“That store looks amazing. Maybe we should give it a try!”

You walk in. No one’s around to take care of you. Crew seems busy. No, they aren’t even around. You somehow grab what you liked, but that’s it. Billing seems to be swamped.

That’s the ultimate guide to losing a customer in under 5 minutes. 

Now, let’s project the same situation to a website visitor.

You enter a site; the UX is miserable, you have to scroll 15 times to the right and 12 times to the left to read a line, it takes forever to load, the text isn’t legible… 

You bounced. 

The website’s ranking anyway.

Oops! Here’s some bad news! 

Google Page Experience Algorithm update! And May 2021 is your date.

What is Google Page Experience Update?

According to Google,

Page experience is a set of signals that measure how users perceive the experience of interacting with a web page beyond its pure information value. It includes Core Web Vitals, which is a set of metrics that measure real-world user experience for loading performance, interactivity, and visual stability of the page. It also includes existing Search signals: mobile-friendliness, safe-browsing, HTTPS, and intrusive interstitial guidelines.


The update is slated to release in May 2021. 

You could call this one the guardian of website experience sorts. If you wish to climb the ladder of SERPs, page experience is going to be one of the important areas where you’ll have to score well. 

Let’s pick up the magnifying glass now and get down to business.

What are the Core Components of Google Page Experience Update?

The Google Page Experience signals is a mix of the following signals: 

  • Core Web Vitals
  • Mobile-friendliness
  • Safe-browsing
  • HTTPS-security
  • Intrusive interstitial guidelines.

Core Web Vitals

Core web vitals are user experience signals that are measurable and throw insights into the real-world user experience on a website. Currently, the three main components of core web vitals signal include: 

  • Loading 
  • Interactivity
  • Visual Stability

Largest Contentful Paint is a metric that measures how long it takes for the largest component or element to load. It reports the rendering time taken for the most sizable image or text block to load within the viewport. 

What is a good LCP score to have? 
For a great user experience, the website should have an LCP in the limits of 2.5 seconds. Anything that’s above 4 seconds is bad. 


First Input Delay is a measure of the time taken for the browser to respond to an interaction that’s initiated by a user, for instance, to click a button, or browse a link. 

From the first time at which the user interacts with a page to which the browser finally reacts to that action is what FID finds out. 

What is a good FID score to have? 
An FID score of less than 100 milliseconds ensures a great user experience for website visitors.


Cumulative Layout Shift is a metric that shows the percentage of the screen that moves based on the stimuli of a user, in essence, user behavior & movement. 

According to Web.Dev

CLS measures the sum total of all individual layout shift scores for every unexpected layout shift that occurs during the entire lifespan of the page.
What’s a good CLS score to have?
A website must aim to get a  strive to have a Cumulative Layout Shift score that’s less than 0.1.

Mobile Friendliness

Mobile browsing accounts for half of the website traffic worldwide. Can we blame Google for wanting website owners to just make the sites mobile-friendly for an enriched user experience?

Most of the sites are mobile-optimized by now. But in case you have second thoughts, run checks to ensure the same for your domain. 


Hypertext Transfer Protocol Secure is a safety protocol for internet communication that safeguards the privacy and integrity of any data that’s transferred between a user and a website. Google encourages websites to secure the HTTPS status for their domain to protect a user’s connection.

The best way to go about it is by getting a valid certificate from a trusted CA or Certificate Authority. Post that, redirect your HTTP URLs to the secured one. Here’s Google’s detailed article about the same. 

Safe Browsing

It’s important to ensure that your website doesn’t contain any malware or malicious entities, nor does it promote any deceptive content. Here’s Google’s article about the same.

Non-Intrusive Interstitials 

In simple terms, this is a measure of how easy to access is the content on the site. According to Google, here are some of the ways in which it becomes difficult for a user to access the information.

  • A pop-up which engulfs the entire screen and leaves no room for the content to be visible to users. 
  • A standalone element that has to be discarded by the user to proceed browsing the site. 

How does Google Page Experience affect SEO?


Google says in cases where multiple pages have similar exceptional content, Page Experience becomes a key decider on controlling the visibility on SERP.


A poor user experience stands in the way of a person to find what they’re looking for. The website could actually contain the essentials, however, a poor UX directly results in them bouncing to another site. Mission failed, right there. 

Coupled with the increase in the number of owners referring to Lighthouse & Page Speed Insights, Google Page Experience update comes as a no brainer, sooner or later. 

However, having websites or pages that adhere to these guidelines and offers the best experience doesn’t necessarily mean they would rank and rule at the top.

At any given day, this doesn’t overrule having great content or relevant information that drive value to users. 

What about AMP & Top Stories?

In mobile, pages were required to have an AMP version ready to stand a chance to be featured in the top stories. However, after Google Page Experience update rolls out, this no longer becomes a mandatory criteria. 

Any website, irrespective of having an Accelerated Mobile Pages version to its pages still could compete to make it to the Top Stories. In fact, the update would become a catalyst for ranking.
