# DataJelly | Prerendering for JavaScript SEO (Bots See Your Real Site)
> DataJelly renders JavaScript pages for bots at the edge—served as HTML for search crawlers and clean extracts for AI. Fix indexing and metadata without a rebuild.

---

## Make your website visible to Search and AI — not partial HTML.

DataJelly serves pre-rendered HTML to search crawlers and clean Markdown to AI — without changing your app.

Most JavaScript apps send <5KB of HTML to crawlers. Your real content loads after JavaScript.

Without DataJelly

HTML: 3 KB

Text: "Loading..."

Indexable: ✗

With DataJelly

HTML: 120 KB

Text: Full content

Indexable: ✓

No rebuild. No framework changes. Works with any JS stack.

The hard truth about modern JavaScript sites

## Your site works perfectly.
Bots miss your main content.

When bots can't extract your content, you don't get indexed, cited, or recommended — competitors do.

Typical JS App

~12%

of content extractable by bots

With DataJelly

100%

of core content extractable
## What this is costing you today
### AI Visibility Losses

- ✕ChatGPT and Perplexity skip pages they can't extract
- ✕Your competitors with crawlable content get recommended instead
- ✕AI answers that should include you — don't
### Search Visibility Losses

- ✕Google indexes a skeleton, not your actual content
- ✕New pages take weeks or months to get indexed — if ever
- ✕Rankings plateau while competitors climb
## The Fix: One layer. Every bot. Right format.

DataJelly sits between your site and the bots. They each get exactly what they need.
