IMPORTANCE AND STEPS TO FOLLOW TO SPEED-UP YOUR WEBSITE PERFORMANCE.

Finding out what is slowing down your website's performance will help you get it to load quicker in short order. Use Google's PageSpeed Insights and review their suggestions. If you fail to speed up your site, potential visitors will hit the back button and find a competitor who has a site which loads quickly. Nearly half of a website's visitors expect the site to load in three seconds or less. If the site does not, they will leave.

Google also punishes sites which load slowly with a lower rank. People perform most searches on mobile devices and mobile users don’t want to waste data on a slow loading site. Google wants to give its user the best results, so sites that load quickly rank better than ones that do not. To speed up your website:

Compressing Your Files

Compressing your CSS and HTML files with Gzip is an easy way to make your site load faster. Smaller files can reduce your sites load time significantly.

Reduce Image File Sizes

Large, glorious images engage visitors, but they can slow your site's performance. Crop images to the correct size before loading them; otherwise, the large image will have to load and then adjust in size, slowing down your site.

Host Your Videos on YouTube

If several visitors watch one of your videos on your site, it can eat up your available bandwidth. Host your video on YouTube and then embed it on your site. Your visitors will thank you.

Review Your Hosting Provider

Sometimes, when a person creates their website, they choose low-cost shared hosting. If the site takes off, the server you're on may not be able to handle traffic spikes. Consider upgrading to VPS hosting or dedicated hosting. It's more expensive, but worth it if your website can handle high-volume traffic.

Consider a CDN if You Have International Visitors

A content delivery network will have a network of servers in different locations worldwide. A CDN will route visitor's requests to the closest server, eliminating any frustrating lag.
