Classement webperf JDN - mai 2023

It's time to take a look at this month's webperf rankings of the most visited sites in UK.

We are thrilled to launch our very first UK Speed Ranking. This ranking is divided into several categories: the 50 most visited sites, e-commerce sites, media sites, and travel sites. But before diving into the results, it's crucial to remind why fast-loading websites are key to online success.

As a reminder, the score obtained for the sites presented in this article is calculated using a methodology based on CrUX (Chrome User Experience Report) data. In order to give the best evaluation of each site's mobile web performance, we based our calculations on the weighting of the Lighthouse score :

  • FCP represents 10% ;
  • LCP represents 35% ;
  • CLS represents 25% ;
  • INP represents 30%.

CrUX provides an overall assessment of the Core Web Vitals metrics for each site analysed. This metric is calculated by taking the 28-day rolling average of the 75 percentile performance throughout the month. The overall performance score is determined by a weighted average of the scores for each metric. This score, rated out of 100, is used in the rankings below (so it is not the PageSpeed score that is used in the rankings below).

Why is Speed Crucial ?

Studies show that website performance directly impacts user experience, conversion rates, and revenue. According to Google, 53% of mobile site visitors leave a page that takes longer than three seconds to load. For UK e-commerce sites, this statistic is particularly concerning given the intense market competition.

A Deloitte study reveals that a 0.1-second improvement in mobile site speed can increase conversion rates by 8.4% for retail sites. These figures highlight the importance of prioritizing loading speed to stay competitive.

In June, we observed several small changes in positions, reflecting both optimization efforts and some regression. 

This month the top of the speed rankings remains strong with all metrics in the green:

  • GOV.UK leads the pack with an INP of 108 ms.
  • Wikipedia follows close behind with an INP of 104ms.
  • Indeed rounds off the top three with an INP of 137 ms.

The actors with the best performances

Several sites have shown significant improvements, climbing the ranks with enhanced web performance metrics:

  • BT.com has surged up 8 places to the 24th position, making slight improvements in LCP, INP, and a notable 10-point reduction in CLS.
  • The Independent has climbed 6 places to the 22nd spot, with enhancements in CLS and LCP contributing to its rise.
  • Santander UK has moved up 3 places to break into the top 10 at the 9th position.
  • Marks & Spencer has also advanced 3 places to the 19th, with a significant 44-point improvement in INP.
  • Additionally, Asda, B&Q (Diy.com), Spotify, and Ikea UK each gained one spot, illustrating ongoing efforts to enhance their web presence

These improvements are the fruit of constant efforts to optimise the system, with particular attention paid to Interaction to Next Paint. Yes, those with a good FID don't necessarily have a good INP! FID only takes into account the first interaction, whereas INP enables interactivity to be assessed over the entire browsing time. The efforts made by these players to improve their web performance metrics are not only beneficial for their rankings, but also crucial for offering a quality user experience, reducing bounce rates and increasing engagement on their platforms.

TOP 50 : Challenges in the Rankings

Not every site could maintain or improve their standing. Here are the sites that struggled this month:

  • Argos dropped 5 places to 26th. Interestingly, there was no significant degradation in its performance metrics. The slip can be attributed to competitors stepping up their optimization efforts more aggressively.
  • Express fell 4 places to 31st.
  • Disney Plus descended 3 places to 21st. The site experienced a slight worsening in its LCP, potentially impacting user experience with slower content loading.
  • Zoopla also moved down 3 places to 27th, suffering from declines in both LCP and INP, highlighting the need for continued focus on optimizing visual and interactive performance.
  • Other notable platforms that each lost 2 places include : Etsy, BBC, Amazon, News.sky and Daily Mail.

72% of the players analysed do not have a green CLS, a metric that has a strong impact on UX. As a reminder, a high CLS can lead to a frustrating user experience, with page elements moving around unexpectedly.

72% of the players analysed do not have a green CLS, a metric that has a strong impact on UX. As a reminder, a high CLS can lead to a frustrating user experience, with page elements moving around unexpectedly.

33% do not have a green INP, the metric that replaced the FID on 12 March 2024. The INP records the latency of all interactions throughout the lifecycle of a web page. The highest value of these interactions - or close to the highest for pages with many interactions - is recorded as the INP of the page. A low INP indicates that the page is reliably responsive at all times.

Here are the e-commerce rankings, for which web performance is a business and SEO issue.

E-commerce: Average of vital Core Web

Notable Improvements :

  • Iceland has made an impressive leap, gaining 7 places to reach the 22nd position. 
  • Marks & Spencer has ascended 2 places to claim the 9th spot, thanks to an improvement in their LCP by 105 points and INP by 44 points. These enhancements likely contributed to a better and quicker user experience, aligning with customer expectations for swift and responsive online shopping.

Every millisecond of improvement or degradation can influence a site's position in a competitive environment. In a market where user experience is directly linked to performance, maintaining optimal speed metrics is essential. These regressions remind e-commerce sites of the need for constant vigilance and optimisation. To remain competitive, these sites must regularly assess and improve their web performance to avoid losing ground to their competitors.
