A couple of weeks ago, Google announced Web Vitals — a new set of metrics to measure the speed and user experience of websites. Last week, Google announced that these metrics will make its way into a core algorithm update as new ways of judging and ranking sites based on the page experience they offer. This update is due to arrive some time in 2021.
UX matters, for real now
In 2010, Google announced that it would take site speed into account while determining rankings. In 2018, Google followed up with the page speed ranking factor in the mobile search results. Now, Google announces a new update that looks at a variety of new or updated metrics — combined with other user experience factors, to form the page experience update.
For years, optimizing the performance of websites mostly meant optimizing for speed. But loading times are only part of the equation and the other part is harder to define and measure. This is about how a user experiences all those optimizations. The site might be fast according to the metrics, but does it feel fast? Thus, it’s high time to take a drastic look at page experience.
According to Google, “Great page experiences enable people to get more done and engage more deeply; in contrast, a bad page experience could stand in the way of a person being able to find the valuable information on a page.”
Enter Web Vitals
Early May 2020, Google announced Web Vitals — a thoroughly researched set of metrics to help anyone determine opportunities to improve the experience of their sites. Within those new metrics, there is a subset of metrics every site owner should focus on, the so-called Core Web Vitals. According to Google, “Core Web Vitals are a set of real-world, user-centered metrics that quantify key aspects of the user experience.”
Each Core Web Vital looks at a specific piece of the page experience puzzle and together they help both Google and yourself make sense of the perceived experience of a site. Core Web Vitals are available in all Google tools that measure the page experience.
The Core Web Vitals will evolve over time and new ones might be added in due time. For 2020, Google identified three specific focal points:
These focal points correspond with three new metrics:
LCP, or Largest Contentful Paint: This metric tells how long it takes for the largest content element you see in the viewport to load.
FID, or First Input Delay: The FID looks at how long it takes for a browser to respond to an interaction first triggered by the user (clicking a button, for instance)
CLS, or Cumulative Layout Shift: This new metric measures the percentage of the screen affected by movement — i.e. does stuff jump around on screen?
As you see, these core metrics don’t simply look at how fast something loads. They also look at how long it takes for elements to become ready to use. The Cumulative Layout Shift is the most forward-thinking of the bunch. This has nothing to do with speed, but everything with preventing a bad user experience — like hitting a wrong button, because an ad loaded at the final moment. Think about how you feel when that happens? Pretty infuriating, right?
Combining new metrics with existing ranking factors
The launch of Web Vitals was noteworthy on its own, but Google took it up a notch this week. Google is going to use these new metrics — combined with existing experience ranking factors, to help with ranking a pages. Keep in mind, Google uses an unknown number of factors to judge sites and rank them. Some factors weigh a lot, but most have a smaller impact. Combined, however, they tell the story of a website.
The new Web Vitals join several existing factors to make up the page experience ranking factors:
Mobile-friendliness: is your site optimized for mobile?
HTTPS: is your site using a secure connection?
Interstitial use: does your site stay away from nasty pop-ups?
Safe browsing: is your site harmless for visitors?
These are now joined by real-world, user-centred metrics, like the LCP, FID and CLS mentioned earlier. Combined, these factors take into account everything a user experiences on a website to try to come up with a holistic picture of the performance of your site, as Google likes to say.
Of course, this is just another way for Google to get a sense of how good your site is and it might be easy to overstate the importance of this particular update. It’s still going to be impossible to rank a site with a great user experience but crappy content.
While the quality of your content still rains supreme in getting good rankings, the performance and perceived experience users have now also come into play. With these metrics, Google has found a way to get a whole lot of insights that look at your site from all angles.
Google page experience update in 2021
Google has often been accused of not communicating with SEOs and site owners. In the past, we have seen many core algorithm update happen without a word from a Googler. Today, however, Google appears more upfront than ever. In the case of the page experience update, Google warns us twice: one with the announcement of the page experience ranking factors and once six months in advance of rolling out the update in 2021.
By announcing this way ahead of time, Google gives site owners, SEOs and developers ample time to prepare for this update. There are loads of new tools to come to grips with how these metrics function and how you can improve your site using these insights. There’s a lot of new documentation to sift through. And you can start right now. Sometime next year, Google will give you a heads up that the update will be rolling out in six months time.
No more AMP requirements for Top Stories
You can find another interesting tidbit regarding the page experience update. Google will no longer require AMP for getting your news pages in the Top Stories section. Now, any well-built, Google News-validated site can aim for that top spot. Page experience will become a ranking factor for Top Stories, so your site better be good.
New page experience tools? You got it!
Google went all out for to get every site owner to adapt to the page experience changes. New or updated tools help you get the insights you need. They also help you to make sense of what it all means.
