Server-Side vs. Client-Side Rendering: What Google Recommends
In a recent enlightening interview with Kenichi Suzuki from Faber Company Inc., Google Developer Advocate Martin Splitt shed light on the ongoing debates surrounding JavaScript rendering, specifically focusing on server-side rendering (SSR) versus client-side rendering (CSR). As we traverse the ever-evolving landscape of SEO, understanding these distinctions is crucial for developers and marketers alike.
Google’s AI Crawler & JavaScript Rendering
When the conversation shifted to how Google’s AI systems manage JavaScript content, Splitt shared invaluable insights. He revealed that Google’s AI crawler (utilized by Gemini) adeptly processes JavaScript through a centralized service known as the Web Rendering Service (WRS).
“We don’t share what Googlebot sees for web search, but Google’s AI crawler that Gemini uses also renders. It uses WRS, which means it’s backed by the same resources as Googlebot.”
This technology empowers Google’s AI tools with capabilities that can surpass competitors struggling with JavaScript rendering. While some studies have suggested that rendering could take weeks, Splitt reassured us that, more often than not, this process typically happens within minutes.
“The 99th percentile is within minutes,” he remarked, indicating that long rendering delays are an anomaly, potentially due to measurement errors.
Server-Side vs. Client-Side Rendering: Which is Better?
One of the most debated topics in web development is the choice between SSR and CSR. Instead of proclaiming one method as superior, Splitt emphasized that the optimal choice is contingent on your website’s specific functionalities.
“If you have a classical website that primarily presents information, requiring JavaScript can be a drawback. It may slow down the experience and drain battery life on devices.”
For websites aimed primarily at delivering content, SSR is often the recommended strategy. On the flip side, for more interactive applications—like CAD programs or video editing tools—CSR may come into play.
“It’s not one or the other; it’s about choosing the right tool for the job. Do you need a hammer or a screwdriver? That depends on your task at hand.”

Structured Data’s Role in AI Understanding
As the conversation progressed, the significance of structured data became apparent, especially as AI systems continue to evolve in search. When questioned about whether structured data enhances Google’s understanding of content—akin to Microsoft’s claims regarding Bing—Splitt responded affirmatively.
“Structured data provides us with richer information, increasing our confidence in what we see. It’s essential for clarity.”
However, he made an important distinction: while structured data indeed enriches contextual understanding, it does not directly influence search rankings.
“Structured data adds context, but it does not directly impact rankings. SEO professionals should be aware of this nuance.”
What This Means
Here are some critical takeaways from Splitt’s interview:
- Fast Rendering: Google’s rendering typically occurs within minutes, alleviating prior concerns about JavaScript-heavy sites.
- SSR for Visibility: Non-Google AI tools may struggle with JavaScript, making SSR increasingly vital for broader visibility.
- Tailored Approaches: Utilize SSR for content-focused websites and CSR for interactive applications—don’t adopt a one-size-fits-all method.
- Value of Structured Data: Though not a direct ranking factor, structured data helps Google interpret your content more effectively, which is crucial as AI gains importance in search.
In closing, Splitt offered timeless advice to SEO practitioners:
“Focus on your users. Identify your business goals, aim to enhance user experience, and, above all, create great content.”
As AI reshapes the search landscape, grasping these technical nuances becomes increasingly important for marketers seeking to optimize content for both users and evolving search algorithms.
