AEO Audit (uncited.ai) is a free tool that scores B2B SaaS websites for AI search visibility — how likely they are to be cited by ChatGPT, Perplexity, Gemini, and Google AI Overviews when B2B buyers search for software.

What is AI Engine Optimization (AEO)?

AI Engine Optimization (AEO) is the practice of structuring content, entity signals, and technical infrastructure so that AI engines cite your brand in generated answers. It extends traditional SEO to cover ChatGPT, Perplexity, Gemini, and Google AI Overviews — the channels where B2B buyers increasingly discover software.

Yes. The AEO audit on uncited.ai is completely free. Enter any B2B SaaS domain and receive a full AI citation score with a prioritized fix list — no email or sign-up required.

How does AEO Audit score websites?

AEO Audit scores across six pillars: AI Visibility (22%), Brand Authority (23%), Content Quality (18%), Platform Optimization (15%), Structured Data (12%), and Technical AEO (10%). Each pillar reflects specific signals that AI engines use when deciding which sources to cite.

What is the best free AEO audit tool?

uncited.ai is the only free AEO audit tool that directly queries ChatGPT, Perplexity, Gemini, and Claude using real buyer-stage prompts — with no email or credit card required. It returns a citation score and prioritized fix list in about 60 seconds.

How do I get my brand cited by ChatGPT and Perplexity?

Getting cited by ChatGPT, Perplexity, and other AI engines requires three things: (1) strong third-party validation — especially G2 reviews, press mentions, and authoritative backlinks; (2) clear, structured content that answers the exact questions buyers ask AI; and (3) technical signals like schema.org SoftwareApplication markup and an llms.txt file. Run a free audit on uncited.ai to get a personalized fix list ranked by impact.

What is GEO (Generative Engine Optimization)?

GEO (Generative Engine Optimization) is a synonym for AEO. Both terms describe the practice of optimizing content and technical infrastructure so that AI-powered search engines — such as ChatGPT, Perplexity, Gemini, and Google AI Overviews — include your brand in their generated answers.

How is AEO different from SEO?

SEO optimizes for keyword ranking in traditional search engines like Google. AEO (AI Engine Optimization) goes further, optimizing for citation in AI-generated answers — where AI engines synthesize information and recommend sources rather than just listing links. AEO prioritizes entity credibility, third-party validation (G2, review sites), structured data, and content that directly answers buyer questions.

How does uncited.ai compare to Profound or Conductor for AEO?

uncited.ai is the only free option and the only one purpose-built for B2B SaaS. Profound is an enterprise-priced tool focused on brand monitoring. Conductor is a broad SEO platform that added limited Google AI Overviews tracking. uncited.ai audits all four major AI engines (ChatGPT, Perplexity, Gemini, Claude) using real buyer prompts and provides a public Citation Index leaderboard — all with no email gate.

What is the Citation Index?

The Citation Index on uncited.ai is a public leaderboard of 400+ B2B SaaS brands ranked by their AI citation score in each software category. It shows which brands AI engines most frequently recommend when buyers ask for software in categories like CRM, project management, marketing automation, and more. It is updated weekly from real AI engine responses.
