Berlin / San Mateo, November 29, 2021 – New research from Searchmetrics suggests around 50% of the top 100 most visible¹ websites on still fail to deliver a “good” page experience on desktop as defined in the search engine’s Core Web Vitals update which finished rolling out in August 2021. And 44% of the top 100 websites fail on mobile.

As of October,, and as well as social sites such as, and were among the major brands that are still unable to meet all three minimum thresholds for good website performance and usability set out under Core Web Vitals according to the analysis. And fashion and travel are the worst performing verticals.

The data comes from the newly launched Core Web Vitals Monitor section on the Searchmetrics website. Updated every month, this provides an analysis of the Core Web Vitals performance of the top 100 most visible domains on (Google US), with monthly benchmarks for eight key industry segments (B2B, Dictionary/Reference, Electronics, Fashion, Finance, Healthcare, Media/News and Travel).

What are Core Web Vitals?

Google’s Core Web Vitals benchmarks help website owners assess real-world web user experience in three areas: how quickly the content on a page loads; its interactivity (the time taken to respond to a visitor’s first interaction, such as clicking on a button or a link); and its visual stability (does the layout or content jump around). These three measures are officially known as First Contentful Paint (FCP), First Input Delay (FID) and Cumulative Layout Shift (CLS) respectively. In the Core Web Vitals update they were combined with other existing signals which Google uses to measure the quality of the page experience meaning they now have an influence on Google rankings.

How the top 100 most visible websites perform

The positive news according to Searchmetrics’ analysis is that the proportion of top-performing domains which satisfy Google’s requirements is increasing over time. In January 2020, only 22% of the desktop top 100 and 28% of the mobile top 100 were able to pass the Core Web Vitals tests. By October 2021, this increased to 50% on desktop and 56% on mobile.

For LCP (the time taken for the largest image or text block to become visible when the page first starts loading) the average time among the top 100 in October is 2.43 seconds on desktop and 2.48 on mobile (both just under Google’s minimum requirement which is 2.5 seconds). However, 36% of the top 100 on desktop and 33% of mobile still fail to meet this minimum requirement.

For CLS (which measures the extent to which elements on a page jump around while it is loading), 24% of the top 100 on both desktop and mobile failed to pass the minimum requirement. A “good” score according to Google is below 0.1 and the average score was just a little over this (0.11 on both desktop and mobile).

Most websites tested by Searchmetrics were found to pass the test for FID (which measures interactivity). However, the company notes that because of difficulties in gathering accurate data, experts are not able conduct a meaningful analysis for this metric².

Tom Wells, VP Strategy from Searchmetrics said: “The Core Web Vitals update was Google’s way of encouraging websites to improve the quality of the online experience they deliver. But the data suggests that even some of the biggest brands have not completely solved their user experience challenges. While they continue to rank highly in spite of this, it’s important to remember that the page experience has wider implications especially for eCommerce brands.”

Delivering a user-friendly experience where pages load quickly, respond to input and in which dynamic content doesn’t jump around, is going to help reduce eCommerce bounce rates and abandoned shopping carts, for example, while being good for conversions and return visits.

Fashion and travel perform worse than other verticals

The data suggests eCommerce sites in categories such as fashion and travel on the whole perform worse for Core Web Vitals than all the other verticals included in the analysis.

For example, only 24% of the top 100 most visible fashion and apparel websites pass Core Web Vitals on desktop and just 16% on mobile. And for the top 100 in travel only 20% pass on desktop and 21% on mobile. By contrast B2B and Healthcare sites perform the best, with 60% and 59% of top domains in these sectors passing all 3 Core Web Vitals tests on desktop respectively (51% of the top B2B sites and 63% of the top Healthcare sites pass on mobile).

The average LCP for the top travel sites is 3.37 on desktop and 3.66 on mobile (outside Google’s minimum requirements for a good experience of 2.5 seconds. Similarly in fashion top 100, the average LCP for on desktop is 2.8 seconds and 3.31 on mobile.

Tom Wells, VP Strategy at Searchmetrics continued:

Fashion and travel were found to be the worst performing segments in terms of Core Web Vitals. Part of the explanation is that websites in these sectors – and eCommerce generally - are typically image-heavy and frequently feature dynamic elements such as ad banners.

“Healthcare websites tend to be more informational with less focus on dynamic content while B2B websites seem to strike a good balance between content delivery, user experience, and website performance. Social media websites typically focus on their app delivery – often accessing these apps via a web browser is quite slow, which explains the poor performance of some of them in terms of Core Web Vitals,” said Tom Wells.

¹A note on how Searchmetrics measures search visibility

Searchmetrics measures search performance for websites using its SEO Visibility score. The company monitors the organic search results of millions of keywords which it uses to calculate the SEO Visibility score. The SEO visibility score for a web domain is based on data such as:

  • The number of times a domain appears in the search engine results pages (SERPs) across the keyword set
  • Its prominence within those SERPs (a higher ranking equates to a higher visibility score)
  • The competitiveness of the keyword (higher search volumes equate to a higher visibility score)

It is important to remember SEO Visibility is only an indicator of visibility that comes from a website’s organic search channel.

² In practice, there is not enough user data for a meaningful analysis of FID. FID requires a user to interact with a page for this metric to be recorded. Often this doesn’t happen and results in a 0 being recorded (around 64% of the time) which explains the very low average FID values. Even in Google CrUX dataset covering 8.4 million domains, over 93% of domains were recorded as having a “good” FID which shows this problem does not improve with a larger sample size.

About the data

This report combines Searchmetrics analysis based on SEO Visibility with CrUX Core Web Vitals performance data.

  • Data collection
    Core Web Vitals performance data is taken from the Chrome User Experience Report. This report updates its data on the second Tuesday of every month for the previous month. Data is aggregated across an entire domain, not on the page level. CrUX data is based on real user interactions – this is sometimes called field data.
  • Ranking top domains
    The top 100 domains are determined based on Searchmetrics’ SEO Visibility² metric that analyzes total expected traffic based on all keywords and their SERP positions that a domain ranks for. This data is device and country specific.
  • Defining industries
    For the industry breakdown, a keyword set was defined for each of the 8 industries. This keyword set was tracked in the Searchmetrics Suite and a traffic share analysis was performed to establish the top 100 domains by industry and device.
  • Core Web Vitals Metric Explainer
    All metrics shown in this report are the 75th percentile. This is the same as the metrics Google displays in PageSpeed tests under “Origin Summary”. For example if a domain has an LCP of 2.4 seconds, then 75% of all visits to that domain across the entire month were quicker than 2.4 seconds.
