Understanding Google’s AI Crawler and Rendering
Google’s AI crawler and rendering process have been a topic of discussion among developers and marketers. In a recent interview, Google Developer Advocate Martin Splitt shared key information about JavaScript rendering, server-side vs. client-side rendering, and structured data. The talk aimed to clear up common SEO confusion and offer practical tips for developers and marketers working with Google’s changing search systems.
Google’s AI Crawler and JavaScript Rendering
When asked how AI systems handle JavaScript content, Splitt revealed that Google’s AI crawler processes JavaScript well through a shared service. He explained that the AI crawler uses Web Rendering Service (WRS), which is also used by Googlebot. This gives Google’s AI tools an edge over competitors that have trouble with JavaScript. Splitt noted that rendering usually happens within minutes, with the 99th percentile being within minutes, suggesting that long delays are rare and might be due to measurement errors.
Server-Side vs. Client-Side Rendering: Which is Better?
The debate between server-side rendering (SSR) and client-side rendering (CSR) was also discussed. Instead of saying one is always better, Splitt stressed that the right choice depends on what your website does. For websites that are primarily informational, SSR or pre-rendering static HTML is recommended. However, for interactive tools like CAD programs or video editors, CSR is more suitable. Splitt emphasized that it’s not a matter of one being better than the other, but rather using the right tool for the job.
Structured Data’s Role in AI Understanding
The interview also touched on structured data, which is becoming more important as AI systems grow in search. Splitt confirmed that structured data helps Google’s AI understand content better, but clarified that it does not directly impact rankings. He stated that structured data provides more information and confidence in the information, making it essential for SEO professionals.
Key Takeaways
Here are the key things we learned from the interview:
- Google’s rendering usually happens within minutes, reducing the disadvantage of JavaScript-heavy sites.
- Non-Google AI tools may still have trouble with JavaScript, making SSR crucial for visibility across all AI systems.
- Use SSR for content sites and CSR for interactive tools, as each has its own strengths.
- Structured data helps Google understand content better, but is not a direct ranking factor.
Conclusion
In conclusion, understanding Google’s AI crawler and rendering process is essential for developers and marketers. By using the right rendering method for their website and incorporating structured data, they can improve their content’s visibility and user experience. As AI continues to change search technology, focusing on basic principles like creating great content and thinking about user needs will become increasingly important. As Splitt advised, "Think about your users, figure out what is your business goal, how to make users happy, and then just create great content."
