Website speed optimization is a major factor in SEO, and it’s one that many businesses are still struggling with. However, if your site isn’t optimized for speed, you’re losing money to competitors who have made an effort.

The stakes are much higher when running a global website as it can be hard to optimize for each country. Thankfully, there are ways to manage your site’s speed across different countries to ensure they have the best experience possible.

What are the pros and cons of a global website?

Global websites are designed to support an international marketing strategy and expansion by presenting users with multiple language choices. The benefits of a global website are replete. Not only can you reach a larger audience, but you can also have content specifically tailored to different audiences.

Yet, the cons of a global website are that providing a seamless experience to your global audience takes time and effort. A website may work well in one location but perhaps not the other, hurting your chances of converting those visitors into customers. That’s why website speed optimization for global websites needs a more targeted approach.

What are the metrics that matter for your global website?

Core Web Vitals

The Core Web Vitals is a set of metrics formed by Google as a standard to help developers interpret how a visitor experiences a web page. It evaluates the Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS), and the newest being Interaction to Next Paint (INP).

This metric is applicable to every site, global or not. You can run your site through a global website speed test via PageSpeed Insights or GTmetrix. Nevertheless there are some specific website performance metrics if you are running a SMB website.

Data from Google Analytics

Apart from the usual CWV metrics, website speed global optimization strategies should also examine data from Google Analytics.

Google Analytics has a lot of great data on how users in different areas are using your site, including where they come from (Audience > Geo for Universal Analytics and Reports > Demographics >Demographics details: Country for Google Analytics 4) and how long they stay on the page before leaving (Behavior). You can use this information to ensure your site loads fast enough in every area.

Google Analytics’ handy map feature shows the “heat map” of your global website’s top visitors.

In particular, these are the metrics that matter most:

  • Traffic: The number of visits and visitors to your website (sessions and users) is a key measurement of site reach and growth.
  • Bounce Rate: Indicated as a percentage of single-page site visits, bounce rates reflect user engagement and the quality of content. Yet, website speed in different locations may also affect this metric.
  • Pages Per Session: This measures the average number of pages viewed when a user visits your site.
  • Average Session Duration: This indicates the average length of all site visits.

The above metrics help inform you whether or not your website speed global is doing well. For example, if you see high bounce rates from a specific location, it might indicate that users from that location may experience slow page loading speeds compared to others with lower bounce rates.

Data from Real User Monitoring Tools

Another useful metric is data from real user monitoring (RUM) tools. Unlike synthetic monitoring, it helps to estimate the quality of user experience based on network connectivity, page load times, and interactivity.

Page speed international website needs just more delicate care. Website speed test global using RUM goes beyond examining Google’s web vital data and considers geospatial data such as country, city and ISP. This helps companies with global websites segment their visitors based on geographical regions so they can better understand how their web pages load across the world.

How to improve global website speed?

What are the ways to improve website speed and page speed? Are they the same for global websites? Let’s have a look:

improving global website speed
These are some of the quick ways to improve global website and page speed.

Optimize images

Since images take up the most page weight on a site, having images that are too large and take too long to load is obviously going to slow down page load times for all users - but especially for those who live in places with slower internet speed or slower connections (such as rural areas).

To solve this problem, image optimization is necessary to reduce files without losing quality and will drastically speed up page load times.

Use responsive images

Nowadays, users no longer keep to a single device to surf the internet. Responsive images are key in ensuring that your website works well across devices. By implementing responsive images, you don’t need to use a large image on a small mobile screen, which helps boost your site’s performance.

Optimize videos

Many websites now make use of videos to improve the engagement of users on the website. Optimizing videos using video transcoding and adaptive streaming technologies will eliminate the annoying problem of buffering.

Utilize Content Delivery Networks

How CDNs work is that it caches content at the nearest possible points-of-presence (PoPs). When the website content is cache in the nearest PoPs, users can access your website much faster than if you do not already have a CDN. After all that optimization, delivering all your images over Content Delivery Networks is necessary.

Other than improving website speed, CDNs can also help protect your global website from malicious intruders.
