SPA SEO Audit: Stop Letting Crawlers See Empty Shells
Single-page apps (React, Vue, Svelte) confuse most SEO tools. Here is exactly how to audit a SPA so Google + ChatGPT actually see your content.
Single-page apps render in JavaScript. The classic SEO tools (Screaming Frog default, Ahrefs Site Audit, Moz crawl) parse the initial HTML payload and find a near-empty `<div id="root">`. They then report your content is missing, your H1 is missing, your meta is missing - when actually all of it loads after JS executes. If you are auditing a SPA the same way you would a WordPress blog, you are auditing the empty shell, not your site.
A real SPA audit needs a real browser. Pinealizer renders every page with full Playwright + JavaScript execution, then audits what the rendered DOM actually looks like - same as Googlebot, GPTBot, ClaudeBot, and PerplexityBot do. 938 checks across 26 disciplines, including SPA-specific ones: hydration cloak detection, prerender match validation, route-level metadata leakage, client-side title swaps, and lazy-load gating of critical content.

FAQ
Frequently Asked
Yes if you enable JS rendering, but it is single-machine, slow, and does not simulate AI bot user agents. Pinealizer runs cloud Playwright with bot UA swaps for GPTBot, ClaudeBot, PerplexityBot.
Google renders most React reliably now, but with a delay (the Web Rendering Service queues JS pages). Pre-rendering or SSR removes the delay. Pinealizer flags pages that depend on JS for critical content above the fold.
Common SPA bug: server HTML and client React tree differ, content flickers, schema gets stripped on rehydrate. Pinealizer compares rendered DOM vs cached prerender to flag mismatches.
No. Pinealizer simulates 9 AI search engines plus traditional bots in one scan. You see Google, ChatGPT, Perplexity, Claude, Gemini, Copilot, Meta AI, Grok, and Google AI Overviews readiness side by side.
