Performance of the page and loading speed of the website the site

How can I improve the performance of the website? Check out our new post on the blog.

We live in an age where every second is precious. The constant rush and lack of time have made website owners realise the need to optimise their sites for speed. In an environment where users have a choice of several hundred or several thousand other, similar websites, yours must stand out as the best and most appealing. Visitors lose patience after just a few seconds and move on to a competitor’s site. Furthermore, a fast-loading site has a positive impact on SEO, meaning your website can rank higher in search results.

What is website performance?

Website performance refers to the speed at which a website is loaded and displayed in a user’s web browser. It is crucial to the success of your online business. Poor performance, on the other hand, can harm your website’s search engine ranking. Why?

• When ranking websites, search engines take their loading speed into account. A slow website will therefore appear lower down in the results.
• Poor performance leads to a high rejection rate.
• Poor performance can slow down the checkout process, which in turn will lead to a lack of conversions

How can you measure and improve a website’s performance?

Webmasters and developers often use various tools to make it easier to measure a website’s performance. Their aim is to assess user satisfaction. During their research, specialists focus on:

• Reducing the website’s loading time, e.g. by reducing the size of files hosted on the site and reducing the number of HTTP requests
• Improving the website’s usability – that is, loading the elements necessary for the user to interact with the site happens at the start, whilst the rest can load ‘in the background’
• Interactivity and smooth operation of the website – in this case, the developers check the smooth flow of elements, the responsiveness of the website, CTA buttons, etc.
• Performance measurement: accurately measuring website speed and identifying opportunities for optimisation

Core Web Vitals: metrics that measure website performance

Core Web Vitals are metrics that relate to the performance and speed of websites. They are among the most essential elements of a website. Alongside responsiveness, security and an encrypted connection, they form an indispensable part of a well-designed website.

Core Web Vitals can be divided into three specific metrics, namely:

• LCP (Largest Contentful Paint) – measures the time taken to load a page, in seconds, until the first element of the page (the largest block of text or section of an image) appears on the screen. For well-optimised websites, the LCP should be as low as possible.
• FID (First Input Delay) – measures how quickly a website responds to user interaction. It could be said that FID relates to a page’s interactivity.
• CLS (Cumulative Layout Shift) – measures all unexpected layout shifts throughout a page’s entire lifecycle. In addition, the CLS metric assesses a website’s ‘visual stability’, which directly impacts the user experience.

Page load time

Page load time is the period between the user’s decision to visit a website and the display of its full content. To avoid putting users off, this time should be as short as possible. Below you will find information on what to focus on to ensure your website loads efficiently:

• Time to First Byte (TTFB)
  This is a metric that measures when your webpage starts loading. More specifically, TTFB calculates the delay on the web server from the moment a user requests to visit a page until the browser receives the first byte of data from the server. Time to First Byte affects the performance of other metrics.
• First Contentful Paint
  This metric measures the time it takes for the browser to display the first piece of content on a page (e.g. an image, coloured elements, etc.) after the user navigates to the site.
• Time To Interactive (TTI)
  TTI measures the time it takes for a webpage to become fully interactive. It is crucial for reducing session abandonment.

What else might indicate problems with a website’s performance?

Page loading speed and performance are also influenced by other factors, such as the size and file size of the files and multimedia content on the page. Even the smallest error can cost you an increased number of bounce rates. Find out what else you need to look out for to keep users on your site.

• The conversion rate can be calculated by dividing the number of conversions, by the number of tracked interactions. By analysing you will find out how effective your website is and implement the necessary optimisations.
• The bounce rate is a metric that shows the number of users who left your website immediately after viewing it. A high bounce rate can have a negative impact on your website’s search engine ranking and conversion rates.
• The engagement rate is the inverse of the bounce rate. It represents sessions on the website during which the user took a specific action.
• Time spent on the site refers to the duration of a single session. A poor result may indicate that your site is not intuitive enough.
• The average session duration indicates the average length of time a user spends on the website.
• The click-through rate (CTR) shows the number of users who clicked through to your website, divided by the number of people to whom it was displayed, e.g. in search results, an email or an advert.
• The error rate is the percentage of HTTP requests that return error codes out of all HTTP requests over a short period of time. A high error rate indicates that something is wrong with the network infrastructure.
