Six great ways to improve your web page loading time

【51CTO.com Quick Translation】 Aberdeen Group once conducted a survey on users, and the results showed that for every 1 second increase in website page loading time, page views will decrease by 11%, customer satisfaction will decrease by 16%, and conversion rate will decrease by 7%. Amazon also confirmed through a survey that for every 100 millisecond increase in the speed of web page opening, the website can increase revenue by 1%. There are many similar confirmations. The speed of web page opening is directly related to the website's revenue, which is beyond doubt.

That’s why today’s businesses and individuals are doing everything they can to reduce web page loading times. Time is money, and for websites, it’s measured in microseconds. A significantly faster page loading time will also lead to an increase in conversion rates.

How to Improve Website Speed
1. Image Optimization <br /> Statistics show that users tend to abandon a web page that does not load within 3 seconds. Since loading images takes up most of the downloadable bytes on a web page, the key to influencing web page download time comes from image optimization. One of the best ways to ensure proper image optimization is to use the right size and format (JPEG, GIF or PNG). The goal is to reduce the file size as much as possible without affecting the quality of the image.

2. Try CDN acceleration <br /> The value of a content delivery network is that it can take a website's static files, such as CSS, images, and JavaScript, and deliver them through a web server that is closer to the user's physical location. Shorter proximity equals faster loading times. AWS CloudFront or CloudFlare are good CDN acceleration. Another benefit of CDN is that even if you stop loading bandwidth, you can still reduce the risk of interruption during peak download times. From all aspects, CDN can bring a win-win situation.

3. Cache <br /> Cache is a mechanism for temporary storage of web pages that reduces bandwidth and improves performance. When a visitor arrives at your site, cache mode is activated. This saves server time and improves efficiency. Enabling browser caching will allow repeat visitors to access your site more quickly.

4. Compression
Gzip is an application used for file compression software, just like turning your website into a zip file. Most servers and clients support Gzip. When a Gzip-compatible browser requests the server to send the response to the browser resource, it can significantly reduce the time delay of the website.

5. Clean Code <br /> It is imperative to make your code cleaner. This means bundling and compressing your HTML, JavaScript, and CSS files into smaller files to run. For example, if your mobile website has five JavaScript files, the browser will make five separate HTTP requests to fetch them. To reduce congestion and waiting time, another approach is to minify and concatenate these five files together.

6. Check Your Web Host <br /> Another easy way to reduce your site's page load time is to check your hosting provider to see what kind of package you have. Shared hosting accounts often involve sharing server space with dozens of other companies, and the speed of your site can be affected by the number of people using the server. If that's the case, then it might be time to consider a dedicated access server plan.
