Website speed is one of the important factors affecting user experience, supporting conversions and increasing search rankings of a website. A website in addition to containing useful information, fast loading speed will always be the top priority for users. Improving speed will help the website achieve greater efficiency and better profitability.

What is website speed?

Website speed is understood as the website loading time for a specific website visit.

What factors affect website speed?

  1. Internet speed

The Internet speed of the access device is a fairly common factor, which has a decisive influence on website loading speed. The same website on two devices using two different Internet networks will show a different loading speed.

Internet speed depends on: the Internet package you are using, the number of people using the same network, the Internet connection speed.

  1. Website capacity

Website capacity includes content capacity, image capacity, characters, moving background effects, etc. If it contains too much of that capacity, it will make the website heavy. That is also a factor that affects website speed.

A beautiful website that uses too many visual and motion effects often contains a lot of files that increase the size and capacity of the website. A heavy website will take more time for users to load and wait for the website to fully display.

In addition, high-quality uploaded images and videos always take up a lot of space, causing the website to take a lot of time to fully respond to all the information therein. Images and videos that are not optimized will affect website loading speed.

  1. Number of ads on the website

Advertising on websites is extremely popular today, it brings in great revenue. If you insert enough ads, it won’t have much impact, but when there are too many ads appearing, it will make the website harder to access and slower, sometimes causing discomfort for users.

  1. Cache (data buffer)

Browsers all have a facility to store cache data for users because most users need to save certain information so they can use it the next time they visit the website. . This buffer data brings great convenience to customers who want to store it. When data is stored, the next time you want to access the website it will take less time to load because the data has been “remembered”, there is no need to reload from the beginning.

  1. Configure the device used

Each device such as laptop, phone,… has different large and small configurations depending on the brand and type of customer using it. The device configuration you use also has a certain impact on website speed. Even though the network connection is good and the website capacity is not large, a computer with a strong configuration can load the website faster than a machine with a weaker configuration.
