Questions people ask
What is Answer Engine Optimization (AEO)?
AEO is optimizing a website so it gets cited in answers from AI search engines like ChatGPT, Perplexity, and Gemini, rather than aiming for search ranking positions as classic SEO does. Key factors are structured data, clear content, and verifiable facts.
How does the Yaystack audit work?
You enter a URL and Yaystack checks the page against more than 60 factors in six categories. About 55-60% of the check is deterministic technical checks, and 40-45% is AI-based analysis at temperature 0, producing a 0-100 score with prioritized recommendations.
Which AI search engines does Yaystack cover?
Yaystack evaluates visibility for ChatGPT, Perplexity, Gemini, Claude, and Copilot, since the signals it checks (structured data, E-E-A-T, citability) apply across these answer engines.
What does Yaystack cost?
The first audit is free and requires no signup. The Standard plan costs CHF 25 per month for 200 credits, all findings, history comparison, and competitor analysis, with no minimum contract.
How reliable is the AEO score?
The score is shown with a range, such as '67 ± 10', reflecting model variance from a single AI analysis at temperature 0; differences under 5 points between two analyses are generally statistical noise.
