Core Web Vitals vs. Page Experience: How They Are Different

Google has launched new parameters for web experience called core web vitals. The purpose of web vitals is to enable website owners and SEOs to understand how a page performs according to Google’s standards.


In contrast, page experience or page quality rating evaluates user satisfaction from a specific search session based on the different factors that affect user dissatisfaction from a given site’s pages. In addition, it also assesses if there are any spam indicators related to the input query terms used to access any given webpage. If any business wants such professional services, they can always take assistance from an SEO company India who can provide them with an SEO package, if they find it complicated to perform such tasks.

Core Web Vitals: How They Are Different From Page Experience

The data-driven Core Web Vitals measures several aspects of mobile and desktop screen sizes such as time spent on a particular site within viewport making use of machine learning techniques.


In contrast, the Page Experience Rating evaluates a site based on the following range of indicators: spam, low-quality content, slow page speed, broken links and misused rich snippets. In addition to these factors, there are also other parameters such as demotions or lower rankings which might result from the manipulation of search results through paid means of promotion.


Although they both affect website performance from Google’s point of view, Core Web Vitals and Page Experience Rating serve two different purposes and are granted differently across devices.

Core web vitals as a subset of page experience rating

It is built to measure web pages at a large scale while the other measures specific site pages. The other difference between core vitals and page experience rating is found in how Google uses it to affect website performance. The former affects all results across devices while the latter only affects page-specific results without ranking changes.

What page experience measures?

The Page Experience Rating measures different factors based on whether a website is using a mobile or desktop viewport. For Websites that use Mobile Viewports, the following range of indicators are assessed:


  • Spam: Site content has been obfuscated through compression and/or encryption
  • Low-quality content: The majority of pages in the indexed site contains irrelevant content and keywords
  • Slow page speed: The site takes more than 5 seconds to fully load for 50% of users.
  • Broken links: The majority of internal links are broken leading to missing subpages/content
  • Misused rich snippets (Reviews, Ratings, etc.): Title and meta description used without author/publisher permission


All these factors affect website performance because Google uses them to measure the quality of individual website pages and how they affect user satisfaction.

How do you use it to improve your site’s performance?

Google evaluates several factors such as page content, keywords, links, and reviews/ratings to determine a webpage’s quality and relevance during a given search session. Google uses this information to provide relevant, high-quality results that satisfy users’ intent. The higher the rating, the more likely it is for a specific webpage to appear on top of its corresponding SERP.


When we say “top”, we mean appearing at the first page or section because Google uses core web vitals and page experience rating in determining which websites appear wherein SERPs: spammy sites will rank lower than others while those with high-quality pages that satisfy users’ intent will rank higher than others.

What is it used for? How does it affect your rankings in SERPs?

Google uses Core web vitals to measure the quality of an entire site rather than specific web pages. This means that you do not need to focus on individual web pages or sites to improve their performance in search results when using core vitals measurement. Instead, it only takes into account certain page parameters such as response time, JS integration, and its relevance with user search terms.


On the other hand, page experience rating targets specific web pages by measuring their content’s relevance for a given query term. As mentioned earlier, the latter affects search session- results through demotions or lower rankings.

Wrapping up!

Page experience is a holistic metric that contains several factors that contribute to user experiences such as page speed and mobile responsiveness. On the other hand, core web vitals is just one parameter Google uses for measuring site-related performance which also affects search session results. With this information in mind, you can now improve your website’s performance and better focus on making relevant content and web pages without having to worry about specific factors used by Google to determine a webpage’s quality and relevance and where it will rank in SERPs.


As a website owner, you need to take care of everything you publish on your site because Google can demote or rank lower SEO-related work if it deems that a webpage is of low quality. Make sure to use page experience rating properly and improve your overall website performance with the help of core web vitals. In addition, make sure to improve the content of specific web pages that you want to rank higher using page experience rating.
