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.

AI Chatbots

AI chatbot discovery is a duopoly with a long tail. handoff.ai and intercom.com together own the shortlist — handoff.ai shows up in 90% of buyer queries about AI chatbots, intercom.com in 87%, and both surface across all four engines. base.ai follows at 69%, then Tidio at 63%; the gap widens sharply after that. Evaluation is fragmented: Boost.ai wins every head-to-head comparison it appears in, Azure AI Language scores 76 across ten matchups, and Cognigy — visible on three engines — loses more head-to-heads than it wins despite showing up in 31% of discovery prompts. This is a consolidated category at the top of the shortlist and contested everywhere else.

Evaluation stage

Head-to-head

How often AI cites each brand across uniform category evaluation prompts · median 54/100

Boost.ai wins every head-to-head comparison across four matchups. Trello Bot scores 79 across five comparisons, Azure AI Language 76 across ten. Cognigy appears in eleven head-to-heads but loses more than it wins, scoring 62 against a category median of 54. Helpshift and Forethought each show up in over a dozen comparison queries and score near the median — neither wins decisively, but both get asked about frequently enough to matter in the evaluation stage.
