What AI-built sites get wrong.
Every public scan on Vettd contributes to this dataset. The table below shows how often each of our 82 checks fails across 1,042 scanned sites, re-aggregated hourly. Use it to see what to look for before you ship.
Top 5 most-missed
Without error tracking, users hit bugs and you never know — Sentry, LogRocket, or similar
Prevents your site from being embedded in iframes on malicious sites (clickjacking)
Without traffic analytics you have no idea who visits your site, where they come from, or what they do — error tracking alone is not enough
Most AI crawlers (GPTBot, ClaudeBot, etc.) do NOT execute JavaScript. If your headlines, body copy, or core content only appear after hydration, AI engines see an empty page and can't cite you.
AI engines lean on Schema.org types like Article, Product, Organization, FAQPage to extract clean facts. A site without these gets paraphrased less accurately and cited less often.
