How to improve a website performance is becoming more and more important in increasing the user experience. If your website is not responsive or there is a significant delay, users will leave your website to look for a competitor. And the following article, DanaWeb will guide you on how to improve website performance most effectively.

1. What is website performance?

Website performance is a measure of how fast a website loads. Websites with fast page loading speeds will satisfy the needs of customers and vice versa. Because your customers don't have much time to wait, they will leave quickly.

a. Factors to evaluate website performance

Factors that determine the loading speed of a web page include various elements of the web page such as CSS, js, jquery, images (png/jpeg/gif), HTML.

Other factors that should be considered are:

• First Byte arrival time
• PageSize
• Number of requests
• Your server location
• Image quality

b. Why is website performance important?

When it comes to page load speed, every second matters. According to a Google study, when page load time increases from one to three seconds, users leave by 32%. If a page takes 5 seconds to load, users leave 90% of the time:

In other words, if your web pages don't load within the first few seconds, it greatly increases the chances of visitors leaving your site. Additionally, Google considers many factors when deciding how to rank web pages, and page load speed is an important ranking signal.

Therefore, if you want to run a highly effective website, you need to focus on optimizing the page loading speed.

c. Website performance measurement tool

Here are free website performance testing tools. These services are used to measure the speed of any website and they also provide various tips for optimizing your website.

GTMetrix

GTMetrix uses Google Pagespeed API & Yahoo YSlow API to evaluate page performance. The tool also gives you a descriptive waterfall image to let you know your performance.

The results can be easily interpreted even by a non-specialist in identifying and correcting areas that need improvement. It also gives you data on page load time, page size, and response count.

Web Page Test

Web Page Test is a popular tool with some extra options like choosing internet connection type, test location, test browser, number of tests, etc.

Web Page Test gives you more detailed page load segments like:

• Loading time
• Takes time for the first Byte
• Time to start rendering
• Takes time to load the document completely
• Number of requests and sizes to load documents
• Time, number of requests, and size for a fully loaded page.

Google Pagespeed Insights

Google Pagespeed Insights is Google's official website performance testing tool. The tool gives you a score from 1 to 100, where a score of 85 and above is considered good.

It provides results for both desktop and mobile versions of the website, and it also gives a breakdown report into different factors that affect page speed.

In summary, there are many different tools offered by different companies. However, I have listed a few tools commonly used by many webmasters.

2. How to improve a website performance

a. Compress images

If your site contains large images, your site's load time may take minutes instead of seconds. To speed up this process, we recommend that you compress images before using them on any website.

b. Minify CSS and Script in HTML

It is recommended to remove any unnecessary formatting, comment fields, or site code that are not needed, thus improving the performance of your website.

Also, find a way to keep your content concise while still covering the breadth and depth of your topic if needed.

c. Choose the right Web Hosting

Most website owners choose the cheapest hosting option from the start, such as shared hosting. However, if your website starts to see an increase in traffic, you can switch to another type of hosting to increase performance and ensure a successful user experience. You can refer to suitable Hosting packages for your Website at DanaWeb.

d. Using Static Cache

With a static cache policy, after a visitor re-visits your site a second time, there is no need to send another HTTP request to the server because the information from the previous visit is already stored in the user's cache visitor (temporary memory).

e. Using CSS Font-Display

A great option to increase page speed is to apply CSS font rendering, which is responsible for how font files are downloaded and displayed in the browser. With this code, you can display the web page content before it has finished loading.
