Browser view
~120KB
full DOM, all content
Bot fetch
3–7KB
empty body, script tags
Same URL. Different output. The bot indexes the 3–7KB version.
If your bot HTML is under ~10KB or visible text is under ~200 characters, the page is effectively empty. It returns a 200 status — everything looks fine in monitoring — but the content isn't there.
This is the single most common SEO failure we diagnose on Vite apps.
## What's Actually Happening
Vite produces minimal initial HTML. This is by design — it's optimized for client-side speed, not bot readability:

All content is created *after* JavaScript runs. The initial HTML contains zero meaningful text.
Bots often:
- Don't execute JavaScript at all
- Time out before hydration completes
- Snapshot the page early, before content loads
