Many people know that improving the website loading speed by 0.5 sec is invisible to the users. But it’s still one of the essential search engine factors they use in their ranking algorithms. Also, many web users may use a slow Internet connection, even in the USA and Europe. That is why improving website loading speed is a high-priority task for web development teams. How to improve the website speed?

What is website speed?

Technically the term website loading speed is incorrect because it is about page loading speed. 

In short, website loading speed refers to how quickly the content and UI elements of the specific page load when a user visits it. 

Several factors can influence specific page speed: 

  • The amount and size of the images and videos are contained on the page
  • UI animations
  • Themes and plugins are installed on the site
  • Front-end and server-side technologies are used
  • The code quality
  • Hosting or server

But you must know that the user’s Internet connection also affects the web page speed.

Start with website speed testing

You may start the website speed test with your smartphone and mobile Internet connection. Does your site load quickly enough? Does your site look mobile-friendly? This test helps you to identify critical speed issues and how responsive the design of your website is.

But using a smartphone test can’t tell about a website’s score in terms of the website loading speed. Also, it can’t help to identify the causes of slow website loading. That is why you should use tools to test and measure your website’s loading speed.

The most used tool is Google Pagespeed Insights. It is easy to use and provides you with the most critical information. Look at the snapshot for our website.

AHN’s team developed this site. You can see good scores and no critical issues that could affect the website loading speed.

If Google Pagespeed Insights identifies issues, it will provide recommendations for increasing the website’s performance.

This free tool allows testing the site’s mobile and desktop versions. You can use the Lighthouse tool that is built-in Chrome browser—Press F12 to run web developer tools and choose the Lighthouse tool to test the page.

Also, web developers may use other tools like GTmetrix, Pingdom, or Performance Budget Calculator. 

Some tools are free, but other tools can be payable. Many web professionals use Lighthouse and Core Web Vitals reports because it is usually enough.

Guidelines to improve the website loading speed

The Lighthouse tool (Google Pagespeed Insights) assessed your site as poor (score is less than 50) or as a website that needs improvements (score from 50 to 89). A web developer must look at the tool’s recommendations and fix issues. 

This guide will help you to understand which factors influence website speed and how to increase it.

Optimize the images

Surprisingly, images are one of the most common issues affecting website loading speed. The main reason is that content managers do not pay attention to the size and format of the images when uploading them to the website.

There is a typical image optimization process.

Reduce the image size.

Photos, images, or graphics on the web pages improve engagement. But if you use large files, the images slow down a website.

Compressing images using tools is one way to reduce image size without affecting quality. Another way to reduce the image size is to adjust the image size based on user display properties.

Choose the right image format.

Look at this image. It shows the difference between a zoomed-in vector image L and a raster image R.

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

If you use raster images, a web developer should serve different image sizes to other devices. But bear in mind that serving desktop-sized images to mobile phones can use 2–4x more data than needed.

Use WebP images

When Facebook switched to WebP, they noticed a 25-35% filesize savings for JPEGs and an 80% for PNGs.

How to convert images to WebP? Usually, web developers use the cwebp command-line tool (for simple projects) or the Imagemin WebP plugin(for complex projects).

Replace animated GIFs with video.

GIFs aren’t a good choice when you need a fast website because their size can be 10-15 MB.

It takes a lot of time to upload a GIF file. That is why web professionals convert GIFs into video files (MPEG or WebM).

Use image CDNs to optimize images.

Image content delivery networks (CDNs) specialize in transforming, optimizing, and delivering images. They are excellent at optimizing images and can yield a 40–80% savings in image file size. Image CDNs work like API, making it easy to create variations of an image for different use cases by indicating parameters like size, format, and quality.

Use lazy loading

Lazy loading is a technique that defers the loading of non-critical resources while the web page loads. In practice, the image lazy loading loads lightweight placeholder images at page load and replaces them with lazily-loaded images when they’re scrolled into the viewport.

Using lazy loading makes sense if you use many media files on your site.
Web developers can use a variety of ways to implement lazy loadings, such as browser-level lazy loading, Intersection Observer (JavaScript), or CSS. If your website is built on WordPress, you can use plugins.

Use a Content Delivery Network (CDN)

Content delivery networks (CDNs) improve site performance using web servers distributed across various locations. These servers retrieve content from the website server and provide website content to users with regard to their location. CDNs reduce server load and handle traffic spikes. 

Also, CDNs allow caching resources on their servers. As a result, the resources are delivered more quickly. Cashing also reduces the load on the website server.

To choose a good CDN, you should focus on its performance, security, analytics features, support, and pricing. 

You need to know that CDN performance can vary significantly depending on geography, time of day, and different events. That is why predicting the exact performance you’ll get from a CDN is difficult.

Choosing a good CDN depends on the type of your site (e-commerce, corporate website, blog), user locations, and your budget.

Prioritize loading resources

Not every website resource has the same degree of importance, which is why browsers attempt to make a guess at the most important resources to load first. The problem is browsers could use the wrong priority for website resources. For example, loading scripts before CSS.

Web developers can use different ways to influence browsers’ priority-making process.

If a web developer adds the <script> tag in the page’s <head>, Chrome will load at a high priority. But using the async attribute changes it to low priority.

Also, a web developer can use <link rel=”preload”> (informs the browser that a resource should start getting fetched as soon as possible), <link rel=”preconnect”> (informs the browser that you’d like the process to start as soon as possible), and <link rel=”prefetch”> (it tries to make something non-critical happen earlier if there’s a chance) for other resources.

To make everything right, a web developer should know the browser’s priority for each resource. For example, to know Chrome’s priority, you need to press F12 to run DevTools and find the Network panel.

These priorities help to understand how much relative importance the browser attributes to resources. A web developer can influence the browser to assign a different priority. For example, if an image is a part of the initial render, a web developer prioritizes it higher than an image that starts offscreen.

Optimize CSS code

CSS code must be loaded before the browser renders the website page because it is a render-blocking resource. If these web pages contain unnecessarily large CSS code, it takes longer to render them.

There are two main techniques that web developers use.

The first is deferring non-critical CSS. Many non-critical styles apply to content that’s not immediately visible, for example, paragraphs inside the accordions. A web developer can defer this non-critical code.

The second is minifying CSS. Minification CSS files is a technique that reduces unnecessary code, comments, whitespaces, and indentation in CSS files. A professional web developer can safely remove unnecessary characters and reduce CSS file size without affecting website rendering. 

If web developers minify CSS files, you will see that recommendation “Minify CSS” moved to the “Passed Audits” section of the Lighthouse report.

Optimize JavaScript code

JavaScript code is a critical part of modern website design. On the other hand, using JavaScript code may slow down a website’s loading speed.

A web developer should analyze the Lighthouse report to fix JavaScript issues and speed up a website. There are most common issues and solutions.

First, the JavaScript code used on the website is a significant source of tasks. What is a task? A task is any discrete piece of work that the browser does and impacts the website’s performance. It can be rendering, parsing HTML and CSS, and running JavaScript code.

Some tasks can be too long (that take more than 50 milliseconds), and a web developer should break up such tasks. In other words, a web developer needs to divide a long task into smaller tasks that take less time using one of the task management strategies like the async attribute, manually defer code execution, yield only when necessary, and others. Choosing a strategy depends on the main website features you’d want to consider when managing tasks because it is about usability and how users interact with a website.

Minification JS code is another way to improve a website’s speed. To minify JS code a web developer should remove whitespace and any code that is not necessary to create a perfectly valid code file.

JS code compression is the process of modifying data using a specific algorithm. Most web developers use Gzip for server and client interactions, but Brotli is a newer compression algorithm that helps to achieve even better compression results than Gzip.

Also, we recommend using modern JavaScript to avoid reducing the website’s loading speed.

Modern JavaScript means syntax supported by all modern browsers such as Chrome, Edge, Firefox, and Safari. But using modern Java Script requires high-skilled web developers who have experience in advanced front-end and web app technologies.

Move a website to better hosting.

In some cases, the leading cause of slow website speed is hosting. A website owner must choose fast hosting to optimize the website’s performance.

Several solutions can be used to host a website.

Shared hosting is the most popular solution because it is cheap. But shared hosting means that you share the server’s CPU and RAM with many other sites that are also hosted on this server. If you need more RAM and CPU because your site attracts many visitors or use one of the modern frameworks, you need Virtual Private Servers (VPS) hosting or a dedicated server.

Virtual Private Servers (VPS) and dedicated servers are faster than shared hosting. VPS  is fit needs of many business and e-commerce sites because it uses multiple servers for content distribution and provides your own part of the virtual server.

Using a dedicated server is the most expensive solution because you need to rent or buy a server and pay for the system administrator’s services.

Now alternative solutions are also available for website owners. You can use cloud solutions like Microsoft Azure, Google, or AWS. Cloud providers provide quality services that can scale on demand for your needs.

Another alternative option is the serverless approach.

Choosing a hosting provider is not easy but worth the effort.

Conclusions

Currently, a website’s loading speed is a vital factor that search engines assess, affecting website traffic and, as a result, business revenue.

You can test your website speed using one of the tools to know if improvements are needed. 89 score and below means your site’s performance needs to be improved. Image optimization and minification of CSS and JS can speed up a website. But as you can see, it is not an easy task. 

Also, hiring skilled web developers who can write quality, optimized code is important. Because it is an almost impossible job to optimize a website that was created by low-skilled web specialists. Re-developing the website from scratch becomes easier, faster, and cheaper in this case.

From Singapore to New York: How Chester Yow Turned Doubt Into Drive

Breaking New Ground in a Foreign Land

For Chester Yow, the decision to leave Singapore, his hometown, wasn’t an excursion but rather a mission. After two years in the military, Chester aimed to challenge his own comfort zone, venturing far away from the familiar into the unknown of a new country on the other side of the world. “I wanted to prove that I can be successful in another country, in another city,” he shares. While it is common that many Asians would like to take the stable route to be near their community, Chester wanted to flip the script and rewrite his story.

Drawn to the fast pace and competitive spirit of New York City (NYC), Chester quickly realized that real estate was made for him—because for a person who doesn’t enjoy 9-to-5 office jobs like Chester, real estate allows the flexibility while maintaining the discipline needed to survive in NY. It is this combination of freedom and responsibility that has become the driving force for him to start building a network from scratch in this city that never sleeps.

Shattering Stereotypes in the Heart of New York

“If you can make it there, you’ll make it anywhere.” It’s a common, inspirational pipeline when speaking of New York. It’s inspiring enough to imply that challenges will always remain—not to bring you down, but to toughen you up. Chester’s no exception. With a heart filled with unrelenting passion and determination, it was still not enough—especially when dealing with racial discrimination and prejudice.

As a fresh-off-the-boat Asian in the U.S., he soon faced the harsh realities here—that discrimination can be both subtle and publicized at the same time. “You do get looked down on as a ‘minority’ at times, and people tend to judge or doubt you faster. I sometimes get, ‘Wow, your English is so good’ (English is the spoken language of Singapore), or ‘Why aren’t you a doctor, lawyer, or accountant?’” he recalls.

Chester faced many challenges during his early days in the States, including racial discrimination and cultural differences. 

But instead of surrendering to the stereotypes, Chester leveraged them as inspiration. “I work harder than the next person, I study harder, I make sure I’m more prepared, I do everything necessary in my power so that there’s no doubt in anyone’s mind to question my capabilities.”

And his effort paid off. By exceeding expectations and proving himself with actual results, Chester is, step by step, changing common misconceptions—not only for himself but also for an Asian working in real estate in New York. Then, even those who doubted him reached out to him for work.

What grounds me is knowing why I work so hard and who I’m working for—my family, my loved ones, my future self 30 years down the road, and my own future family. I’m working hard for them. Having that quiet confidence to keep my head down and keep going is crucial, too.

The Life-Changing $450 Million Development Project

“Tough times don’t last, tough men do”—a quote from my military days that has stuck with me. Ryan Serhant also says, “You are allowed to quit—just make sure it’s on your best day.” You control your own destiny, and building mental toughness is essential to success. Mentorship is crucial for any entrepreneur, and one of Chester’s mentors can be traced back to his military days.

That advice led to a breakthrough in his career. One of the biggest turning points came in 2017, when Chester helped launch a $450 million luxury real estate project in Manhattan. As part of the SERHANT. team, he had the opportunity to bring the project to Ryan Serhant—one of the industry’s most prominent figures—and collaborate directly with his top-tier team.

“That project didn’t just help me close more deals (and earn more), it grew my network with consumers and other top agents, to learn the ropes of new development, and to work and learn closely with Ryan, thus growing my career exponentially,” Chester shared. It was an experience that catapulted his career and opened doors that might’ve otherwise taken years to access.

Staying Rooted on Unfamiliar Ground

As someone who grew up in Asia, Chester was raised with a mindset rooted in caution and logic. “We’re often taught to think of the worst-case scenario, to lead with reason, and to stay guarded and conservative. But that can sometimes come off as negative or dismissive,” he said. Living and working in the U.S. challenged those values and pushed him to adopt a more balanced approach. “I’ve learned not just to be prepared for the worst, but also to lead with optimism, follow my heart, and be vulnerable. Embracing failure and change has been key to my growth.”

That flexibility in mindset has helped Chester adapt and thrive in a fast-paced environment like New York. Even after many years away from Singapore, he’s maintained a strong connection to its culture and community. He regularly attends events and is active in organizations that support Asians in NYC. “There are so many ways to stay connected to being Singaporean and Asian here,” he shared. “I have a great group of friends and partners—we collaborate, support each other’s businesses, and stay rooted in our culture. In fact, 70% of my clients are Asian, and working with them helps me stay connected as well.”

“Work hard, work smart, stay persistent, and block out the noise around you. Find a purpose that gets you out of bed every day and use it as your daily motivation. Hold on to the people who believe in you—and forget the ones who don’t.”

Breaking Boundaries and Making Laughter with Julie Kim

From the Boardroom to the Comedy Club

Julie Kim didn’t begin her career in comedy—she initially followed the stereotypically ‘Asian’ path of stable jobs in academia and office work. Born and raised in Toronto to a Korean immigrant family, her upbringing took place in a tight-knit, two-bedroom apartment above her family’s grocery store. “At one point, there were seven people in the apartment,” she recalls. “And for a solid six or seven years, I slept on the pull-out sofa bed in the living room.”

With multiple degrees under her belt—including a Master’s and two attempts at a PhD—she straddled the worlds of business, education, and motherhood. Amidst the hustle and bustle, there remained a silent passion in her for a creative life. “At first, I wanted to speak well to stand out among a sea of old white men in boardrooms,” she says. “I also wanted to do a difficult, admirable thing. It was a checkbox.”

Julie Kim | Comedian

A Dramatic Shift to Comedy

Julie didn’t quit everything overnight to pursue comedy. She experimented with it while holding multiple stable jobs, contract roles, while also pursuing her PhD, oscillating between full and part-time focus on her studies. But passion has a way of growing, and eventually, she did what she had to—crossing what she describes as ‘a bridge between conventional pursuits and creative pursuits.’ She stepped away from academia, turned down secure opportunities, and entered a world full of uncertainty and creative risk.

However, Julie was no stranger to the industry’s harsh stereotypes. She faced mistreatment and discrimination, navigating everything from blatant racism to sexism disguised as condescension.  “One booker tried to push me out of the scene because I winced when someone tried to make me kiss him against my will,” she shares.  “A few local comics hated or resented me from the start because I didn’t ‘need’ to do comedy—as if they deserved it more because I had other options. It was a different kind of discrimination I hadn’t encountered before, but for sure it taught me to stay far, far away from the bitter ones in this industry.”

Jumping to comedy, Julie Kim’s now one of Canada’s most sought-after comedians.

Despite this, Julie pressed forward like the boss that she’s always been. “I had to learn how to produce and promote my own shows. And that built tenacity,” she says. “Now, I’m centered in my identity. My cultural identity and my confidence in it are central to much of the  success I’ve had in the past few years.”

Today, she’s one of Canada’s most sought-after comedians, performing alongside stars like Ronny Chieng, Atsuko, JR de Guzman, and more as she headlines major comedy clubs across North America. “This is the best time of my life,” she says. 

“I’m having the time of my life. But also, I’m still working on a little scarcity mentality and the feeling of constant survival mode,” she shares. “Part of me really enjoys that and part of me needs a new car and a real vacation.”

Being a Mom on the Mic

Being a mother in comedy isn’t easy—especially when constantly on the road. Julie has faced criticism from all sides: family members, fellow parents, and the weight of societal expectations. ‘I deal with it by blocking people out of my life or turning them into jokes—or both,’ she says with a laugh.

Her journey as a mother isn’t separate from her comedy—it is integral to it. “To do my work well, I need to be grounded, happy, and creative. So I try more and more to take care of myself to be those things,” she reflects. “I think it’s an accomplishment to still be writing and performing after more than a decade of true hustling. It’s taken a lot of grit, perseverance, some audacity, and foolishness.”

Julie Kim’s experience as a mother isn’t separate from her comedy career.

Julie Kim’s list of accolades is stacked: writing and producing Simu Liu’s iconic I Am Canadian monologue at the JUNO Awards, winning a 2023 Canadian Screen Award, and headlining four sold-out Just for Laughs shows in Toronto.  She’s also written for Kim’s Convenience and Run the Burbs, two shows centred around Asian Canadian families that have reached global audiences. 

As she continues to tour across North America, Julie is also working on upcoming television and film projects and producing her new podcast, Bothered. Next, she will prepare for a new 2026 tour of her solo storytelling show called ‘No One Special’ and writing her first book.

Pretty Isn’t Enough: 3 Functional Must-Haves for Your Website

A beautiful website doesn’t guarantee success if it lacks functional design. Here are some functional features that you need to consider for your website.

Loading Time 

Nobody likes waiting, so that means a slow website will significantly downgrade your audience’s experience. Improving your website speed is one of the first things to keep in mind when building a website.

loading-time

Mobile Responsiveness

Your audience won’t always find you on a laptop. With nearly 60% of global web traffic coming from mobile devices, it’s essential to design with phones in mind. Don’t just build for desktops—make sure the mobile experience is just as strong.

mobile-friendly

Clear Navigation

Users should find what they need in 2-3 clicks—anything more feels like ordering a coffee but going through a visa application to get it.
