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.

FAQ

Knowledge Base questions, answered

What is the best knowledge base software for customer support teams?+

AI models do not converge on a single answer. Across 19 discovery prompts, no brand achieved dominant shortlist status. When forced to compare, Seismic Knowledge scores highest (52) in head-to-head evaluations, followed by Archbee (41) and Document360 (38).

Which knowledge base platform do AI models cite most often?+

No platform appears consistently. The category shows a 0% shortlist coverage rate, meaning AI recommendations vary widely by prompt. Seismic Knowledge, Archbee, and Document360 appear in the most comparison queries (6, 6, and 4 respectively), but none dominate discovery-stage answers.

How does Zendesk perform in knowledge base AI citations?+

Zendesk Support Suite scores 72 in featured contexts but drops to 30 in direct knowledge base evaluations. AI models cite it more often for broader help desk use cases than for purpose-built KB functionality.

Are there any rising knowledge base brands in AI citations?+

Seismic Knowledge gained 16 points between March and April 2026, the largest delta in the category. However, only two months of audit data exist, so it is too early to call this a durable trend.

What is the average AI citation score for knowledge base software?+

The category average is 61 across 27 tracked brands. The median evaluation score is 34, meaning most tools cluster below the mean. Seismic Knowledge (52) is the only platform scoring meaningfully above both benchmarks in head-to-head comparisons.
