Lazy loading of off-screen images (also known as image lazy loading) refers to the use of a set of techniques to load only the images that visitors are currently looking at. Off-screen images become visible only when the user navigates to them. Deferring them ensures that the most critical resources are loaded first.
6. Serve static assets with an efficient caching policy
Of all the ways to improve website performance, caching is the most fundamental. If you want to speed up your website performance, reduce the load on your server, and provide visitors with an exceptional iraq telegram data experience, you definitely need to have an efficient caching policy in place.
7. Make sure the text remains visible while the web font loads
Fonts are often large files that take a while to load. They can even block the rendering of text, which is what visitors need most to navigate your website. That's why ensuring that text remains visible during web font loading is a critical part of your overall performance strategy.
8. Image elements do not have explicit width or height
One of the main reasons why most websites fail to pass the CLS score is because they don't have enough space reserved for their image elements. That's why having explicit width and height attributes can save you from CLS issues and prevent your visitors from experiencing unexpected shifts.
9. Reduce the impact of third-party code
While it's impossible to run a website without third-party scripts, there are many optimization techniques you can apply to reduce the impact of third-party code. Doing so will allow you to continue using useful functionality without slowing down your website.
Conclusion
Google PageSpeed Insights is worth adding to your performance testing arsenal, but don’t forget to use it wisely and focus on the data that matters. Getting a 100/100 score isn’t your primary goal. Instead, shift your attention to the Core Web Vitals assessment at the top of your PSI report. A low performance score indicates technical issues on the site—use it for debugging purposes. Field data trumps lab data if you want to reap the benefits of a great user experience. Revisit the PageSpeed tool to stay on top of Google’s priorities and track your CWV progress every 28 days.
