Understanding Google's Take on SEO Network Requests: Can Too Many Network Requests Cause Issue For Google Search & SEO
The SEO community is buzzing with discussions surrounding Google's recent clarification about network requests and their impact on search rankings. As always, Google's SEO guidelines are the stuff of legends—technical, nuanced, and often leaving us with more questions than answers. But hey, that's what makes it fun, right?
Recently, the Search Relations team at Google dropped some knowledge bombs about how network requests factor into crawling, indexing, and overall site performance. Spoiler alert: It's not as straightforward as you might think.
This article unpacks Google's latest clarification, explores the role of network requests in SEO, and offers practical strategies to keep your site firing on all cylinders while playing nice with Google's expectations.
The Context: Google's Response to Network Requests During Crawling
Breaking Down Google's Clarification on Network Requests
With the SEO community rife with theories, Google's Search Relations team stepped in to set the record straight: network requests, in and of themselves, are not direct ranking factors. Wait, what? Yes, you heard that right. Rankings don't hinge on the number, sequence, or type of requests Googlebot encounters during a crawl.
Instead, Google emphasized its commitment to user experience and performance metrics. While network requests may not directly affect rankings, they do impact factors like page speed, Core Web Vitals (CWV), and rendering capabilities—all of which indirectly influence your site's SEO mojo.
What Are Network Requests in SEO?
Network requests refer to the actions initiated when a browser or bot interacts with a website. When a page loads, the browser sends out multiple requests to fetch all the resources needed to render it fully. These resources can include:
From an SEO standpoint, ensuring these requests are fast, error-free, and optimized is critical for performance. Let’s explore why.
The Relationship Between Network Requests and SEO Performance
While network requests do not directly affect rankings, the way they interact with Googlebot and users' browsers can significantly impact other factors that influence SEO, such as:
1. Crawl Efficiency and Crawl Budget
Googlebot operates with a finite crawl budget for every site. This budget dictates how many pages and assets Googlebot will crawl within a specific timeframe. Unnecessary or excessive network requests can waste this budget, leaving critical pages uncrawled or assets unindexed.
Best Practices to Optimize Crawl Efficiency:
2. Page Speed and Core Web Vitals
Google uses page speed and Core Web Vitals (CWV) as ranking factors. High latency or bloated network requests can slow down load times and harm CWV metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
How to Improve Performance:
3. Mobile-First Indexing
Google has fully transitioned to mobile-first indexing, meaning it evaluates the mobile version of your site for indexing and ranking. Since mobile devices often operate on slower networks, unoptimized requests can lead to subpar performance.

4. Renderability and Indexability
Some network requests are essential for rendering content properly, especially on JavaScript-heavy websites. If critical assets fail to load or take too long, Googlebot may struggle to render the page, resulting in incomplete or inaccurate indexing.

What Google Clarified: Network Requests Do Not Directly Affect Rankings
During a recent discussion, Google's representatives confirmed that network requests, in isolation, are not used as a ranking signal. For example, the number of HTTP requests or the order in which resources are fetched does not contribute to your website’s position in search results.
However, these requests indirectly influence important ranking factors, such as usability, content accessibility, and performance. Simply put, Google cares less about the technical mechanics of network requests and more about their impact on the user experience.
Actionable Strategies to Optimize Network Requests for SEO
Now that we understand the role of network requests in SEO, here are actionable strategies to ensure your website meets Google’s performance and usability standards:
1. Minify and Combine Resources
Reduce the number of individual requests by combining CSS and JavaScript files where possible. Minifying these resources by removing unnecessary characters, spaces, and comments can also reduce file sizes.
2. Implement HTTP/2 Protocol
Switching to HTTP/2 allows multiple requests to be processed simultaneously over a single connection, reducing latency and improving load times.
3. Monitor Server Response Times
A slow server response can bottleneck network requests. Use tools like Google PageSpeed Insights or GTmetrix to identify server-related delays.
4. Preload Critical Resources
Use the <link rel="preload"> attribute in your HTML to prioritize loading critical assets like fonts or hero images.
5. Audit Third-Party Scripts
External scripts, such as those for tracking and advertising, can introduce significant delays. Remove unnecessary scripts or switch to asynchronous loading to reduce their impact on performance.
Tools for Diagnosing Network Request Issues
To optimize network requests effectively, leverage the following tools:
The Broader Implications for Technical SEO
While Google’s clarification may offer some relief, it should not lead to complacency. Technical SEO remains a critical component of an effective optimization strategy, and network requests are just one piece of the puzzle.
By ensuring that your site is fast, accessible, and easy to crawl, you’re not just catering to Googlebot—you’re also creating a seamless experience for users. In the long run, this is what will earn you higher engagement, better rankings, and greater online success.
