In terms of usability, website speed matters. The best interface from the mind of man is pointless if the user gets too impatient.
Long story short, websites should be fast; otherwise, you’ll lose visits.
When it comes to website speed, the faster the better. Users do not appreciate waiting and if your site fails to deliver on time, they aren’t going to stay. But how fast should fast be?
Website Definition of “Fast”
According to Denver Data Web, there’s no such thing as “too fast” for websites. But for most of Denver’s web developers, there are different types of “fast” in the realm of the internet; specifically, there are three kinds:
- Loading time – This refers to the time it takes to download all information to the user’s devices; primarily affected by the internet connection’s speed and the files’ actual sizes
- Processing time – After downloading all the files, the browser processes and renders gathered information.
- Perceived website speed – In some cases, even the fastest websites feel and look slow. Slower websites, on the other hand, use secret tricks to feel a bit faster. This part requires studying the user and letting them know the app or site’s current comings and goings.
Like CSS, keeping JS in external files linked to the HTML is helpful, but here’s another thing: browsers cache JS and CSS files. So when the users request the same page, cached external files are used instead of being downloaded again.
Improving its performance makes a big difference. Reduce perceived loading time and improve user experience by linking all external files at the bottom of the page. Once the user interacts with anything in need of JS, the page should be ready to go.
