Why Pre-Rendering?

Modern Googlebot can render JavaScript, but with delay. AI crawlers can't render at all.

01

AI Crawlers Need Stable HTML

GPTBot, ClaudeBot, and PerplexityBot never execute JavaScript. They read raw HTML only — your React content is invisible to AI answers.

02

Google's Rendering Delays

Pages may wait hours or days in Google's rendering queue. Low-priority pages might never get rendered at all.

03

Content Remains Invisible

React, Vue, and Angular apps show empty shells to bots. Your most important content never gets indexed.

What Google Says

Direct quotes from Google's official documentation.

"Dynamic rendering was a workaround and not a long-term solution... Instead, we recommend that you use server-side rendering, static rendering, or hydration as a solution."
Google Search Central: Dynamic Rendering
"Server-side rendering or pre-rendering is still a great idea because it makes your website faster for users and crawlers."
JavaScript SEO Basics
"The page may stay on this queue for a few seconds, it may also stay longer."
On the Rendering Queue
"It creates additional complexity for your site setup. Debugging issues becomes more challenging."
Dynamic Rendering Caveats

Crawl Budget: The Invisible Limit

Google allocates limited time to crawl your site. Every slow response means fewer pages indexed.

Every Site Gets a Crawl Budget

Google allocates a fixed amount of time and resources to crawl each site. When that budget runs out, remaining pages wait for the next cycle — which could be days or weeks. Large sites with thousands of pages are hit hardest.

JavaScript Pages Drain Your Budget

A JS-rendered page can take 3-5 seconds to process. A pre-rendered page takes ~15ms. That means a single JavaScript page consumes the same budget as hundreds of cached pages. The math works against you at scale.

Faster Responses = More Pages Indexed

When crawlers get instant HTML responses, they index more of your site in every session. New products, updated listings, and fresh articles appear in search results faster — without waiting in a rendering queue.

AI Bots Don't Execute JavaScript

GPTBot, ClaudeBot, and PerplexityBot read raw HTML only. Your React content is invisible to AI answers.

If You're Not Renderable

  • Competitors featured in ChatGPT answers
  • Your products missing from AI recommendations
  • Zero visibility in AI-powered search

With EdgeComet

  • Product info appears in AI chat results
  • Articles seen by AI summarizers
  • Content contributes to AI-generated insights

Do You Have a Rendering Problem?

Answer these questions to find out if your site needs pre-rendering.

Does your content only appear after JavaScript loads?

If you're using React, Vue, Angular, or any SPA framework where content is rendered client-side, bots see an empty page. Use "View Page Source" (not DevTools) to see what crawlers see — if it's empty, you have a rendering problem.

Do new pages take days to appear in Google?

Google's rendering queue can delay indexing significantly. If your pages aren't appearing in search results within 24-48 hours after submission, JavaScript rendering delays are likely the cause.

Do AI tools rarely mention your site?

Try asking ChatGPT or Perplexity about topics your site covers. If competitors appear but you don't, AI crawlers likely can't read your JavaScript-rendered content. Pre-rendering makes your content AI-discoverable.
