Making JS Visible: A JavaScript SEO & Rendering Strategy
Client: A Single Page Application (SPA) SaaS platform built on React.
Challenges We Faced
The client’s modern React website was sleek, but invisible to search engines because it relied entirely on client-side rendering:
Blank Pages
A negative, 2-year-old news article was “stuck” at position #3 for their brand name.
“Soft 404s”
GSC reported thousands of soft 404s because the content wasn’t rendering.
No Content Indexed
Their rich, valuable content was hidden behind JS scripts.
low Render Time
Even when Google did render it, the page speed was terrible.
Fix Your JavaScript SEO

Our Approach – How We Solved These Challenges
JavaScript SEO & Rendering
We implemented Dynamic Rendering (using a tool like Prerender.io) to serve a static HTML version of the page to Googlebot while serving the JS version to users.
Comprehensive Crawl Audit
We used Screaming Frog (configured to render JS) to identify all the resources (CSS/JS files) that were accidentally blocked in robots.txt.
Mobile-First Crawl Optimization
We ensured the static HTML version served to mobile bots was 100% identical in content to the desktop version.
Technical SEO
We fixed the internal linking, changing onclick events (which bots can’t follow) to standard <a href> links.

Advice for Marketers & Brand Owners
- Google struggles with JavaScript. If you have a React, Angular, or Vue site, you must consider Dynamic Rendering or Server-Side Rendering (SSR).
- Don’t block your resources. Ensure your CSS and JS files are not blocked in robots.txt. Google needs them to render the page.
- Use real links. Googlebot doesn’t click buttons. Use standard <a href> tags for navigation.
- Test your rendering. Use the “URL Inspection” tool in GSC to see exactly what Google sees (or doesn’t see).
Extra Factors That Made It Work
- Dynamic Rendering was the silver bullet. It instantly made the site readable to search engines.
- Changing the navigation links to standard HTML allowed the bots to finally crawl the site structure.
- Unblocking resources in robots.txt allowed Google to understand the page layout.
