Definition & Overview

Client-Side Ghosting is a critical technical defect where web content rendered exclusively via client-side JavaScript (SPA frameworks) appears completely blank to lightweight RAG scrapers and AI bots.

Unlike full browser engines that execute complex JS bundles, many lightweight AI search crawlers only parse raw initial HTML. Unrendered SPA pages appear as empty "ghost" pages.

Analogy & Mental Model

Client-Side Ghosting is like submitting a invisible ink document that requires special UV light to read: if the reviewer lacks the light, they see a blank page.

Why Client-Side Ghosting Matters

Client-side ghosting causes AI search engines to ignore your content, destroying AI visibility even if your site looks perfect to human browser users.

Concrete Real-World Application

A React single-page app displaying a blank root `<div>` to PerplexityBot because the server does not pre-render HTML.

How Client-Side Ghosting Works

Occurs when AI crawlers fetch raw HTML before client JS bundles execute.

Core Components & Mechanisms

Raw HTML Inspection

Bots requesting initial page HTML without executing full headless browsers.

DOM Empty State Detection

Finding empty `<div id="root"></div>` tags lacking textual content.

Citation Omission

The AI model marking the page as low-value or blank, skipping citation extraction.

Client-Side Ghosting vs AI Crawler Logs

AI Crawler Logs track bot requests to your server, whereas Client-Side Ghosting occurs when JavaScript-rendered text is invisible to simple AI bots that do not execute client scripts.

Frequently Asked Questions

How do you fix Client-Side Ghosting for AEO?

Implement Server-Side Rendering (SSR), Static Site Generation (SSG), or dynamic pre-rendering (Next.js, Nuxt, Prerender.io) so initial HTML contains full page text.
