How to audit a website for AI citation (2026 guide + free checklist)
A practical review of crawlability, clear content and supported structured data. These readiness observations do not prove that an AI service will cite a page.
Frequently asked questions
Is AI citation a real ranking factor or a marketing buzzword?
Both. Multiple AI engines (Perplexity, Google AI Overviews, Bing Copilot) openly publish citation lists in their answer flows. Whether to call it 'ranking' is semantic - what matters is whether your URL appears as a cited source when someone asks an AI engine about your category.
Will Google penalise me for llms.txt?
llms.txt is an optional proposal. Google does not require a special AI file for Search inclusion. Its presence or absence is not evidence of a ranking or citation outcome.
Do I need BreadcrumbList on my homepage?
No. The homepage is the root - there is no parent. BreadcrumbList only applies to sub-pages (/services, /blog/post-slug, etc.).
What's the difference between this and a normal SEO audit?
Both review crawlability, indexability, useful content and coherent entity information. AuditHQ also distinguishes provider search-crawler controls from model-training preferences. No fixed percentage of overlap or citation outcome is established by this audit.
Should every page have all 9 signals?
No. Signals 1, 2, 5, 8 are site-level (robots.txt, llms.txt, semantic HTML, performance). Signals 3, 4, 6, 7, 9 are per-page and matter most on pages you actually want cited (homepage, key service pages, long-form articles, glossary entries).
