings.
"According to a 2025 Schema.org adoption study by W3Techs, only 22% of websites implement JSON-LD structured data — leaving 78% without the markup that AI engines rely on for citation and answer generation."

AEO gets you indexed. GEO gets you cited. VektorAI audits both — compared to checking signals manually, our automated audit covers 100+ rules in under 30 seconds.

◈ The problem
Why Are AI Search Engines Ignoring Your Content?
AI search engines such as ChatGPT Search, Perplexity, and Google AI Overviews do not guess. When they cannot find the right structured signals on your page, they move to a competitor page that has them. Every missing tag is a missed citation.
The five most common reasons AI engines skip your content:
- ✕Missing JSON-LD schemas
Without FAQPage, Organization, or Article schemas, AI engines have no machine-readable context to cite from.
- ✕AI bots blocked in robots.txt
Disallowing GPTBot, ClaudeBot, or Google-Extended prevents AI indexing entirely, regardless of content quality.
- ✕No llms.txt file
AI crawlers cannot efficiently discover your key pages without a structured llms.txt at your domain root.
- ✕Incomplete Open Graph tags
Missing og:title or og:description causes AI crawlers to fabricate summaries — often inaccurately — rather than cite you.
- ✕Weak E-E-A-T and content signals
No author credentials, thin content under 800 words, no statistics, and no direct-answer paragraph — generative AI skips content it cannot confidently quote.

◈ FAQ
Frequently Asked Questions
What is AEO (Answer Engine Optimization)?
▶
AEO is the practice of optimizing web content so that AI-powered search engines like ChatGPT, Perplexity, and Google AI Overviews can accurately understand, extract, and cite your content. It covers structured data markup (JSON-LD), Open Graph tags, Twitter Cards, AI bot access rules in robots.txt, and llms.txt — all signals that help machines read and trust your pages.
What is GEO (Generative Engine Optimization)?
▶
GEO optimizes your content to be selected and quoted by generative AI when composing answers. While AEO handles metadata signals, GEO focuses on content quality: E-E-A-T trust (author credentials, editorial review), quotability (direct-answer paragraphs, statistics, TL;DR sections), citation depth (authority links, attribution phrases), content comprehensiveness (800+ words, examples), and query alignment (intent-matching titles, FAQ sections, question headings).
How does VektorAI audit my page for AI visibility?
▶
VektorAI fetches your page server-side and analyzes over 100 signals across four categories: SEO (title, meta, headings, images, links), AEO (Open Graph, JSON-LD schemas, robots.txt, llms.txt), GEO (E-E-A-T signals, content quotability, citation depth, content depth, query alignment), and Performance (Core Web Vitals via Google PageSpeed Insights).

Unlock the full report (one-time $9) to see every issue with copy-paste code fixes, or go Pro for unlimited audits and AI-powered suggestions.
Why is my content not appearing in AI search answers?
▶
The most common causes are: missing JSON-LD schemas (FAQPage, Organization), incomplete Open Graph tags, AI bots blocked in robots.txt (GPTBot, ClaudeBot), a missing llms.txt file, thin content under 300 words, no author credentials or E-E-A-T signals, and an opening paragraph that does not directly answer the user query. VektorAI identifies all of these with specific fixes for each.
What is llms.txt and why does it matter?
▶
llms.txt is a plain-text file at your website root that helps AI crawlers understand your site structure and key pages. A well-structured llms.txt with a title, section headers, and markdown links significantly improves your content discoverability by AI systems. VektorAI checks whether it exists, has an H1 title, section headers, links, and sufficient word count.
What SEO, AEO, and GEO checks does VektorAI perform?
▶
VektorAI performs over 100 checks. SEO: title length, meta description, canonical, viewport, heading hierarchy, image alt/WebP, link quality, sitemap, content depth. AEO: full Open Graph set, Twitter Cards, JSON-LD schemas (FAQPage, Organization, Article, BreadcrumbList, WebSite), author signals, AI bot access, llms.txt. GEO: About/Contact/Privacy links, author bio and credentials, editorial review, featured snippet paragraphs, TL;DR sections, statistics, authority external links, attribution phrases, content depth (800+ words), comparison content, intent-matching titles, FAQ sections, question subheadings. Performance: LCP, CLS, TBT, FCP, TTFB, TTI via PageSpeed Insights.
Does VektorAI provide AI-powered fix suggestions?
▶
Yes. For applicable issues, VektorAI generates contextual fix suggestions built from your page's actual content. This includes rewritten meta descriptions and title tags, complete JSON-LD schema blocks (FAQPage, Organization, Article), Open Graph rewrites, featured snippet paragraphs, TL;DR sections, FAQ entries, question-style headings, and author biography templates. Every suggestion uses your page's own title, headings, and content as context — not a generic template. AI fix suggestions are available when you sign in and access your saved audit history.
