What DataJelly Is
DataJelly is an automated server-side rendering and AI SEO platform that converts JavaScript-heavy websites into fully rendered, bot-ingestible HTML snapshots — without requiring SSR migrations, rewrites, or code changes.
Snapshots are the foundation of how DataJelly makes SPAs visible, indexable, and AI-ready.
Without DataJelly vs With DataJelly
Without DataJelly
Bots see blank or partially rendered JavaScript pages
- ✗Empty root div
- ✗Late-loading metadata
- ✗Missing structured data
- ✗Unrendered product or content sections
With DataJelly
Bots see the fully rendered version of your page
- Final HTML + DOM
- All metadata resolved
- Canonical tags available
- Structured data extracted
- Screenshots + health metrics collected
The SEO Problem With SPAs
JavaScript-heavy Single Page Applications don't reliably render for search bots or AI crawlers. If your content loads only after hydration:
- Google may index an incomplete document
- ChatGPT and Perplexity may ingest an empty page
- Structured data may never be seen
- Metadata may be missed entirely
- AI engines cannot summarize or rank your content
Snapshots solve this automatically.
DataJelly prerenders every route in a real browser and serves clean, bot-friendly HTML instantly — no code changes, no config, fully automated.
How Snapshots Work
A deterministic, pipeline-based rendering system
1.Route Capture
DataJelly scans your domain and automatically discovers all public SPA routes. Links, navigation patterns, and sitemap hints are used to ensure coverage.
2.Headless Rendering
Each route is loaded in a real Chromium browser. JavaScript executes fully, content hydrates, dynamic elements resolve, and the final DOM stabilizes. This guarantees render accuracy.
3.Clean Metadata Extraction
DataJelly extracts <title>, meta descriptions, OpenGraph tags, canonical URLs, JSON-LD structured data, robots directives, and HTTP headers. Every metadata layer is normalized for SEO and AI ingestion.
4.Snapshot Storage
Snapshots and structured artifacts are stored in the DataJelly edge cache and durable storage, ready to be served instantly to bots.
5.Edge Delivery
When a bot visits, bot detection classifies the request, the bot is routed to the correct snapshot, and final HTML is returned immediately. Human users still see your SPA normally.
This ensures fast indexing and AI-ready visibility.
What's Inside a Snapshot
Structured Data Collected Per Route
Snapshots capture everything AI bots need to understand your content.
Why Snapshots Matter
Snapshots are more than pre-rendered HTML — they power your entire visibility stack.
Developers
Debug SEO issues without changing app code. See exactly what bots (and AI crawlers) ingest.
Marketers
Ensure every campaign page is indexable, traceable, and tracked. No surprises in search rankings.
SEO Teams
Better crawling. Higher rankings. Complete metadata visibility.
Ops & Engineering
Snapshots double as monitoring tools — catching errors and regressions automatically.
Unique Benefits of DataJelly Snapshots
Zero Code Changes
Works with any SPA or frontend stack (React, Vue, Angular, Lovable, V0, etc.).
Edge Caching
Snapshots are stored at the edge for near-instant bot delivery.
Automated Refresh
TTL-based refresh ensures snapshots stay fresh without manual work.
Dual Purpose
Snapshots serve both SEO indexing and security scanning pipelines.
Monitoring Built-In
Alerts when pages break, regress, or degrade.
Common Snapshot Issues We Detect
Snapshots allow you to find — and fix — every visibility blocker.
Snapshots and AI SEO
The foundation of AI visibility.
AI crawlers such as ChatGPT, Perplexity, and Google AI Overviews require:
SPAs cannot provide this reliably.
Snapshots ensure AI systems ingest the final page structure, all content above and below the fold, your real metadata, and clean semantic signals.
Snapshots make your site eligible for inclusion in:
- ChatGPT Search
- Google AI Overviews
- Perplexity citations
- Bing Copilot answers
- AI-powered answer engines everywhere
Who Snapshots Are For
Frequently Asked Questions
1. What exactly is a snapshot?
A snapshot is a fully rendered version of your SPA route, captured in a real Chromium browser. It includes complete HTML + DOM, resolved metadata, OpenGraph + structured data, timing metrics, console logs, and a screenshot of the rendered page. This is the version bots and AI crawlers receive.
2. Why do SPAs need snapshots?
SPAs rely on JavaScript to load their content. Search bots and AI crawlers often do not run JavaScript reliably, meaning they only see an empty <div id="root">, missing metadata, no structured data, and no content for indexing. Snapshots ensure bots receive a complete, ready-to-index HTML document.
3. Do snapshots change how humans see my website?
No. Humans still receive your normal SPA. Only bots (Google, ChatGPTBot, PerplexityBot, etc.) receive the snapshot version. Snapshots do not affect your frontend code, UX, or performance.
4. How often are snapshots refreshed?
Snapshots refresh automatically based on TTL schedules, route-specific freshness requirements, content updates, and detected health issues. You never have to rebuild or manually trigger snapshot updates.
5. What happens if a snapshot breaks?
DataJelly's monitoring detects JavaScript errors, missing metadata, rendering failures, broken links, and slow-loading routes. You receive alerts, and DataJelly retries or refreshes snapshots to keep them healthy.
6. Are snapshots the same as server-side rendering (SSR)?
Functionally: yes — for bots. Snapshots give bots the same benefits as SSR: full HTML, rendered content, and stable metadata. But unlike SSR frameworks (Next.js, Nuxt), there's no rebuild, no migration, no code changes, and no architectural overhaul. Snapshots are automated SSR, delivered at the edge.
7. Do snapshots help with AI SEO and GEO?
Yes — snapshots are required for AI SEO. AI crawlers need deterministic HTML, immediate content, clean metadata, structured data, and predictable routing. SPAs cannot deliver this reliably. Snapshots make your site AI-ingestible, improving visibility in ChatGPT Search, Perplexity, Claude, Bing Copilot, and Google AI Overviews.
8. How does DataJelly capture dynamic or lazy-loaded content?
We render your page in a real browser environment: JavaScript executes, dynamic elements resolve, lazy-loaded content is captured, hydration completes, and the final DOM stabilizes. This ensures 100% fidelity to what a human would see.
9. Can snapshots capture authenticated pages?
By default, DataJelly captures public-facing routes only. Authenticated or gated content can be configured via a controlled rendering workflow if needed.
10. Do snapshots support structured data like JSON-LD?
Yes — DataJelly extracts and normalizes structured data from JSON-LD, Microdata, OpenGraph, and Twitter Cards. Structured data becomes part of the snapshot, helping both SEO and AI understanding.
11. What frameworks are supported?
All modern SPA and front-end frameworks: Lovable, Bolt.dev, V0, React, Vue, Angular, Svelte, Vite, and Astro (client-heavy routes). Snapshots work with anything that renders in a browser.
12. Does this replace prerender.io or traditional prerendering services?
Yes. DataJelly provides higher fidelity rendering, cleaner metadata extraction, built-in monitoring, AI crawler routing, GEO optimization, and edge-level delivery. It is the next-generation version of prerendering — built for 2026+ AI search.
