How Scrunch makes JavaScript‑heavy websites crawlable for AI bots

Scrunch’s Agent Experience Platform (AXP) makes JS‑heavy sites easy for AI crawlers to read by delivering a clean, AI‑optimized version of each page—without any JavaScript dependency. Human visitors see your normal site; AI agents receive server‑rendered HTML that’s compressed, structured, and mapped to your sources of truth.

How it works

Intercept AI traffic Your CDN (Akamai, Cloudflare, or Vercel) routes recognized AI user agents (e.g., ChatGPT‑User, PerplexityBot) to AXP.
Translate your content for AI AXP strips superfluous code and renders pages as bot‑friendly HTML. It adds structured summaries and context blocks, clarifies entities and claims, and removes or simplifies dynamic components so agents can parse key information immediately.
Serve the right version to the right visitor AI agents get the optimized version; humans get your standard site. Search indexing bots (Googlebot, Bingbot) are not routed to AXP, so traditional SEO and rankings remain unaffected.

Example

When you enable AXP, AI traffic flowing to an existing URL is routed to the AXP origin. AXP responds with clean, pre‑rendered HTML that surfaces critical copy and clarifies terms. This keeps important content visible to AI agents and improves brand mentions and citations in AI results.

Implementation notes

No code changes required AXP runs at the CDN level, so you don’t have to modify your framework or rewrite components. It works in real time alongside your current website.
Validating the setup Use Scrunch’s auditing to verify that AI agents are accessing your pages successfully. Audits flag JavaScript rendering issues and confirm that AXP is delivering clean HTML to AI bots. After enabling AXP, monitor changes in brand presence and citations across AI platforms using Scrunch.

AXP vs. publishing AI‑friendly content in your CMS

Publishing “AI‑friendly” copy directly in your CMS can help, but it often duplicates content, increases maintenance, and still leaves JavaScript rendering issues unsolved. AXP offers a parallel, automated layer purpose‑built for AI:

Works without code edits and preserves your human UX.
Operates at the CDN, so it consistently intercepts AI agents across your entire site (including SPAs and dynamic pages).
Applies page‑ and template‑level enhancements—structured summaries, clarified definitions, and simplified components—without altering source templates.
Reduces content bloat for LLMs (AXP outputs are often orders of magnitude fewer tokens than human pages).
Maps content to your approved sources of truth and existing URLs, minimizing drift and rework in the CMS.

You can still refine on‑page copy in the CMS for clarity; AXP ensures AI agents actually receive and understand it.

Flexibility across content types

AXP adapts to different page types without changing your codebase:

Documentation and how‑tos: Surfaces steps, definitions, and key entities in structured blocks.
Blogs and resources: Highlights summaries, claims, and citations so agents extract context quickly.
Product and pricing pages: Simplifies interactive components and tables while preserving the core value props and details.

You can apply approved enhancements at the page or template level, and AXP will serve AI‑ready versions automatically.

Detecting JavaScript and rendering issues that block AI crawlers

Scrunch’s auditing identifies whether AI agents are successfully accessing your content and pinpoints JavaScript rendering problems. It confirms whether AXP is serving clean, server‑rendered HTML to AI bots and helps you validate improvements after changes. Scrunch also uses multiple methodologies—browser automation and official platform APIs—to collect prompt and response data from leading AI platforms, ensuring your view of AI visibility reflects real agent behavior.

How Scrunch’s AI site audit differs from a traditional SEO crawl

Purpose: An AI site audit checks real‑time retrieval for AI agents (e.g., ChatGPT, Perplexity) and validates AXP delivery. A traditional SEO crawl focuses on search engine indexation (e.g., Googlebot) and technical SEO.
Output: AI audits emphasize parse‑ability for LLMs—clean HTML, structured summaries, clarified entities, and simplified dynamic content—rather than canonicalization, sitemaps, or link graphs.
Scope: AI audits verify routing logic at the CDN and whether agents are receiving the optimized experience, while SEO crawls inspect the human‑facing site for ranking factors.
