How to improve website loading speed?

  • Optimize images Compressing an image while uploading it to a server is a good way. In the case of e-commerce, website images are an important part. Improve user engagement by images on the product page. Images over 100 kb in size take a lot of time to load; as a result, the speed of the entire page is affected.
  • Use a CDN Content Delivery Network is a distributed network of network servers where multiple copies of websites are stored in various parts of the world. CDN helps deliver content requests to users from the immediate location of their server; as a result, server load time is greatly reduced.
  • Delete unused CSS CSS is used to decorate your website. According to unuse, 35% of the CSS used on the website is unused. Identifying unused CSS files and deleting them can be a great way to improve website speed. This tool can be used to locate unused CSS files and compress them.
  • Minify JS and CSS files JavaScript is a link to build a website. As the number of JavaScript files increases, the number of https requests increases. Reducing JS and CSS files reduces empty spaces, reduces unwanted comments. It also helps to reduce the name of the activity and classes. Minification techniques are used to reduce the size of the byte code, and as a result, less data needs to be downloaded, which in turn reduces the loading time of the website.

Excellent minification tools:

  1. To minimize HTML, try HTMLMinifier
  2. To use CSS, try CSSNano and CSS.
  3. To do a little JavaScript, try Uglify.
  • Make good use of Web fonts Typography is an important factor when considering a website design, readability, and accessibility. Using the right Webfont ensures that you follow the best practices outlined above by Google. Each font is considered an additional resource that needs to be loaded. Sometimes improper use of fonts leads to website blockade leading to increased loading time.
  • Use Prefetching techniques As the name suggests, in this method, resources are preloaded or provided before the user demands them; as a result, resource loading time is saved. Eg. When a user clicks on a link and visits a website, some of the content and links are already preloaded. In order to use this approach, we need to anticipate user behavior and appropriately plan actions on our website.

The most widely used Prefetching techniques:

  1. DNS – Download first
  2. The download starts the link
  • Reduce Excess DOM size DOM, also known as the document object model, is an independent visual interface for HTML and xml documents. Sometimes as a result of inefficient coding techniques, large and unnecessary DOM trees are created, which disrupts the speed of the website.

According to the Google Developers’ Guide, the best DOM size you have

  1. A number of nodes less than 1500.
  2. maximum depth of 32 nodes.
  3. Parent node with more than 60 sites for children.
  4. The Lighthouse tool is a great way to check how much of your website has a DOM size problem. This is how the torchlight bulb report of the DOM excess case
  • Use lazy uploads Lazy loading is a terrible way to reduce website loading time. In this website speed mode, only the requested part of the website is loaded, and everything is kept up to date until the user requests that part. Example: A user is using a mobile web application. When a user drops a picture or object on the screen it is loaded, and all parts of the website are rewind; as a result, website load time can be significantly reduced.


Running a website is a daunting task. Finding the right website speed is a must for all businesses. According to Google, the user expects the web page to load within 3 seconds. To meet expectations, we as SEO experts must ensure that a thorough analysis is carried out to determine key points; otherwise, there is a chance that we may lose live traffic and revenue.
