In this example, we’ve preloaded the essential assets that will immediately impact how fast the page renders, like fonts, stylesheets, and images.
When Not to Use rel="preload"
While preload is powerful, it’s not a magic solution for all resources. Here are a few cases where you might want to avoid using it:
Non-Critical Resources: Don’t preload assets that aren’t essential for the initial rendering of your page.
Unpredictable Resources: If certain assets are conditional or depend on user interaction (like below-the-fold images or deferred JavaScript), it’s best to let the browser fetch them when needed.
Conclusion
Using rel="preload" is a simple yet effective way to speed up your website by telling the browser to fetch critical resources as soon as possible. By focusing on preloading essential assets like fonts, stylesheets, and images, you can reduce load times and enhance user experience.
The key takeaway: preload only what’s critical, and your website’s performance will significantly improve. Give it a try on your next project and see the difference it makes!
