AI-search visibility is how likely an AI answer engine is to find, understand, and cite your app when someone asks it a relevant question. As users move from typing queries into Google to asking ChatGPT, Claude, and Perplexity, this is becoming as important as classic SEO — sometimes called answer engine optimization (AEO).
Why AI-built apps are especially at risk
Most AI builders ship a JavaScript SPA whose initial HTML is nearly empty. Many AI crawlers don't run JavaScript, so they see a blank shell — the app is effectively invisible to the exact channel where discovery is growing fastest.
What makes an app AI-visible
- Server-readable content — title, meta, and key copy present without JavaScript.
- An llms.txt brief — a plain-text summary of what you do, who it's for, pricing, and key pages.
- Clean indexing — robots.txt and sitemap.xml so crawlers can enumerate your pages.
- Citations — being linked and mentioned where AI training and retrieval look.
How Actuant helps
The audit's AI-search visibility check (weight 8) verifies your llms.txt, a companion check (weight 4) confirms robots.txt doesn't block GPTBot and friends, and the Portfolio plan's monitor_ai_visibility tool tracks when AI answers actually start citing your app.
