What Is Website Performance and How Does It Benefit Your Business?

Usually, two perspectives shape the importance of website performance and what it stands for. One is relevant for businesses that wish to make revenues on par or better than their investment return. The second is for digital marketers to be more interested in the website’s ease of use and loading speed. However, when assessing overall website performance, these perspectives merge and become more than the sum of their parts. The adjoining infographic helps explain how:

 Website Performance

Consider this: if your website is challenging to navigate, has slow page loading times, and needs clear CTAs or other visual cues to guide the prospect, then you not only suffer from cart abandonment but also decreased SERPs and lower organic traffic. Now, wouldn’t that be a bummer? 

Therefore, you must ensure your website is optimized for cross-device functionality since anything slower than lightning-fast rapidity will result in similar issues. Considering how most users navigate the internet through their mobile devices, this would spell worse woes for your online enterprise. With that cleared, let’s check out the benefits of website performance optimization. 

What Are The Benefits of Website Performance Optimization?

Every organization implements web performance optimization as a standard practice to improve website performance. A successful website's performance is the business’ foundation, primarily as it determines whether or not a user would be interested in it. Go through the pointers below to analyze the importance of ideal website performance:

  • Ease-of-use & navigability
  • Higher engagement
  • Enhanced brand visibility through increased online traffic
  • Boosts search engine rankings
  • Increased revenue
  • Seamless learning experience for educational purposes
  • Overall user satisfaction and maximum impact

Tools to Measure Website Performance & Speed

Now that you have understood the importance of website performance from a commercial perspective, you must learn how to improve web service performance. Measuring website performance via a website speed test ensures a smooth and enjoyable user experience. With dwindling attention spans and skyrocketing competition, providing a seamless website experience can be your best bet in the digital age. You can take advantage of the web performance optimization framework below to get an overview of the process:

Tools to Measure Website Performance & Speed

Several comprehensive performance metrics and web speed testing tools are available which marketers and developers can use for their assessment. Let’s take a look at some of those tools. 

1. Google PageSpeed Insights

Google’s PageSpeed Insights is a fantastic tool to measure your website’s performance according to Core Web Vitals’ tenets. It provides a score from 0-100 as a quantifiable audit of your site’s performance, highlighting bottlenecks and other issues you must immediately address. 

If you encounter performance issues related to Core Web Vitals assessment, you must know how to improve web service performance from their perspective. But to do that, you must know what they are. Simply put, Core Web Vitals is a set of standardized metrics by Google that analyze and report a website’s user experience. Although meant for developers, all site owners can employ these metrics (page loading performance, interactivity, and visual stability) to get objective insights into user perception. The core tenets of web vitals are tabulated as follows:

  • Largest Contentful Paint (LCP) : To provide a seamless user experience, you must measure the LCP within the first 2.5 seconds after the web page starts evolving and loading so that customers can find the most crucial content on your internet site straight away without any delay. A speedy LCP can also assist in improving your internet site’s leap price and average engagement. Therefore, optimizing your internet site’s loading pace is critical to getting a quick LCP.

  • First Input Delay (FID) : One key metric for measuring interactivity is the First Input Delay (FID), which measures the time between a consumer's first interaction with your website (including clicking a button) and your site's reaction. Ideally, your site's FID should be less than 100 milliseconds. However, note that beginning in March 2024, Google will change FID with a new metric called Interaction to Next Paint (INP) as a Core Web Vital.

  • Cumulative Layout Shift (CLS) : Visual stability is critical to ensuring a high-quality user experience for your website, where a Cumulative Layout Shift (CLS) rating is used. This  calculates the number of sudden format shifts that occur throughout a website's loading. A valuable personal experience is accomplished with a CLS score of much less than 0.1 seconds; because of this, the site experiences minimum sudden layout shifts, resulting in a robust visual experience for the user.

  • First Contentful Paint (FCP) : First, Contentful Paint (FCP) is a metric used to measure the speed at which visitors can view content (textual content, pictures, video, etc.) on your website. It calculates the time taken from the start of your page load to when any content appears on the screen. A low FCP time is ideal as it contributes to a superb user experience. The faster your page loads, the sooner and better your traffic understands it.

  • Interaction to Next Paint (INP) : Interaction to Next Paint (INP) is a critical web performance metric that reveals how fast a website responds to consumer movements, including clicking a button or typing in a search field. This metric is critical for websites that require everyday user interactions, as delays in response time can cause frustration and result in a poor user experience.

  • Time to First Byte (TTFB) : The term TTFB refers to the responsiveness of a web server and is measured in milliseconds. It differs from HTTP request TTFB since it involves the timeframe taken for DNS lookup, TLS, SSL connection, and server reaction time for an HTTP request; TTFB only measures the server response time for an HTTP request.

Google provides several tools for common usage that users and developers can use to assess and optimize website performance. A list of such tools and their measurement capability is outlined in the adjoining diagram:

Core Web Vitals

Moreover, Google’s PageSpeed Insights can audit websites across different devices to recommend actionable insights. For instance, it can ask you to reduce server response time, ensure that the images have recommended height and width, and to avoid large layout shifts. 

Apart from Core Web Vitals, some other performance metrics that you should consider are:

Website performance metrics

2. GTmetrix


GTmetrix is another trusted tool to optimize website performance with servers worldwide. It provides recommendations for the top issues that need to be fixed immediately, apart from issues consuming the most resources. That’s not all; just like Google PageSpeed Insights, GTmetrix lets you know whether your website passes the Core Web Vitals parameters. Furthermore, you can check browser and device combinations to assess your website’s performance. 

3. IBM Instana Observability

IBM Instana Observability

One of IBM’s premium offerings to optimize website performance is Instana Observability- a tool that allows instant and intelligent issue detection and resolution. The tool boasts a comprehensive dashboard, analytics, and “Smart Alerts” to notify you about real-time lags, such as JavaScript errors and HTTPS status codes. Furthermore, users get context-dependent traceability and integration with other log management and network monitoring tools. 

4. Pingdom


Pingdom is a renowned name among all tools to optimize website performance measurement tools, particularly for its feature to shoot real-time alerts if your website performs below the optimal standards. 

5. MaxCDN


You can test the speed of your website at 14 various locations across the world using MaxCDN's new performance testing tools. Additionally, it allows you to compare the performance of two domains, which helps test various conditions or evaluate how well your website performs compared to a rival. In addition, the HTTP Speed Test allows you to compare the first and last bytes of two websites.

Improving Website Performance while Optimizing For Speed

Optimizing website performance is a multidimensional process incorporating various technological tweaking to improve speed, user experience, and overall efficiency. A lot goes into fine-tuning a website perfectly, but specific broad strokes are crucial. 

For instance, your goals on the front end include reducing the size of assets such as photos, CSS, and JavaScript files to improve loading time. Lazy loading, which defers the loading of non-essential items until needed, helps speed up the first-page load. 

Furthermore, prioritizing crucial rendering paths ensures that essential content is provided quickly, resulting in a more responsive and engaging user experience. Depending on the overarching goals of the developer, marketer, or business owner, the website optimization process may vary. However, a guided roadmap can help ease the strategy-construction process, as shown in detail below:

Website optimization strategies

A holistic strategy that addresses both front-end and back-end aspects is critical to unlocking the full potential of website optimization for improved performance. Check out the standard optimization framework matrix to get an idea. 

Web delivery layer

Geographical areas also become nagging irritants but are less likely to be considered a technical hindrance. So, although these problems seem far too challenging, they are likely not. Furthermore, we shall touch upon all the best practices of a standard website optimization policy in this blog for the ease of our readers. Therefore, let us walk through some processes you can use to optimize your website. 

1. Perform A Comprehensive Audit

This crucial first step determines the course of action for all your website optimization efforts. Performing a comprehensive audit for website optimization involves systematically examining various elements to assess and detect different areas of improvement. Refer to the different types of website performance audits in vogue to get an idea

Perform A Comprehensive Audit

You can perform the analysis using tools such as Google PageSpeed Insights, GTmetrix, or IBM Instana Observability, discussed above. Using a website speed report can also be a fantastic starting point. Ultimately, the more cross-platform data you have about your site’s functionality, the better.

3. Evaluate Your Current Hosting Provider

Have you ever wondered whether your website’s current hosting provider could be a source of ongoing and potential speed issues? Well, now is your time to put on your thinking cap and sniff out the source of your website’s speed lags. Your hosting provider’s geographical location, physical infrastructure, and overall network connection bandwidth may be to blame. You may use a website bandwidth checker to get an insight into the connection’s bandwidth. Moreover, you can refer the infographic below get an overview of website hosting services commonly available today.

Evaluate Your Current Hosting Provider

4. Optimize Your Images

Did you know that images can take up to 21% of a website’s weight, according to Kinsta? Well, it must have dawned on you just how vital image weight can be in website performance. However, several image compression tools can come in handy for your needs, especially with their tailored features. Let’s kook at some of the most popular online image compression tools:

Optimize Your Images

CompressNow is as valuable a tool as it gets for converting any image file type into .jpeg format. It works well for pre-made and customizable image compression dimensions. 

Regarding optimization and compression, consider compressing other frivolous file types that may secretly slow down your website and impact its loading time. The most commonly used compression type is Gzip, which is used by almost 60% of all websites, per data from W3Techs. Some other forms of compression are shown in the diagram below:

Optimize Your Images

Furthermore, the compression methods employed by other content types to improve website site speed test can be understood from the following graph.

Limit Your Font Use

To enhance your performance, you might want to reduce the number of fonts you use, otherwise you end up dragging your website’s resources. Check out the graph below to understand how different fonts affect loading times.

5. Limit HTTP Requests

Limiting HTTP requests is a crucial aspect of website optimization, directly affecting the website’s performance and associated user experience. Every HTTP request a web page initiates causes latency since the browser must retrieve resources like scripts, stylesheets, and images from the server. To reduce this latency, web developers often combine CSS or JavaScript files into one, reducing the total number of requests. We shall discuss these strategies in more detail in the upcoming sections. Meanwhile, you can check the diagram below to understand the factors responsible for HTTP latency.

 Limit HTTP Requests

To limit the number of HTTP requests, you can consider HTTP caching as a go-to strategy. This is a process for storing web resources such as HTML pages, scripts, stylesheets, and images at several different places on the network to avoid repetitive transfers that ultimately lead to latency. This increases the efficiency of online applications and overall user experience.

Thus, when a user visits a web page, their browser can determine whether it already has a locally stored copy of the requested file. Unless it is already expired, the browser can retrieve from the cache rather than send a new request to the server. Check this blog to learn more about browser caching. Additionally, you can refer to the image below to get an overview of the concept. 

 Limit HTTP Requests

6. Cash-in On Caching

Several Content Management Systems (CMS) and browsers already support caching for easy file retrieval. However, it benefits your business to go the extra mile and extend the caching timeframe through the CMS settings. This can be applied for static content types in your website, such as logos, images, downloadable files, scripts and stylesheets. Confused? Check out this blog to learn more about caching’s role in website performance optimization.  

Additionally, you can take the help and guidance offered by third-party caching plug-ins providing all-in-one optimization features. Some of the plugins for WordPress (since it is the most widely used CMS out there)  are:

WP Rocket

WP Rocket is WordPress's most potent and impactful caching plugin. This tool comes power-packed with essential features such as page caching, GZIP compression, lazy loading of images and videos, cache preloading, CSS and JS file minification, eliminating render-blocking JavaScript resources, removing unused CSS, and scheduling automatic database cleanups. That’s not all; thanks to its default settings, you can expect to fine-tune your Core Web Vitals and improve your web performance upon activating this plugin.  

WP Fastest Cache

This tool comprises comprehensive features that enable users to apply permutations and combinations of several tactics involving minifying HTML and CSS files, eliminating render-blocking JavaScript files, lazy loading, cross-device cache optimization, etc. Therefore, this tool is fantastic for deriving clean and efficient code for your website and pages. 

SiteGround Optimizer

This expert-attested WordPress plugin boasts over 1 million active installations. The features prove its delivery, which is robust enough for a free plugin service. Some features include dynamic caching, Memcaching, file-based caching, WordPress Heartbeat optimization, GZIP compression, image compression, and front-end cleanup. Moreover, this plugin is best for non-technical users, considering the easy steps and guidelines the plugin provides. 

7. Combine JavaScript and CSS Files & Eliminate Render-Blocking

Developers can dramatically improve page load speeds by combining CSS and JavaScript files. This process, called file concatenation, not only improves the first-page load speed but also benefits subsequent visits because cached files may be retrieved faster. Furthermore, reducing file size through compression techniques ensures that the consolidated files are transmitted faster over the network, contributing to an enhanced overall experience.

Moreover, combining JS and CSS files facilitates asynchronous loading. By placing non-essential scripts toward the end of the HTML document or using asynchronous loading techniques, vital content can be rendered quickly, offering quicker access to the web page’s fundamental functionality. Enabling such optimization tactics allows developers to strike a balance between speed and functionality, resulting in websites that promise faster load times with a rich user experience. You can take the help of tools such as GTmetrix to combine or minify (literally, decrease the size of) large JavaScript and CSS files. 


Or, you can minify CSS and JS manually by:

CSS and JS manually

However, if your website is extremely complex or uses HTTP/2, then you should rather not combine your JS and CSS files lest you end up with a larger combined file that further drags your website’s processing resources. Moreover, HTTP/2 is better equipped to handle concurrent connections unlike HTTP/1.1. Take a look at the example below to understand how combining large scripts and stylesheets can potentially harm rather than benefit your website on HTTP/2.


Speaking of enhancing website functionality, consider eliminating render-blocking CSS and JavaScript for improving load speed. Render-blocking are files which must be mandatorily downloaded, parsed and executed upon being encountered by the browser. Such files impact page load speed without necessarily enhancing the user experience. Refer the adjoining image for greater conceptual clarity. 

render-blocking resources

Such render-blocking resources affect the browser’s Main Thread, and the more they are served, the slower the page loading becomes. Thus, large scripts and stylesheets become a hassle in optimal website experience. 

8. Adopt A Mobile-First Approach

More people than ever before access the internet via their mobile devices. Refer the infographic below to understand the importance of mobile-first design.

Adopt A Mobile-First Approach

Now that you know the importance of mobile-friendly design for your website's performance, consider what you need to do to achieve one. While getting started, you or your developer might run into the following issues:

Issue that developers face

While fixing the issues outlined above, revamping your mobile website to include the following features can also be considered.

9. Embrace CMS Database Optimization

Employing a CMS's built-in website performance optimization features can help you overcome the complexity of manual optimization strategies. Thus, with features like built-in CDN, you can save time, energy, and resources through automated optimization techniques. 

On the other hand, page speed optimization can enhance your CMS database performance. However, you must be wary of using excessive plug-ins that could increase your database speed. You must also 

  • delete old or unused data
  • use indexes and queries to improve retrieval speed
  • identify slow or problematic queries using EXPLAIN and ANALYZE commands

Consider JanBask’s Sitecore CMS consulting services to get started with your CMS-specific issues. 

10. Determine & Fix Your DNS Speed

TTFB is linked to DNS response time in that the longer it takes for the DNS Server to respond, the slower TTFB takes to register. FYI, TTFB or time to the first byte is the time required by a browser to receive the first byte of data from the web server, demonstrated by the image below:

DNS Server to respond

You can use DNS assessment tools to detect issues with DNS and resolve them simultaneously. An example of such a tool is OpUtils, whose intuitive user interface makes it easy to resolve DNS issues. 


Embrace Asynchronous Loading

Several files on your webpage load in a sequence, allowing elements to appear only when one file after another is loaded successfully. However, this results in a slower page loading speed which ultimately impacts user perception involving website performance. This is where you might want to consider asynchronous loading to rev up your website’s performance. While synchronous loading depends on the sequence-wise loading of files for the element to render, the asynchronous version involves the simultaneous loading of essential files while relegating the non-essential ones to load later. 

Embrace Asynchronous Loading

You can avail several plugins to help get started with your asynchronous loading process, some of which are:

  • AutoOptimize 


This plugin is fantastic for minifying, combining, and optimizing CSS and JS files. But, this tool really shines when it comes to optimizing uncombined JavaScript files. Its cornucopia of features ensures that there is something for everyone when it comes to website optimization. 

  • Async JavaScript 

Async JavaScript

Suitable for optimizing WordPress websites, Async JavaScript helps users to eliminate their render-blocking JS scripts in above-the-fold header content while also allowing them to “async” or “defer” other specific files. These functions help you to optimize your website performance at will through improved page load speeds.

Speaking of website performance-optimizing plugins, you would want to choose only the best, wouldn’t you? Check out this blog to learn the best CRM plugins for WordPress. Similarly, you would want to eliminate other poor-performance plugins that drag your website down. The general rule of thumb is, that you should only employ the fastest and latest version of plugins that you install.
