The Problem

Google Can't See Your JavaScript Pages

Here's what happens every time a bot visits your site

🤖

Bot visits your page

A search engine bot opens your URL

📄

Server sends an empty page

Instead of content, it sends instructions: "run this JavaScript code to build the page"

⏳

Code needs to run

Your browser would run the code — but the bot can’t or won’t wait

❌

Bot sees nothing

It records a blank page and moves on

✕

Your page is invisible in search results

See what crawlers actually receive — free tool.

✕

Crawl budget wasted

Bots spend your crawl budget waiting for JS to render instead of indexing content

✕

Pages skipped entirely

Complex SPAs/PWAs often return empty HTML shells that bots can't parse

✕

No rich snippets

Without rendered meta-tags & structured data, you get plain blue links at best

✕

Broken link previews

Shared links on Slack, WhatsApp, Facebook show blank cards — zero engagement

FAQ

Still on the Fence?

“Will this affect what my users see?”

No. Prerendering is a transparent proxy. Human visitors get your normal site. Only bots receive the pre-rendered static HTML.

“Is this considered cloaking by Google?”

No. Google officially recommends pre-rendering for JavaScript sites. You're serving the same content — just faster and pre-rendered.

“What if it breaks my site?”

Zero risk. It's middleware that only activates for bot traffic. Your app code doesn't change. Remove it anytime with no side effects.

“We already have SSR set up.”

Prerendering still helps — cached static delivery from co-located servers is faster than SSR rendering on every request. It also improves link previews and AI bot access.

“How do I know it's working?”

Real-time analytics dashboard shows every crawl, cache hit, status code, and response time. You can also use our prerender checker to confirm the x-prerender-id header is present for bot requests.

“What about data freshness?”

Configurable TTL from 2 hours to 31 days. Auto-recache refreshes pages automatically on expiration. Instant purge anytime for major updates.
