Core Web Vitals as a Ranking Factor

Core Web Vitals are a key set of website performance metrics and factors that Google uses to evaluate the user experience on a website. These metrics are designed to measure how fast a webpage loads, how responsive it is, and how stable its content is during loading. Google introduced Core Web Vitals as part of its effort to prioritize user experience in its ranking algorithm. Any leading web development company in Dubai today gives prominence to important metrics advocated by Google to stay ahead of the curve and boost ranking. The three main metrics that make up Core Web Vitals are:

1. Largest Contentful Paint (LCP)

Largest Contentful Paint measures the user experience in terms of a website’s loading performance. It specifically focuses on the time it takes for the largest content element (such as an image or a block of text) to become visible to the user. Ideally, LCP should occur within 2.5 seconds of a page starting to load. Slow LCP times can result in a poor user experience, leading to higher bounce rates and lower rankings in search results.

2. First Input Delay (FID)

First Input Delay measures a website’s interactivity and responsiveness. It measures the time taken for a web page to respond when the user first interacts (clicking a link or tapping a button). According to Google, an FID of less than 100 milliseconds offers an optimal user experience.

3. Cumulative Layout Shift (CLS)

Cumulative Layout Shift measures visual stability by evaluating how often unexpected layout and content shifts occur during the page loading process. A good CLS score (less than 0.1) means that the content remains stable and predictable throughout the loading process.

Evidence to Prove Core Web Vitals is an Essential Ranking Factor

Google has gradually emphasised the importance of user experience and site performance for several years, and Core Web Vitals are a natural extension of this focus. Here are some compelling pieces of evidence that highlight why Core Web Vitals are essential for SEO:

  • Google’s Announcement
    Google officially announced that Core Web Vitals would become a ranking factor in May 2020. This announcement was a clear signal to webmasters and SEO agencies that optimizing for these metrics was no longer optional. Google’s commitment to user experience and its willingness to incorporate these metrics into its ranking algorithm underscores their significance. Furthermore, in 2021, the Google team reinstated the ranking power of Core Web Vitals in an exclusive “Ask me anything” session.
  • User Experience Matters
    Google’s goal has always been to provide the best possible search experience for users. Websites that load quickly, respond promptly to user interactions, and maintain visual stability are more likely to deliver a positive experience. By incorporating Core Web Vitals into its ranking algorithm, Google is aligning its goals with what users expect from websites.


  • Real-World Impact
    Studies have consistently shown that websites that perform well in these metrics tend to have lower bounce rates, longer session durations, and higher conversion rates. On the flip side, websites with poor Core Web Vitals scores often struggle to retain visitors and convert them into customers or users.
  • Competitive Advantage
    Optimizing for these metrics is shown to provide an edge in the SEO landscape. Websites that optimize their LCP, FID, and CLS scores can beat competitors in search rankings. They can enable a solid online presence and increased organic traffic.
