i. Understanding the Importance of Page Load Speed

A. A Quick look at the concept of page load

Page load time is the amount of time it takes for a web page to fully load. Measured in seconds, it’s one of the indicators of a web page’s performance, and a slow one can hurt user engagement and, consequently, business performance.

How Is Page Load Time Calculated?

Page load time is calculated from the moment you click on a link or type in a website’s address to the moment when all the elements of the page are displayed on the screen. To make this request happen, the browser and the server go through the following cycle:

• The user sends a server request. This can be clicking on a URL or a link to load a new page, or get a page with a list of products from a simple “table calendar” search from an e-commerce website.

• The server processes the browser’s request.

• The browser receives data/information from the server for the requested page. (Note: The time between sending a request to a server and receiving the first byte of data is called the time to first-byte (TTFB). Google uses this metric to measure how fast a website loads.)

• The page’s content is processed, loaded, and displayed by the browser, and the requested page is fully loaded.

Several factors are taken into consideration when measuring the web page load time. Website owners can affect some of these, while others such as the user’s location, device, browser and internet connection are beyond their control, yet still affect the page load time. For example, the same web page can load differently on different browsers (e.g., Firefox, Chrome) and devices (e.g., desktop vs. tablet vs. mobile), and in different locations.

Why Is Page Load Time Important?

Your business bottom line is significantly influenced by your website’s page load time, as consumers desire speedy, easy-to-navigate websites. Here’s how:

• SEO and Search Engine Ranking:  Google uses web page loading time as a direct ranking factor, influencing a page’s position in the search results. A slow loading page can hurt your site’s SEO by increasing the bounce rate and decreasing the average session time, or by dropping the organic traffic from the search engines.

• User engagement and customer satisfaction:  Slow page load times also affect how users see and interact with your website. Over 70% Of Customers say that page speed impacts their likelihood to purchase. Consequently, close to half of them are less likely to buy and return to the slow website in the future.

• Bounce Rate:  If your page speed is poor, customers may not wait for it to load and leave instead to search for a faster website. According to Google Research the probability of a user leaving a website (bounce rate) increased by 32% when it took 1-3 seconds to load a page, by 90% when it took 1-5 seconds, and by 123% when it took more than 10 seconds to load a page.

• Business aspects:  Keeping page load times low is vital to enhance conversion rates and sales revenue. Every second lost is an opportunity lost. Studies show that 40% of users leave a website that takes longer than 3 seconds to load. Furthermore, for every additional second a website takes to load, a 7% drop in conversion rates may be expected.

B. A Comparison Metric For Page load speed efficiency

When comparing the efficiency of page load speed across different websites or web applications, several metrics can be used to assess and quantify performance. One commonly used metric is the Page Load Time (PLT), which measures the time it takes for a webpage to load completely. PLT provides a straightforward comparison of how quickly different pages load and is often the most important metric for user experience. However, there are other complementary metrics that can provide a more comprehensive evaluation of page load speed efficiency. Here are a few key metrics to consider:

• First Contentful Paint (FCP): FCP measures the time it takes for the first piece of content to be rendered on the screen. It indicates how quickly users can see the page's primary content. FCP is particularly useful for evaluating perceived performance and providing a faster visual feedback to users.

• Time to Interactive (TTI): TTI measures the time it takes for a page to become fully interactive. It considers the time needed for all scripts, stylesheets, and other resources to load and execute, allowing users to interact with the page seamlessly. TTI is crucial for assessing the usability of interactive elements and ensuring a responsive user experience.

• Document Object Model (DOM) Content Loaded: DOM Content Loaded measures the time it takes for the HTML document to be fully parsed and the DOM tree to be constructed. It represents the point at which JavaScript can start interacting with the page's content. DOM Content Loaded is particularly relevant when evaluating the performance impact of JavaScript execution.

• Time to First Byte (TTFB): TTFB measures the time it takes for the first byte of data to be received from the server. It represents the server's responsiveness and network latency. A lower TTFB indicates a faster initial response and can contribute to improved overall page load speed. 

• Resource Size and Number of Requests: In addition to time-based metrics, it's essential to consider the size of resources (e.g., HTML, CSS, JavaScript, images) and the number of requests made to retrieve those resources. Minimizing file sizes and reducing the number of server requests can significantly improve page load efficiency.

C. Why and How page load speed efficiency is essential to UX Performance

• User Satisfaction: Users expect fast and responsive websites. Studies have shown that users are more likely to stay engaged and satisfied when pages load quickly. A slow-loading website can lead to frustration, reduced engagement, and higher bounce rates, negatively impacting the overall user experience.

• First Impression: Page load speed is often the first interaction users have with a website. It forms their initial impression of the site and sets the tone for their entire browsing experience. A fast-loading page creates a positive first impression, instilling confidence in the website and its content.

• User Retention and Conversion: Slow-loading pages can deter users from staying on a website and completing desired actions, such as making a purchase, signing up for a service, or submitting a form. Improved page load speed increases the likelihood of user retention and conversion, leading to higher engagement and better business outcomes.

• Mobile User Experience: With the rise of mobile browsing, page load speed is even more critical. Mobile networks often have limited bandwidth and higher latency, making fast-loading pages essential for a smooth mobile user experience. Mobile users are more likely to abandon slow-loading websites, underscoring the importance of speed optimization.

• SEO and Search Ranking: Page load speed is a ranking factor in search engine algorithms. Search engines, like Google, prioritize fast-loading websites to provide a better search experience for users. Improved page load speed can positively impact search engine visibility and organic traffic, ultimately benefiting the overall UX and business success.
