Yaystack Audits Website Visibility in AI Search

Summary

Yaystack is a website-auditing product focused on Answer Engine Optimization (AEO), or improving the chance that a site is cited in AI-generated answers. Its page says the service evaluates visibility across ChatGPT, Perplexity, Gemini, Claude, and Copilot. A user can enter a URL for a free first audit without registering, with results promised in under 60 seconds. The audit checks more than 60 signals across six areas, including structured data, content clarity, E-E-A-T, entity authority, citation potential, conversational queries, and page performance through PageSpeed Insights. Yaystack produces a 0–100 score, prioritized findings, and recommendations, and its dashboard tracks score changes and open or resolved issues over time. Users can compare a domain with up to 10 competitors and export an audit as a PDF. The page lists a free plan with 30 one-time credits and one tracked URL, while the Standard plan costs CHF 25 per month and includes 200 monthly credits, up to 10 tracked URLs, and competitor analysis. Yaystack says roughly 55–60% of its checks are deterministic technical checks and 40–45% are interpretive AI analysis. It displays score uncertainty, such as “67 ± 10,” and explains that differences below five points are usually statistical noise. The site also presents claims about AI-search citation patterns, including that 73% of AI answers cite only the top three sources, without providing supporting evidence in the page text.
