How to Increase Website Loading Speed: 12 Optimization Techniques

[Mimaktsa10]

Loading a website equally requires the participation of both the user and the server where the website files are directly located.

The problems are as follows:

due to lack of RAM or cores in the processor, the server is running slowly;

the site has a slow engine (CMS). This happens if the programmer, due to his inexperience, wrote the code without taking into account the speed;

a large distance between the malta email list user and the server. If, for example, you make a request from Irkutsk, and the files are stored on a Moscow server;

large file size.

Below are steps to help you work around these issues.

Step 1. Optimize images

The largest weight on the site is carried by unoptimized images. Correcting images can significantly increase the loading speed of the site.

The following points should be taken into account:

The height and width of the image. For example, your product photo turned out to be 5000 pixels wide. This is a lot, usually 1600 is enough, so feel free to reduce it. A larger size is only necessary for sites (usually online stores) that have a magnifying glass function. Moreover, even there, the enlarged image is loaded only when the user clicks on the magnifying glass.

Image weight in kilobytes. If you used a camera, always compress the image before posting it on the site. Use the same Photoshop or something similar. Or online tools like Optimizilla or TinyPNG.

Previews (reduced images) for large images. It makes sense to make them if you have pages with a list of all photos of products or your works. Then the site loading speed will increase due to the fast loading of the list of products, works or photos.

On the Sportmaster website, for example, there are images made in three different sizes:

in the product list the images weigh 7 KB;

in the product card - 18 Kb;

for viewing with the magnifying glass function - 942 Kb.

It's not hard to imagine what the loading speed of a website would be if all the images there were only 900 kilobytes or more in size.

Testing via Google Page Speed ​​immediately produces a list of images whose size requires adjustment:

Gzip compression

Step 2. Gzip compression

The Gzip service works similarly to zip archives on a computer, i.e. it compresses files. How does this affect the site loading speed? If the Gzip function is activated, the server will archive files with scripts, styles, and other texts before sending them. And unpacking will occur on the user's computer. In compressed form, information travels faster from the server to the browser.
