Google Bot Simulator & SSR Tester
See your site exactly as Google Bot sees it. Check for SSR, missing tags, and JS rendering issues.
What is Google Bot Simulator & Why it Matters?
In modern JavaScript websites (React, Vue, Next.js, etc.), the biggest SEO risk is Google Bot failing to see your content. This tool helps you detect how your site is perceived by Google, indexing issues, and rendering problems.
01How Google Bot Works?
Google Bot crawls your site in two phases: First, it reads the Raw HTML response (Crawl), and later, if resources exist, it executes JavaScript (Render). However, the Render phase is costly and doesn't always happen immediately or perfectly. For SEO success, it's critical that your content is visible to the bot during the initial 'Crawl' phase without needing 'Render' (SSR - Server Side Rendering).
02CSR vs SSR: The SEO Battle
Client Side Rendering (CSR/SPA): Content is built in the browser with JS. Google Bot may see a blank page initially. This is a major SEO risk.
Server Side Rendering (SSR): Content is generated on the server and served instantly as HTML. Google Bot sees 100% of the content. This is why Next.js and Headless WordPress architectures are perfect for SEO.

Frequently Asked Questions
Can Google Bot execute JavaScript (JS)?
Yes, but this happens in the 'Render' phase and consumes your Crawl Budget. Also, it may not execute every JS library or modern code perfectly. The safest method is to use SSR.
What is the difference between this tool and Fetch as Google?
The 'Fetch' tool in Search Console shows the rendered version of your site. This tool shows the 'Unrendered' raw HTML version, which is the source of 90% of indexing issues.
I see a blank page, what should I do?
If your site appears empty in this tool, it means your site is running entirely on CSR (Client Side Rendering). You should urgently switch to an SSR (Server Side Rendering) or Prerendering solution.
