Core Web Vitals is a hot topic in the SEO world right now. For those not in the know – Core web vitals are quality signals that Google are placing more significance on to help deliver a better user experience. From mid June 2021 a page experience update is to be rolled out, and by August 2021 websites rankings will change to take into the core web vital metrics.

At the time of the rollout the delayed Euro 2020 competition kicked off so the inner geek in me wondered if there was a core web vitals competition who would win?! Each of the 24 teams competing in the Euros have had their official club websites ranked on their performance of their core web vitals.

See how the tournament played out. Spoiler alert it didn’t come home for England…

Group Stages
The rules in the group stages are as follows:

  • 1 point for a good LCP score – The largest contentful paint measures loading performance and should occur within 2.5 seconds of when the page first starts loading. Anything 2.5 seconds is deemed as good.
  • 1 point for a good CLS score – The cumulative layout shift which measures visual stability should be 0.1 or less.
  • 1 point for a good FID score – The first input delay which measures interactivity, should be 100 milliseconds or less
  • 1 point for a good FCP score – The first contentful paint measures the time which the first text or image is painted. 1.8 seconds or less is a good score
  • 1 point for passing a mobile friendly test
  • 1 point for a overall mobile website performance score of 60 – according to Google Page Speed Insights

Each websites is scored using field data in PageSpeed Insights, and points scored as per the above to rank the four teams in each group.

Group Stage Results:

Group A:

Wales ( come out winners of group A with 5 out of 6 available points. Scoring well with LCP, CLS, FCP and FID. The overall website score is 56 – just short of getting the 6th point.

Disappointment for the Italians with an early exit due to an LCP of 3.5 seconds, CLS of 0.28 and a performance score of just 17/100.

Turkey were the only side to not have a mobile friendly site – you hate to see it!

Group B:

Another shock in group B with favourites Belgium getting knocked out due to a very high LCP of 5.6 seconds, and a low overall performance score.

Denmark scored 6 out of 6 available points but still have some room for improvement should they want to progress further…

Group C:

The biggest shock of the tournament so far with North Macedonia performing above all expectations, scoring 5 out of the 6 points.

The Netherlands have put in a solid performance with just an improvement needed with their FID.

Group D:

Look away now England… the has had a shocker. Scoring just 1/6 due to the website being mobile friendly but failing on all other core web vitals metrics.

Scotland fared much better (for a change!) and was enough to see them through to the next round. Czech Republic and Croatia both seeing strong performances.

Group E:

Another shock with Spain taking an early flight home. Their LCP and FCP just wasn’t strong enough to see them compete.

A much closer group which should see some good ties in the next round.

Group F:

They said this was the group of death, and it certainly was. France and Portugal were close to second with France clinching it with a better CLS and FID.

Hungary need to review their mobile site before the next tournament; they were one of three to fail a mobile friendly test.
