Page Speed: How It All Started

Early period (1996-1998)
The history of this concept can be traced back around 30 years. The appearance of “page speed” is tightly related to the emergence of the Internet. When the use of the Internet became more and more popular, website creators faced the need to improve their user’s experience and ensure the fastest loading of pages and their content.

1998 became another important year in the history of page speed. Could you guess why? The thing is that Google, the most popular search engine giant, entered the market. People started to search a lot of information, and the speed of search, as you know, depends on the general page speed.

Development of new web technologies and emergence of the instruments to assess page speed (2000-2010)
In this period, developers and other tech experts were focused on creating the solutions that make it possible to measure page speed and optimize it. That's how WebPageTest appeared. It was one of the first instruments that helped developers assess site load speed and enhance the performance of their websites.

In 2009, Google presented its own solution called Google Page Speed that not only measures the speed of loading but provides effective recommendations on its improvement as well. In the following year, Google made the official statement regarding page load speed. Starting from it, page speed became one of the most important factors that impact search engine rankings.

Mobile Internet and the need of websites to adjust to its peculiarities (2011-2020)
With the growth of popularity of smartphones and other gadgets, the use of mobile Internet came first place. According to the new trends, Google updated its algorithms, boosting the websites that were adjusted to the mobile Internet specifics. Mobile SEO site speed became a new challenge for tech experts. In this period Google presented its Accelerated Mobile Pages (AMP) and additional updates to Google Page Speed. Moreover, Google integrated its core metrics to assess page load speed. They were called Core Web Vitals. Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift were defined as crucial factors that set the quality of general user experience and page speed for SEO.

Recent years (2021-till now)
Google Search Console and other analytical platforms appeared, making measurement of load time of website more convenient and simple. Tech experts started to use AI to analyze page performance, users behavior, and other important characteristics, providing recommendations on how to improve page speed for SEO and general customer experience. Moreover, some AI instruments demonstrated their ability to automatically optimize page speed. React, Angular, and Vue frameworks integrated new approaches and features to improve page load speed. Another prominent event was the creation of the 5G Internet. It boosts page speed significantly, however, if the website page is too large and not optimized properly, there can still be some problems with page loading speed. So the question “how to make page load faster” is still challenging and relevant nowadays.

In today's fast-paced digital world, a slow-loading website can drive away potential customers. Don’t let this happen to you! Discover how to enhance your page speed and significantly boost your SEO with insights from Mykola Breslavskyi. Learn about key tools, crucial metrics, and professional strategies to ensure your website loads quickly and efficiently.

Why Your Website Needs PageSpeed Optimization

As we have already mentioned in the previous paragraph, page load speed is of crucial importance for your website. Let’s take a closer look at statistics that will definitely make you think of how to make a page load faster:

  • In average, website loads in 8.6 seconds in mobile (Tooltester).
  • The pages that are in top of Google ranking loads in around 1.65 seconds (bloggingwizzard).
  • More than 80% of online users stated that they want websites to load in less than 3 seconds (WebFX). Taking into account this fact, 40% of users claimed that they will leave the website if it will load longer.
  • The loading speed of online shops is extremely important for 64% of users. They stated they will switch to another shop if they have to wait too long till the page loads (hobo).
  • Around 80% of online shop visitors said that they will never visit the online shop again if the experienced poor page load speed (HUCKABUY).

In general, page speed optimization is important for the following reasons:

  • It defines general user experience. If you don’t want to make your website visitors annoyed and want to ensure smooth and convenient interaction with your website, you need to take care of how fast the content is loading and how fast the website provides responses to the users requests.
  • Better conversion = more income. The faster your website loads, the more chances that the user will implement the target action. And vice versa, if your customers have to wait too long, it’s completely predictable that they will leave the website and your bounce rate will grow.
  • More organic traffic. Google identifies pages with great load speed and places them in higher SEO ranking. It means that more people can see and visit your website. So you will have more potential customers.
  • Increased customer loyalty. Great experience with your website stimulates your visitors to return and make more target actions.
  • Optimization of your resources. When your website loads fast, it reduces the load on servers and hosting costs.

Page Speed: Key Metrics and Tools for Measurement

Now let’s discuss in more detail on what metrics you should focus to ensure the best loading page speed:

  • Largest Contentful Paint (LCP) it’s time when all page content (images, videos, text, etc) become visible. The most optimal amount for this indicator is 2,5 seconds.
  • Cumulative Layout Shift (CLS) it’s about unexpected layout movements that can happen during page loading. The more stable your page layout is, the better.
  • Time to First Byte (TTFB) how much time does it take for a browser to receive the first byte of data from the server? If more than 200 milliseconds, you should think of improvements.
  • First Input Delay (FID) this indicator helps to define the duration of the delay between the user’s action (for example, tapping the button) and server’s response.
  • First Contentful Paint (FCP) characterizes how much time is needed for the browser to show the first part of content after the page loading.

The following tools will help you measure these indicators correctly:

  • Google PageSpeed Insights it’s free of charge, created by Google, able to evaluate both mobile and desktop website versions and provide valuable insights.
  • GTmetrix is popular due to its detailed analytics and reports that are easy to compare. Also it provides great visualization and ability to pick different locations for testing.

Make Page Load Faster: Technical Aspects

Now let’s dive into the Q&A session with the Perfsol Co-Founder and CTO Mykola Breslavskyi. He has extensive experience in site load speed optimization, so knows the drill and is more than happy to share his experience!

1. What are the primary factors affecting our website's loading speed?

The site loading speed is affected by:

  • the number of libraries used on the client side.
  • the size of images and fonts, as well as the strategy of their loading.
  • the number and optimization of styles.
  • the use of third-party scripts that can temporarily block the display of the page.
  • pages with a large amount of content will take longer to load than those with a small amount.
  • presence/absence of caching.
  • location of the server where the site is hosted.

2. How do you prioritize the optimization tasks for improving page speed?

You can start by implementing best practices, such as using the built-in Image, Script, Link components in NextJS. The next step is to check whether we need all the libraries that we send to the client side. The next step is to improve the code (code splitting, proper use of server and client components, etc).

3. Can you explain the difference between First Contentful Paint (FCP) and Largest Contentful Paint (LCP)?

FCP is a quantity that shows how much time has passed before the first element appeared on the screen, and LCP is the time when the largest element presented on the screen appeared.

4. How to reduce page load time in JavaScript?

  • Remove unnecessary/optional libraries.
  • If possible, postpone the loading of heavy libraries.
  • Divide the code into logical parts so that the browser can load them separately.
  • Postpone loading images and elements that are not on the first screen.
  • Optimize styles.
  • If possible, remove scripts that block the flow.

5. How does image optimization impact page load time, and what techniques do you recommend for it?

Using images of the appropriate size and quality greatly affects the loading speed, as images are usually the largest part of the page. To automatically optimize the image, NexetJS has its own Image tag, which helps to show the visitor exactly the image that is suitable for their device.

6. What are the best practices for leveraging browser caching?

Caching is an important component of optimization, as it allows you to significantly increase the display speed when you visit the site again. At the same time, it is important to find the golden mean between user-friendliness and the frequency of content updates on the site.

7. How do you approach reducing server response time?

To do this, it is advisable to choose a server that will be as close as possible to your main visitors, as well as to optimize requests. Make them as simple and small as possible.

8. Can you explain the benefits of using a Content Delivery Network (CDN) for our website?

As we mentioned previously, website speed is affected by the distance between the client and the server. A CDN allows you to reduce this distance by duplicating the code on several servers and choosing the one that is closer to the client.

9. How do you handle render-blocking resources in our site's CSS and JavaScript?

Blocking resources should be reduced in size and their number should be minimized. For example, the code for displaying the captcha can be loaded when the visitor starts interacting with the form.

10. Can you discuss the importance of lazy loading for images and videos?

For most cases, this approach is best practice. The only exception is the images on the first screen, which should be loaded as soon as possible.

11. How do you ensure that third-party scripts don’t negatively impact our site’s performance?

You can check the impact of third-party scripts on website speed using Google PageSpeen Insights and Lighthouse, as well as by running a code analyzer. Large libraries that are sent to the client will negatively affect the site speed.

12. What methods do you use to optimize the critical rendering path?

First, we need to minimize critical resources, as well as minimize the impact of CSS. Focus on the effective management of JavaScript as it can block page rendering. Then compress assets, integrate lazy loading, and prioritize the loading process.

13. Can you explain how reducing the number of HTTP requests can enhance page speed?

Each request takes time to execute and process the result, so a large number of requests will slow down the website. On the other hand, using streaming, you can divide the page into logical parts that will receive data not simultaneously, but gradually, which will have a positive effect on the speed of the site display, as the page will come to the client in parts.

14. How do you address issues related to Time to Interactive (TTI)?

All the recommendations we discussed above will come in handy. In the context of TTI, the parameters of blocking (and its reduction) and the correct distribution of code between server and client components will be especially important.

15. How do you stay updated with the latest trends and techniques in PageSpeed optimization?

At conferences dedicated to SSR frameworks, a lot of attention is always paid to website optimization and new tools that appear for this purpose.
