How to Analyse Best Website Performance

When it comes to website performance, everything boils down to Page Experience.

Since 2021 when the Google core web vitals have been rolled out, adept shift on user experience has been recognised and given priority by search Engines. And this is just the beginning.

So, whether it’s page experience for Google or user, websites need to strike a balance between the two for ultimate website performance.

From performance monitoring to testing, keep reading to understand all the how to’s related to website performance.

How and Why do Website Performance Matters?

Website performance plays a critical role in user experience, search engine rankings, and overall website success.

So, what do you mean by website performance?

Website performance refers to the speed, responsiveness, and overall user experience of a website.

It encompasses various factors such as page load times, server response times, and how quickly the website responds to user interactions.

Why and how does website performance matters?

  • Website performance is important for user experience

A fast-loading website can greatly improve user satisfaction and engagement.

Studies show that visitors are more likely to leave a website that takes more than three seconds to load, leading to high bounce rates and reduced conversions.

In contrast, a fast-loading website can improve engagement, increase time spent on site, and lead to higher conversion rates.

  • Website performance is a critical factor in SEO

Search engines prioritize fast-loading websites in their rankings, which can lead to higher visibility, more traffic, and ultimately more conversions.

A slow-loading website can have a negative impact on search engine rankings and reduce overall website visibility.

  • Website Performance impacts website conversions

A website that loads quickly and functions smoothly can improve the overall user experience and increase the likelihood of conversions.

On the other hand, a slow or unresponsive website can reduce trust and confidence in a brand, leading to reduced conversions and revenue.

How to Measure Website Performance from Google’s point of View?

This question is tricky as there are a lot of performance metrics that need to be considered but we’ll be focussing on the latest and most important Core Web Vitals.

Since June 2021 till today, Core Web Vitals continue creating hype in the SEO and web development industry and are the heavily searched topics.

Let’s discuss in detail by taking an example on how CWV help in website performance monitoring.

Google primarily focuses on these three pillars for measuring website performance.

  • Loading Speed (How fast content appears on screen?)
  • Response Time (Time taken to respond to user input)
  • Visual Stability (the stability of the web elements while loading)

To measure these three metrics, three unique parameters are defined which are known as Core Web Vitals. Let’s have a look.

Largest Contentful Paint (LCP)

LCP measures the time taken to load the largest piece of content on a webpage.

This can be an image, video, or block of text. LCP is important because it impacts the perceived loading speed of a webpage.

A fast LCP means the user can see the main content of the page quickly, which improves user experience and engagement. A slow LCP can lead to frustration and high bounce rates.

Good LCP score: less than 2.5 seconds

Bad LCP score: more than 4 seconds

Let’s understand with an example:

Let’s understand with an example
Refer the picture. The first content that loads on the webpage is called FCP or First Contentful Paint but it may or may not be the largest.

If you check the second last screen. It holds a space for the image which is the largest content of the page. This is called LCP.

The time to load this LCP should be under 2.5 seconds for a better user experience and good website performance.

Website performance testing for LCP

To measure LCP, you can use various web performance testing tools. Here’s a step-by-step guide on how to measure LCP using Google’s PageSpeed Insights:

  1. Go to PageSpeed Insights.
  2. Enter your website’s URL and click “Analyze.”
  3. Wait for the analysis to complete.
  4. Scroll down to the “Largest Contentful Paint” section.
  5. Check the “Performance Score” for LCP. The score ranges from “Good” to “Needs Improvement” to “Poor.”
  6. Check the “LCP” value in seconds. This value represents the time it takes for the largest piece of content on your webpage to load.

Alternatively, you can also use Google’s Chrome DevTools to measure LCP. Here’s how:

  1. Open Google Chrome and go to your website.
  2. Right-click anywhere on the webpage. Select “Inspect.”
  3. Click on the “Performance” tab.
  4. Click on the “Reload” button to start recording.
  5. Wait for the recording to complete.
  6. Check the “Summary” section to see the LCP value in seconds.

By measuring LCP using these tools, you can get a better understanding of your website’s performance and identify areas for improvement.

First Input Delay (FID)

Experiencing a delay after clicking any button on the website while it is still loading? This is First Input Delay or FID.

FID is one of the most critical and essential website performance metrics that measures how long it takes for the browser to respond to a user’s first interaction with the webpage.

This interaction could be a tap, click, or keypress, scroll, browsing action etc., and a faster response time leads to a more responsive webpage.

Delays in responsiveness can cause frustration among users and can make your website feel sluggish.

With websites becoming more complex and powered by JavaScript, it’s vital to focus on FID to speed up the process between getting content on the screen and making it interactive.

The FID measures all interactions that happen during the loading of the page, making it an essential metric to optimize for a better user experience.

Good FID score: less than 100ms

Bad FID score: more than 300ms

Website performance testing for FID

Something which you need to note is that you directly cannot predict on FID if there is no user interaction.

The Google search console will directly prompt “no data” found. Google needs data from the real user or what we call it as field data. Lab data or simulated data will not work here.

Usually, to improve this course it’s the JavaScript which is the prime culprit behind the low FID scores. Undoubtedly JavaScript help us to build some amazing interactions but results in slowing of the websites due to its complex code.

JavaScript is a client-side script, so the entire burden comes on the browser and the browser takes time to respond until it has finished executing JavaScript.

So, by working on the JavaScript code and optimising it or removing unused JavaScripts help you improve on your scores. Thereby improving your overall page experience and website performance.

Google’s PageSpeed insights is an awesome performance testing website by Google. You can check your scores there or from Google search console and Google’s Chrome DevTools.

Cumulative Layout Shift (CLS)

You must have often have seen websites loading the text content first and thereafter, the entire section shifts down suddenly as an image needs to be displayed.

This visual shift is irritating and frustrating for the users as the users have already started interacting with the first loaded content and did not expect anything else would disrupt their browsing.

This is Cumulative Layout Shift or CLS and it measures the amount of visual layout shifting that occurs on a webpage as it loads.

Reason of visual shifting?

  • This can happen when images, ads, or other elements load after the initial content, causing the page to jump around.
  • Other reason could be, there are no designated/dedicated places set for ads, text and images which directly impacts the visual stability of a webpage.

A low CLS means the webpage is visually stable and user-friendly, which improves user experience and engagement. A high CLS can lead to frustration and poor user experience.

Good CLS score: less than 0.1

Bad CLS score: more than 0.25

Checking website performance for CLS
Same tools are used for all web core vital metrics. You need to check that score and the performance rating should indicate green colour. If it’s red or yellow, it means the website needs to improve on that.
