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

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.

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.

Subcategory · AI Citation Index

AI Coding

AI coding is fragmented. Cursor surfaces in 100% of buyer queries across all four engines, Codeium in 91%, and Default in 83%, but no brand dominates by a margin that matters — the top three trade visibility within 17 points. GitLab and Tabnine hold the middle of the shortlist with four-engine presence but half the mention rate of the leaders. Windsurf appears on three engines but misses one entirely, making its footprint fragile. The category has no consensus pick yet; it is a three-way tie at the top with a long tail of specialists.

Buyer questions

What AI cites for top AI Coding questions

Every query in this category is discovery-stage exploration. Buyers ask AI for the best coding assistant by company size, role, or deployment context — 'best AI coding software for early-stage startups', 'which AI coding software works best for independent contractors', 'best AI coding software for large enterprises'. No head-to-head comparisons, no pricing or trust questions; the entire query set is top-of-funnel shortlist building.
