Google Page Experience Update (Core Web Vitals)

Google Page Experience Update (Core Web Vitals)

In May 2021, Google introduced the Page Experience Update, focusing on Core Web Vitals as a pivotal ranking factor in Google Search. This significant update emphasizes the importance of user experience and aims to provide users with search results that lead to websites offering a seamless and enjoyable browsing experience.

What Are Core Web Vitals?

Core Web Vitals are a set of specific factors that Google considers important in a webpage’s overall user experience. These metrics are:

  1. Largest Contentful Paint (LCP): This measures the loading performance of a webpage. Google recommends that websites should aim for an LCP of less than 2.5 seconds.
  2. First Input Delay (FID): FID assesses the interactivity of a webpage. Websites should target an FID of less than 100 milliseconds to ensure that the page is responsive and interactive.
  3. Cumulative Layout Shift (CLS): CLS evaluates the visual stability of a webpage. Websites should strive for a CLS score of less than 0.1 to minimize unexpected layout shifts.

Impact on SEO Practices

The Page Experience Update has significantly impacted SEO practices, shifting the focus towards enhancing user experience:

On-Page SEO:

  1. Optimizing Loading Performance (LCP): To improve LCP, optimize server response times, leverage browser caching, and optimize images and scripts. Implementing lazy loading for images and videos can also help improve loading times.
  2. Enhancing Interactivity (FID): To optimize FID, minimize JavaScript execution time, optimize event handlers, and ensure responsiveness to user inputs.
  3. Improving Visual Stability (CLS): To enhance CLS, ensure that all images and ads have dimensions specified in the HTML or CSS to prevent layout shifts. Implementing animations and transitions carefully and avoiding inserting new content above existing content can also help improve visual stability.

Off-Page SEO:

  1. Optimizing Server and Hosting Configurations: Enhance website performance by optimizing server and hosting configurations, implementing content delivery networks (CDNs), and leveraging browser caching to reduce loading times and improve overall user experience.
  2. Improving Website Design and Layout: Implement responsive web design, optimize the mobile-friendliness of the website, and ensure a consistent and intuitive user interface and navigation to enhance user experience and satisfaction.

Why Did Google Make It?

Google’s primary goal with the Page Experience Update is to encourage website owners to prioritize user experience. By integrating Core Web Vitals as ranking factors, Google aims to provide users with search results that lead to websites offering a seamless and enjoyable browsing experience. This focus on user experience is in line with Google’s commitment to rewarding websites that offer high-quality, relevant, and user-friendly content.


The Page Experience Update (Core Web Vitals), launched by Google in May 2021, emphasizes the importance of user experience as a crucial ranking factor in Google Search. Adapting to these new metrics and focusing on optimizing website speed, interactivity, and visual stability is essential for businesses and SEO professionals to maintain and improve their visibility and rankings in search results. Prioritizing user experience not only helps in achieving better search engine rankings but also enhances user satisfaction, engagement, and conversion rates, leading to overall business growth and success in the digital era.
