How to increase the speed of your website loading speed

A lot of people are aware that increasing the speed of loading a website by 0.5 seconds is not visible to users. It’s nevertheless one of the most important search engine elements they employ to determine the ranking algorithm. Additionally, a lot of web users might have an inefficient Internet connection even in the USA or Europe. Therefore, improving website loading speeds is a top job for web developers. How can we improve the website’s speed?

What is the speed of your website?

The technical term “loading” speed is not correct since it relates to the speed at which pages load.

In simple terms, the loading speed is the measure of how fast the website’s contents and the UI elements of the page load after the user goes to it.

A variety of factors can impact a particular page speeds:

  • The size and quantity of the videos and photos are shown on the page.
  • UI animations
  • These themes and plug-ins have been set up on the website.
  • Front-end and server-side technology is employed.
  • The code’s quality
  • Hosting or server

You should also be aware that the speed of your Internet connection also affects speed of web pages.

Start by testing the speed of your website

Start the site speed test using your smartphone or an Internet connection. Does your website load fast enough? Does your site look mobile-friendly? This test will help you find the root of issues with speed and also how responsive the design of your site is.

However, using a smartphone test cannot tell the score of a website on the basis of its speed of loading. It also doesn’t aid in identifying the cause of slow loading websites. This is why it’s important to make use of tools to evaluate and measure the speed of loading your site.

The most frequently used software most frequently used tool is Google Pagespeed Insights. It is simple to use and will provide you with the most crucial data. Check out the image.

Digitizer Sol team created this website. It has excellent scores and there are no major problems that could slow down the loading speed of the site.

In the event that Google Pagespeed Insights identifies issues and provides recommendations to improve the performance of your website.

The tool for free allows you to test the website’s desktop and mobile versions. You can utilize Lighthouse, the Lighthouse device which is integrated into the Chrome browser. Press F12 to launch the web developer tools and select for the Lighthouse software to run tests on the site.

Additionally, web developers could employ other tools, such as GTmetrixPingdom and The Performance Budget Calculator.

Certain tools are free, however other tools may be cost-based. Web professionals often make use of Lighthouse as well as the Core Web Vitals reports as it is generally sufficient.

Guidelines for improving the website’s loading speed

The Lighthouse tool (Google Pagespeed Insights) evaluated your website as being in poor condition (score less then 50) or a site which requires improvements (score between 50 and 89). Web developers must take a take a look at the suggestions of the tool and rectify any problems.

This guide will assist you understand the factors that influence the speed of websites and the best ways to improve it.

Optimize the images

Incredibly, images are among the most frequently encountered issues that impact the speed of loading a website. The reason for this lies in the fact that webmasters fail to take note of the dimensions and formats of the images they upload images to websites.

A typical image optimization.

Reduce the size of the image.

Images, photographs or images on web pages increase the engagement. If you make use of large files, they can will slow down the speed of a site.

Utilizing tools to compress images can help reduce the size of an image without affecting the quality. Another method to decrease the size of images is to alter the size of the image based on the characteristics of the user’s display.

Select the appropriate photo format.

Take a look at this picture. It demonstrates the difference between a vector image zoomed in L and a rasterized image R.

vectar and raster

As you can see, vector images are preferable options as they are resolution-independent and always deliver excellent results.

If you are using images that are rasterized, a web developer should offer different sizes of images to other devices. However, keep in mind that rendering desktop-sized images to mobile phones could consume 4 to 5 times more data than is needed.

Utilize WebP images

When Facebook made the switch to WebP and noticed a 25-35% reduction in filesize in JPEGs in addition to an an 80% reduction in filesize PNGs savings.

How do I convert images to WebP? Web developers typically use the cwebp command line tool (for small project) as well as using the Imagemin WebP plugin(for complex projects).

substitute animated GIFs by video.

GIFs aren’t the best option when you require an extremely fast website due to the size can range from 10 to 15 MB.


It takes a long time to upload an GIF file. This is the reason web experts transform GIFs to video file (MPEG as well as WebM).

Make use of image CDNs in order to improve the quality of images.

Image Content delivery networks (CDNs) specialize in changing the way they deliver, optimize, and distribute images. They are experts in optimizing images and result in an 40% to 80% reduction in file size. Image CDNs function like an API and allow users to make variations of images for various scenarios by specifying the parameters such as size formats, quality, and format.

Use lazy loading

The lazy loading technique is an process which delays loading of non-critical resources as the page loads. In reality, the image lazy loading process loads light placeholder images on page load and then replaces them with lazy-loaded images as they scroll in the browser viewport.

The use of lazy loading is logical in the case of a large number of multimedia files in your site.Web developers can employ various methods for lazy loadings like lazy loading at the browser level, Intersection Observer (JavaScript) and CSS. If your site was built using WordPress and you want to make it more user-friendly, you can utilize plugins.

Use a Content Delivery Network (CDN)

Content delivery networks (CDNs) improve site performance using web servers distributed across various locations. They retrieve web content from the server and deliver website content to users according to their geographical location. CDNs help reduce the load on servers and manage traffic spikes.

Furthermore, CDNs let you cache resources stored on their servers. This means that the resources are accessed faster. Cashing can also ease stress on server.

To select a good CDN You should concentrate the performance of its services, safety, features, support, as well as pricing.

It is important to understand the fact that CDN performance can differ significantly in accordance with location and time of day and the timing of various occasions. That’s why forecasting the exact performance you’ll receive from the CDN isn’t easy.

Selecting a reliable CDN is based on the nature of your website (e-commerce or corporate site or blog) and the location of your users, and the budget you have set.

Prioritize Loading Resources

Every website resource may not have equal importance, so browsers try to determine the essential websites that should load first. Unfortunately, browsers could use incorrect priorities for web resources – for instance, loading scripts prior to CSS files.

Web developers have many ways of influencing a browser’s decision-making processes.

However, if a web designer adds the code, they could take credit.

Priorities help us establish how much weight browsers accord various resources. Web developers can direct browsers to prioritize certain resources differently. For instance, if a web developer prioritizes an image component of initial rendering, it will rank higher than an image that stands independently.

Optimize CSS Code

CSS code must be loaded before any browser can render a page, as it acts as a rendering-blocking resource. If web pages contain unnecessarily large CSS codes, rendering will take longer due to loading the extra information and resources from their servers.

Web developers typically employ two major techniques when building sites.

The first step to CSS optimization: defer CSS; that’s optional. Many non-critical styles are applied to content that won’t immediately be visible, such as paragraphs in accordions; web developers can utilize non-essential code.

Minifying CSS files efficiently eliminates redundant comments, code, whitespaces and indentation within them. Experienced web developers can effectively eliminate unnecessary characters to reduce CSS size without impacting website rendering performance.

If web developers reduce CSS files, the suggestion “Minify CSS” will move into their Lighthouse report’s “Passed Audits” section.

Optimize JavaScript Code 

JavaScript code has become integral to modern website design; however, excessive usage may slow the loading speed. To improve JavaScript code used for maximum effectiveness and faster performance on websites.

Web developers should use the Lighthouse report to find and fix JavaScript issues and accelerate websites. There are common issues and possible solutions listed within.

First and foremost, JavaScript code on websites can be an extremely significant source of tasks. A task is any discrete work performed by the browser that impacts its performance – this may include rendering webpages and images, parsing HTML/CSS codes, running JavaScript code, etc.

Some tasks can take over 50 milliseconds. Web developers must break them up into smaller tasks that take less time using task management strategies such as async attribute, manually defer code execution or yield only when necessary. Selecting one depends on which features of a website’s usability must be considered when managing tasks – it all boils down to how users interact with it!

Minifying JS code is another effective way of speeding up websites. A web developer who wishes to minify their JS should remove whitespace and unnecessary codes to create a perfectly valid file containing only valid code.

JS code compression involves altering data using an algorithm. Most web developers utilize Gzip for server and client interactions; however, Brotli offers even greater compression results than its predecessor.

Also, modern JavaScript should be utilized to minimize website loading speed issues.

Modern JavaScript syntax is supported across modern browsers such as Chrome, Edge, Firefox, and Safari; however, its usage requires highly skilled web developers with advanced front-end and web app technologies.

We are transitioning a website to better hosting.

Hosting can often be the source of slow website performance; therefore, website owners should choose fast hosting to maximize its performance.

Hosting websites requires using various solutions.

Shared hosting is the cheapest solution, yet it remains one of the most popular choices due to its affordable cost. However, shared hosting also means sharing CPU and RAM resources among many other websites hosted on this server. If your site attracts many visitors or utilizes one of the more modern frameworks, dedicated or virtual private server (VPS) hosting may be required instead.

Virtual Private Servers (VPSs) and dedicated servers offer faster hosting services than shared ones. VPS hosting solutions meet the needs of many business and e-commerce websites, using multiple servers for content delivery and giving each website its own virtual server space.

Utilizing a dedicated server is the most costly solution since you must pay to rent or buy one and pay for the system administrator’s services.

Now, website owners have other solutions at their disposal for managing their sites. Cloud providers like Microsoft Azure, Google Apps or AWS provide high-quality services that can scale to meet the demands of website owners on an as-needed basis.

Another promising approach is serverless computing.

Selecting the ideal hosting provider can be challenging but well worth your while.


Search engines now consider website loading speed a critical criterion when ranking sites, impacting both visitor numbers and revenue for businesses.

Use one of the available tools to test the speed of your website and see if improvements are required. A score below 89 indicates your site requires attention – image optimization and minification of CSS/JS can speed up the website’s performance. Still, as is evident by its complexity, this task should be undertaken with a grain of salt.

Hiring skilled web developers capable of writing quality, optimized code is also crucial since optimizing a website developed by less experienced specialists is near impossible; in such an instance, starting from scratch becomes the easier, faster, and cheaper solution.
