I’ll show you more ways that you can reap the benefits of site speed optimization beyond the basics, focusing on improving user-centric performance metrics and the critical rendering path.
What are user-centric performance indicators?
I highly recommend reading this article by Google about user-centric performance metrics . The metrics we’ll focus on are those from the updated PageSpeed Insights tool and Google’s Lighthouse tool .
The critical rendering path is the steps that a browser completes to render and display content on a web page.
If you don’t understand what the critical rendering path is, I highly recommend checking out the following articles:

When looking at site speed optimization, it’s important that ecuador mobile database you focus on the critical rendering path. If you’re optimizing for page load time and not measuring user-centric metrics through tools like Lighthouse, you’re doing it wrong!
For example, if your page loads in 6 seconds, but the user can see and interact with the page in under a second, that's not bad.
If your page loads in 6 seconds, but the user waits 5 seconds before seeing anything or interacting with the page, that's very bad from a user's perspective.
This is a pretty obvious comparison, but you get the point. By optimizing the critical rendering path, you can focus on perceived loading times, which is what really matters to your users.
