<b>JS sites: the render queue is your real indexing bottleneck</b>

Google indexes JS in two waves — crawl HTML, then render later. That second queue is where SPAs vanish.

How to diagnose:
— URL Inspection → 'View crawled page' → check if your content is in the rendered HTML or only after JS
— 'Test Live URL' shows the rendered DOM Google sees; if your links/text are missing there, they don't exist for indexing
— Compare raw view-source vs rendered

What the tool does well:
— Renders with Google's own engine, no guesswork about polyfills

Where it falls short:
— Live test ≠ the deferred render queue's real-world delay (can be days/weeks on big sites)
— One URL at a time

Pros: definitive 'does Google see my JS content' answer.
Cons: doesn't reveal render-queue latency, per-URL only.

Best for: React/Vue/Next sites debugging missing-content indexing.

Fix path: SSR or prerender critical content into the initial HTML. Don't rely on the render wave for money pages.
