Google’s New Talk on Website Rendering
In a recent Search Central Lightning Talk, Martin Splitt from Google discussed how rendering affects website performance and SEO. He explained how developers can make their websites easier for search engines to understand.
Splitt also addressed concerns about using too much JavaScript. He shared ways to balance dynamic content with better search visibility.
What Is Website Rendering?
Rendering is creating a complete web page from data and templates. Splitt explained that modern websites use templates to build pages with the same structure but different content, such as product listings or blog posts.
Splitt described three main types of rendering:
- Pre-Rendering (Static Site Generation)
- Server-Side Rendering (SSR)
- Client-Side Rendering (CSR)
Each method impacts how search engines crawl and index a site.

1. Pre-Rendering: Simple but Limited
Pre-rendering generates web pages before users visit them. Tools like Jekyll and Hugo help developers automate this process.
Pros:
- Minimal server load
- High security
- Reliable performance
Cons:
- Requires updates for new content
- Limited user interactions
Splitt explained that pre-rendering works well for static websites but may not suit sites needing real-time updates.
2. Server-Side Rendering (SSR): Flexible but Resource-Intensive
SSR generates web pages on the server when users request them. This allows for personalized content, like user dashboards or comments.
Pros:
- Supports dynamic content
- Handles user interactions
Cons:
- Needs more server resources
- Slower load times
Splitt suggested using caching to reduce server strain and improve speed.

3. Client-Side Rendering (CSR): Interactive but Risky
CSR uses JavaScript to load content in the user’s browser. It offers a smooth, app-like experience.
Pros:
- Interactive and seamless
- Works offline with PWAs
Cons:
- Depends on the user devices
- SEO challenges if JavaScript fails
Splitt recommended a hybrid approach called “hydration,” which combines server-side and client-side rendering for better SEO.
Choosing the Right Rendering Method
Splitt said there’s no single solution for all websites. Developers should choose based on their site’s purpose, update frequency, and user interactions.
Factors to consider:
- How often the content changes
- What kind of user interactions are needed
- Available resources for maintenance
Limiting JavaScript for Better SEO
Too much JavaScript can cause SEO problems, especially with AI crawlers like GPTBot. Splitt suggested limiting JavaScript to ensure that search engines can see essential content.
Recommendations:
- Use SSR or pre-rendering for key content
- Apply progressive enhancement to improve usability
