February confirms a very stable top of the ranking, with Gov, BBC and Ikea maintaining their leadership thanks to consistently strong user experience across loading, interactivity and stability.
Several sites improved their performance this month: notably PayPal (+7), Gumtree (+6) and Office (+5) showing how targeted optimisations can quickly increase the share of users enjoying a good experience.
On the other hand, some platforms experienced significant regressions. National Lottery (–41) recorded the most dramatic drop after major degradations across all metrics, while Skyscanner (–7) and NY Times (–7) also lost ground due to declines in loading or layout stability.
Across sectors, e-commerce remains relatively mature, media sites load fast but still struggle with interactivity, and travel continues to lag behind, with only 4% of sites achieving a PX Index above 90.
👉 The key takeaway: Web performance leadership is no longer about hitting technical thresholds: it’s about maintaining a good experience for the largest share of users, consistently over time.
It’s time to take a look at this month’s webperf rankings of the most visited sites in the UK.
For more than ten years, we have been analysing the performance of the most visited websites on a monthly basis. These rankings, built on Chrome User Experience Report (CrUX) data and Google’s Core Web Vitals, have become a benchmark for assessing the market’s maturity when it comes to user experience.
Until now, websites were ranked using a score based on whether they met Google’s recommended thresholds. This approach played a key role in structuring market priorities and in democratising web performance as a discipline.
Over time, however, a limitation became clear:
a website can technically meet all Core Web Vitals thresholds while still exposing a significant share of its audience to a degraded experience.
At Fasterize, we have chosen to put the user experience at the centre of measurement. Performance can no longer be evaluated purely as technical compliance, but as a reality actually experienced by users throughout their journey.
This conviction led us to evolve our historical score into the Performance Experience Index (PX Index).
From February 2026 onwards, all of our rankings are now based on the PX Index.
A truly high-performing website should not only work well for a statistical majority, but deliver a good experience for all its users.
Le Performance Experience Index (PX Index)
The PX Index is scored from 0 to 100 and measures the real share of users benefiting from a good experience on a website. It is based on real-world user data from the Chrome UX Report, and on all the key metrics that shape the user journey : from server response time to on-screen interactions.

The overall score is calculated as a weighted average of the percentage of users having a good experience, with each metric weighted according to its real impact on perceived performance:
The full methodology is detailed in this article.
With this new methodology, rankings take on a different meaning.
The goal is no longer simply to display the 75th percentile values to check whether a site “passes the thresholds”, but to show the percentage of users who actually enjoy a good experience (i.e. above the threshold).
As a result, a percentage greater than or equal to 75% means that the metric is validated according to Google’s “Good” threshold, since its 75th percentile meets the requirement.
We’re excited to unveil the new edition of our UK Speed Ranking ! Each month, we analyse mobile web performance across:
- 50 of the most visited websites in UK
- 30 major e-commerce platforms
- 20 leading media websites
- 20 key players in the Travel sector
But before diving into the results, let’s remind ourselves why fast-loading websites are critical to online success.
Why speed matters ?
Speed isn’t just technical : it’s strategic ! 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.
Let’s dive into the February 2026 rankings and analyses.
Top 50 : Webperf ranking of the top 50 most visited websites in the United Kingdom
February confirms a remarkably stable leadership at the top of the ranking, with the same trio continuing to dominate thanks to consistently strong user experience across loading, interactivity and visual stability.
At the same time, several sites made notable progress through targeted optimisations, while others experienced significant regressions that quickly impacted their ranking.
🏆 TOP 3 LEADERS
Gov.uk (→ #1) retains the top position with a PX Index of 95, continuing to set the benchmark for reliable digital services. With 97% of users experiencing fast loading, 93% smooth interactions, and 98% stable layouts, the platform delivers one of the most consistent user experiences in the UK web ecosystem.
BBC (→ #2) remains firmly in second place with a PX Index of 94. The site maintains excellent loading performance and exceptional visual stability, ensuring a comfortable reading experience even during periods of intense news consumption.
Ikea (→ #3) completes the podium once again with a PX Index of 93. The retailer continues to demonstrate strong UX maturity, balancing fast loading, responsive interactions and stable layouts across complex product pages.
🌟 NOTABLE IMPROVEMENTS
- PayPal (+7 → #36) One of the most significant improvements this month.
PayPal records gains across all metrics, with +10% more users experiencing fast loading, +5% enjoying smooth interactions, and +6% benefiting from stable layouts. Interactivity now reaches the green threshold, improving overall usability. - Gumtree (+6 → #21) A clear improvement in visual stability, with +7% more users experiencing stable layouts. This optimisation reduces layout shifts during browsing and significantly improves perceived page quality.
- Office (+5 → #23) improves its loading performance, with 75% of users now benefiting from a fast loading experience, allowing the LCP metric to reach the green threshold.
- Vinted (+4 → #28) records small but consistent improvements across several metrics, leading to a gradual but meaningful gain in ranking.
- Temu (+3 → #9) continues its upward trajectory in the Top 10. While the underlying metrics remain largely stable, the platform benefits from the relative stagnation of competitors, consolidating its position among the leaders.
These sites reflect ongoing efforts to improve user experience, which will likely continue to positively impact user experience and engagement. These improvements are the result of consistent efforts to optimize their systems, with particular attention paid to INP. It’s worth noting that having a good FID does not necessarily mean having a good INP! FID only measures the first interaction, whereas INP assesses interactivity throughout the entire browsing session. The efforts made by these players to improve their web performance metrics are not only beneficial for their rankings but are also crucial for providing a quality user experience, reducing bounce rates, and increasing engagement on their platforms.
📉 CHALLENGES IN THE RANKINGS
National Lottery (–41 → #48) The most dramatic drop of the month. The site experiences a severe degradation in user experience, with the PX Index falling by 33 points. The deterioration affects all key metrics:
- 63% of users now experience poor visual stability
- 17% more users face degraded interactivity
- 48% of users who previously experienced fast loading now face slow pages
This sharp decline suggests that the site may currently be experiencing major technical issues, or potentially undergoing structural changes that severely impact performance.
- The New York Times (–7 → #29) loses several places due to reduced visual stability, with 15% more users experiencing layout shifts, affecting reading comfort.
- BT (–4 → #27) also records a decline driven by visual instability, with 13% more users experiencing degraded layout stability, introducing friction during navigation.

📊 Top 50 — experience overview

Across the Top 50, the overall picture remains relatively stable, but the data highlights a persistent gap between fast loading and truly smooth user journeys.
On average:
- PX Index: 78
- 19% of users still experience slow loading (LCP outside the green threshold)
- 28% encounter degraded interactions, reflecting ongoing challenges around responsiveness (INP)
- 20% face layout instability, which can disrupt navigation and reading comfort
Looking at threshold validation across the ecosystem:
- 14% of sites achieve a PX Index above 90
- 38% of sites now validate all three Core Web Vitals (up from 34% last month)
- 54% meet the interactivity threshold (INP) (slightly down from 56%)
- 78% maintain good visual stability (CLS) (down from 80%)
👉 Key takeaway:
While the share of sites passing all Core Web Vitals is increasing, interactivity remains the main friction point for users, with more than a quarter of sessions still experiencing slow or unresponsive interactions. Maintaining performance over time therefore requires continuous monitoring and targeted optimisations.
Loading speed and layout stability are now largely under control for most major sites.
Interactivity remains the main differentiator, and the metric that most clearly separates leaders from the rest.
Here are the e-commerce rankings, for which web performance is a business and SEO issue.
E-commerce : Webperf ranking of the top 30 most visited sites in the United Kingdom
February confirms a very stable leadership among UK e-commerce platforms, with the same three players maintaining their positions thanks to consistently strong user experience across loading, interactivity and layout stability.

📊 E-commerce experience overview

At sector level, e-commerce continues to show solid foundations, particularly in loading performance and layout stability. However, interactivity remains a structural challenge.
On average:
- PX Index: 76
- 20% of users still experience slow loading (LCP outside the green threshold)
- 33% encounter degraded interactions, highlighting persistent responsiveness issues
- 20% experience layout instability, which can disrupt browsing or checkout flows
Looking at threshold validation:
- 10% of sites achieve a PX Index above 90
- 37% of sites validate all three Core Web Vitals
- 80% meet the loading threshold (LCP) (up from 73% last month)
- 43% meet the interactivity threshold (INP)
- 73% meet the stability threshold (CLS) (down from 80% last month)
Most e-commerce sites now load fast and remain visually stable, but interactivity is still the main bottleneck. Improving how quickly pages respond to user actions is now the clearest lever to stand out, reduce friction, and protect conversion during high-pressure periods like sales.
👉 Key takeaway:
Most e-commerce platforms now load quickly and remain visually stable, but interactivity remains the main bottleneck. Improving how quickly pages respond to user actions is becoming the clearest lever to reduce friction, improve engagement and protect conversions during high-intensity periods such as sales.
Media : Webperf ranking of the top 30 most visited sites in the United Kingdom
February confirms the strong maturity of UK media platforms in terms of loading speed, with most sites delivering fast access to content. However, maintaining smooth interactivity and consistent visual stability remains a challenge for a significant share of publishers.

Travel experience overview

Travel continues to lag behind both e-commerce and media sectors, in terms of both maturity and consistency.
On average:
- PX Index: 77
- 22% of users experience slow loading (LCP outside the green threshold)
- 27% encounter degraded interactions, highlighting persistent responsiveness issues
- 24% experience unstable layouts, affecting navigation and booking flows
Threshold validation highlights the sector gap:
- Only 4% of sites achieve a PX Index above 90
- 23% of sites validate all three Core Web Vitals (up from 19% last month)
- 69% meet the loading threshold (LCP)
- 35% meet the interactivity threshold (INP) (up from 27% last month)
- 58% meet the stability threshold (CLS) (down from 61% last month)
👉 Key takeaway:
Travel remains the least mature sector in terms of user experience. While several platforms are making targeted progress, interactivity continues to be the main bottleneck, and too many users still face friction during key moments of the booking journey. Reducing this friction will be essential for travel platforms looking to compete with more UX-mature sectors.
Performance is no longer determined solely by a single technical value, but by the ability of websites to consistently deliver a good experience to the majority of users.
Reaching the “green” zone once is no longer enough.
The PX Index highlights a more demanding reality: true web performance is a capability, not a snapshot.
It requires:
- Continuous monitoring of real-user experience, not lab metrics
- The ability to detect early drifts before they impact large portions of the audience
- Fast, repeatable execution to correct issues without slowing down business teams
In increasingly competitive environments, improving the percentage of users with a good experience means:
- Less friction in critical journeys
- Higher trust and engagement
- Stronger SEO/ GEO signals
- A durable competitive advantage
The sites that lead the rankings are not just faster : they are better organized to maintain performance over time.
