Page speed insights is a free tool from Google that shows how fast a website loads on phones and computers. It checks your site and gives it a score from 0 to 100, where a higher number means the page is faster and easier to use. By using this tool, we can find exactly what is slowing down our pages and learn how to fix those problems to keep our visitors happy.

How to understand page speed insights scores

When we run a test, the tool shows a large circle with a number that tells us the speed of the site. This score uses colors like a traffic light: green is good, orange is okay, and red means the site needs a lot of work. We use page speed insights to check our progress and make sure our website stays fast as we add new content or pictures.

Learning about core web vitals

Core Web Vitals are three simple things that Google measures to see if a website is friendly to use. One measure looks at how fast the main content shows up, another checks how quickly the page reacts when you tap a button, and the last one makes sure the page doesn’t jump around while it is loading. If these three things are working well, your website will feel smooth and reliable to everyone who visits.

Difference between mobile and desktop scores

The tool gives us two different scores because a phone is not as powerful as a big desktop computer. Most people in Nepal use their phones to get online, and mobile data can sometimes be slower than home internet. We focus on making the mobile score high first, because if a site works well on a phone, it will definitely work great on a fast computer.

Reading the opportunities and diagnostics

Below the main score, there is a helpful list called Opportunities that tells us exactly what to fix to save time. For example, it might tell us that our pictures are too big and taking too long to load. We treat this list like a to-do list for our website. Fixing even a few of these items can make the site feel much faster for a normal person browsing the web.

Improving core web vitals and technical performance

Improving a website means making it lighter so it can travel through the internet faster. We focus on the most common issues the tool finds, such as photos that are too large for a small phone screen. Using the tips from page speed insights helps us make sure the website does not waste any of the user’s time or mobile data.

Optimizing images for faster loading

Images are usually the heaviest part of a website and the main reason why pages take a long time to show up. We use modern picture types, like WebP, which keep the images looking great but make the files much smaller and easier to download. We also tell the phone exactly how much space a picture will take up before it appears. This stops the text from moving up and down while the user is trying to read.

Making the main content show up first

Sometimes a website waits for hidden code to load before it shows the text or pictures that people actually want to see. We fix this by telling the browser to focus on the main words first instead of the extra background code. This makes the website feel almost instant to the user. When the main content pops up quickly, people are much more likely to stay and read what we have written.

Using browser caching to save time

Caching is a way for a website to remember some parts of a page so it does not have to download them every single time. For example, once a visitor’s phone downloads our logo, we tell the phone to keep it in its memory for the next visit. This makes the website load much faster when the person comes back later or clicks on a different page on the same site.

Advanced methods for page speed insights optimization

Once the basic fixes are done, we can use even better tricks to make the site even faster. We look at how the main computer that holds the website, called a server, sends information out. By following the advanced advice in page speed insights, we can make our website load so fast it feels like it is already saved on the user’s phone.

Reducing server response times

The time it takes for a server to send the very first hello to a phone is very important. If the server is slow or located in a different country, the website will always feel sluggish no matter what else we do. For our users in Nepal, we try to use servers that are close by or use special networks that bring the data closer to them. A fast server is the foundation of a fast website.

Cleaning up unused code

Many websites have extra code that they do not actually use, which is like carrying a heavy backpack full of rocks. We go through the site and remove any code that is not needed for the page to work properly. This makes the files smaller and helps the phone’s brain work less to show the website. Less code always leads to a faster and better experience for everyone.

Using lazy loading for pictures

Lazy loading is a smart way to wait to download pictures until the person actually scrolls down to them. If a page has ten pictures but the user only sees the first one, the phone will not waste time downloading the other nine right away. This saves a lot of mobile data and makes the top of the page load much quicker. It is one of the best ways to help people who have a slow internet connection.

Frequently Asked Questions

Is a score of 100 necessary? 

While a 100 is great, a score in the green zone (90 or above) is usually enough to give users a fantastic experience.

Why does my score change every time I test it?

 Internet speeds and server traffic change all the time, so the score might change slightly each time you click the button.

Does a fast site help me get more visitors? 

Yes, search engines like fast sites more, and people are much more likely to stay on a website if they do not have to wait for it.

What is the most important thing to fix?

 Usually, making your pictures smaller is the fastest way to see a big improvement in your score.

Is the desktop score more important?

 No, the mobile score is more important because more people browse on phones, and it is harder to make a site fast for a small screen.

Conclusion

Using page speed insights is the best way to make sure our website is fast and easy for everyone to use. By making our pictures smaller, cleaning up our code, and using fast servers, we build a site that people enjoy visiting. Keeping an eye on our scores and making small changes over time helps us stay ahead and provides a great experience for all our users.
